3.4.5 Peleinae, Alcelaphinae, Hippotraginae

Subfamilies 3. Peleinae, 4. Alcelaphinae, 5. Hippotraginae

The subfamily 3. Peleinae (one species) (I should note, I will include a list of articles that have been (or may be in the future) for each species. I hope (in the near future) to also have a list of places to see each one will appear on the right (these will be added when they can). Obviously, many of these will not yet have any destinations, given the smaller list of places that this site lists, we hope this will grow fast.

Grey Rhebok

Grey Rhebok

The grey rhebok or grey rhebuck, locally known as the vaalribbok in Afrikaans, is native to South Africa, Lesotho, and Eswatini (Swaziland). The specific name capreolus is Latin for ‘little goat’. Generally confined to the higher areas of Southern Africa, they typically inhabit grassy, montane habitats – for example, sourveld – usually 1,000 metres (3,300 ft) above sea level, and carry a woolly grey coat to insulate them from the cold. They are not strictly limited to this habitat as they can be found in the coastal belt of the Cape, almost at sea level.

The grey rhebok is listed as “Near Threatened”, with a population of between 10,000-18,000

4. Subfamily Alcelaphinae - Sassabies, Hartebeest, Wildebeest (6 species)

Hirola

The HIrola ( also known as the Hunters hartebeest or hunters antelope) is a critically endangered species. It was named by H.C.V Hunter (a big game hunter and zoologist) in 1888. It is the only member of the genus Beatragus, and it currently has 300-500 individuals living in the wild (there are none in captivity). It is a widely known fact, that should the Hirola be lost from the wild, it will be the last species in its genus, and therefore the first mammal genus to go extinct in Africa in the modern era. Locals have got behind this species, with 17 conservancies protecting much of the area. There are even efforts to make some of this area devoid of predators, so as to help this species bounce back faster.
Hirola

Tsessebbe, other names regularly used include Topi Sasseby and Tiang

Tsessebbee
The Tsessebbe is part of a group of so called species, which are actually subspecies (there are 5 or 6 subspecies recognized It is closest related to the Bangweulu Tsessebe, Less so, but still very close to the Topi, Korrigum, Coastal Topi and teh Tiang subspecies. Even the Bontebok is very closely related.
  •  Tsessebbes have around 300,000 living wild
  • Korrigum (Senegalese Hartebeest) in 2004, it was numbered 2650, split between 2 national parks. They situation has not improved
  • Topi are doing well with over 100,00
  • Currently, the Tiang still number very high.

Bontebok

Found only in Southern Africa, its range includes South Africa, Lesotho and Namibia

There are 2 subspecies:

  • Bontebok, found around the western cape -2500-3000 (vulnerable IUCN)
  • Blesbok, found in the high-veld. Closely related to the Tsessebe has a population of around 120,000 (Least concern IUCN)
The majority of this is in protected reserves, meaning that the current threat is low and this species should keep growing
Bontebok

Hartebeest

Hartebeest

The Hartebeest – as many as 70 subspecies, local variants and similar have been suggested, however there is only one currently recognized species.

Overall, the species is listed as least concern with a population of around 360,000. The red hartebeest has a population of 130,000, but at the other end the Swaynes hartebeest in Ethiopia is only thought to number 800 in the wild. The Bulbul hartebeast (light blue) is extinct. The Lelwel Hartebeest(green) is considered endangered and has around 70,000 members. The western or Major hartebeest has around 36,000. What is clear, is that if you are travelling to an area where the local hartebeest is struggling, it would be we worth paying to see them, so as to give a value to them

Blue Wildebeest

  • Other names include common wildebeest, white-bearded gnu or brindled gnu.

There has been five subspecies recognized:

 

  • C.t.taurinus (Burchell, 1823), the blue wildebeest, common wildebeest, or brindled gnu Inhabits the dark brown range

  • C. t. johnstoni (Sclater, 1896), the Nyassaland wildebeest, inhabit orange (Tanzania, Mozambique Malawi)
  • C. t. albojubatus (Thomas, 1912), the eastern white-bearded wildebeest, found in the Gold (beside the Yelow)
  • C. t. mearnsi (Heller, 1913), the western white-bearded wildebeest, its range is shown in yellow
  • C. t. cooksoni (Blaine, 1914), Cookson’s wildebeest, is restricted to the Luangwa Valley in Zambia. This is the mighter brown

In addition, the distinctive appearance of a western form, ranging from the Kalahari to central Zambia, suggests that subspecies mattosi (Blaine, 1825) may also prove distinct from subspecies taurinus. The western form can be recognised even at a distance by its upright mane, long beard, and minimal brindling.

There are around 1.5 million of this species living in the wild – so they are not endangered. Having said this, given that 1.3 million (almost 90% of them live in the Serengeti ecosystem), were something to happen, we could be in a very different position..

Blue wildebeest

Black Wildebeest

Black wildebeest

The Black wildebeest is the black wildebeest or white-tailed gnu is one of the two closely related wildebeest species.  It was first described in 1780 by Eberhard August Wilhelm von Zimmermann. It came surprisingly close to extinction, having been hunted as a pest and for its meat and hide.

The current population is now thought to be around 18,000, though 7000 of this is in Namibia (outside their natural range) where they are farmed. Their conservation status is least concern

5. Subfamily Hippotraginae

Addax

The addax , also known as the white antelope and the screwhorn antelope, is an antelope found in the  Sahara Desert. The only member of the genus Addax, it was first described scientifically by Henri de Blainville in 1816. As suggested by its alternative name, the pale antelope has long, twisted horns – typically 55 to 80 cm  in females and 70 to 85 cm in males. Males stand from 105 to 115 cm at the shoulder, with females at 95 to 110 cm. The females are smaller than the males (sexually diamorphic). The colour of the coat depends on the season – in the winter, it is greyish-brown with white hindquarters and legs, and long, brown hair on the head, neck, and shoulders; in the summer, the coat turns almost completely white or sandy blonde.

The addax mainly eats grasses and leaves of any available shrubs, leguminous herbs and bushes and can survive with no more water than that in the plants they eat for long periods of time. Addax form herds of 5to 20 members, consisting of both males and females, but they are led by the eldest female. Due to its slow movements, the addax is an easy target for its predators: humans, lions, leopards, cheetahs and African wild dogs. Breeding season is at its peak during winter and early spring. The natural habitat of the addax are arid regions, semideserts and sandy and stony deserts.

The addax is a critically endangered species of antelope, as classified by the IUCN (though the USFWS lists them as endangered, as the population is thought to have gone from under 100 to around 500 in the last few years) . Although extremely rare in its native habitat due to unregulated hunting, it is quite common in captivity. The addax was once abundant in North Africa; however it is currently only native to Chad, Mauritania, and Niger. It is extirpated from Algeria, Egypt, Libya, Sudan, and Western Sahara, but has been reintroduced into Morocco and Tunisia. On the map, they green areas are where they still live, while the red represent places that they have been reintroduced

Addax

Sable Antelope

Known for its impressive back curving horns, the sable antelope is a large antelope which inhabits wooded savanna in East and Southern Africa, from the south of Kenya to South Africa, with a separated population in Angola.

There are 4 subspecies

  • The southern sable antelope (other names include the common sable antelope, black sable antelope, Matsetsi sable antelope or South Zambian sable antelope) was the first to be described in 1838 and so is considered the nominate subspecies. Often referred to as the black sable antelope because it tends to have the darkest coat, this subspecies occurs south of the Zambezi River, particularly in northern Botswana and in large numbers in the Matsetsi Valley of Zimbabwe, but it is also found in South Africa. Currently, only about 15% pure Matsetsi sable antelopes are thought to exist in South Africa. The Matsetsi sable antelope population in Zimbabwe is only 450 (down from 24,000 in 1994). The sable antelope population in South Africa is about 7,000 (commercial and in reserves). Therefore, the Matsetsi sable antelope population apparently is less than 1,500 and declining. However, most of the sable antelope in the reserves are pure Matsetsi sable antelope. Anglo-American recently started a program of breeding pure Matsetsi sable antelope commercially and keeping them pure.
  • The giant sable antelope (also known as the royal sable antelope) is so named because both sexes are larger and their horns are recognizably longer. It is found only in a few remaining localities in central Angola. It is classified as Critically Endangered on the IUCN Red List and is listed on Appendix I of CITES. There are thought to be less than 1000 left in the wild. Given a war raged for 27 years (ending in 2002), there is little tourism to the country. If this changes it is likely to give impetus for protecting what wildlife that remains.
  • The Zambian sable antelope (also known as the West Zambian sable antelope or West Tanzanian sable antelope) has the largest geographic range of the four subspecies, which extends north of the Zambezi River through Zambia, the eastern Democratic Republic of the Congo and Malawi into southwestern Tanzania. It is classified as Vulnerable (I cannot find a population estimate.
  • The eastern sable antelope (also known as the Shimba sable antelope) is the smallest of the four subspecies. It occurs in the coastal hinterlands of southern Kenya, particularly in the Shimba Hills National Reserve, and ranges through the region east of Tanzania’s eastern escarpment and into northern Mozambique.

In English “great sable antelope”, “sable” or the Swahili name mbarapi are sometimes used. An archaic term used in accounts of hunting expeditions in South Africa is “potaquaine”; the origin and exact application are unclear. Local names include swartwitpens (Afrikaans), kgama or phalafala (Sotho), mBarapi or palahala (Swahili), kukurugu, kwalat or kwalata (Tswana), ngwarati (Shona), iliza (Xhosa), impalampala (Zulu) and umtshwayeli (Ndebele).

Roan Antelope

Roan Antelope

The roan antelope is a large savanna-dwelling antelope found in western, central, and southern Africa. Named for its roan colour (a reddish brown), it has lighter underbellies, white eyebrows and cheeks and black faces, lighter in females. It has short, erect manes, very light beards and prominent red nostrils. It is one of the largest antelope, measuring 190–240 cm  from head to the base of the tail, and a 37–48 cm  long tail. Males weigh 242–300 kg and females 223–280 kg . Its shoulder height is around 130–140 cm.

It was first described by French naturalist Étienne Geoffroy Saint-Hilaire in 1803. It is listed as least concern by IUCN, while CITES places them on appendix 3 (I have been unable to find conservation of the subspecies, but these will be added if/ when I do.

Six subspecies are recognised:

  • H. e. bakeri (Heuglin, 1863): Occurs in Sudan (East Africa). Vulnerable 
  • H. e. cottoni Dollman and Burlace, 1928: Occurs in Angola, Botswana, the southern Democratic Republic of the Congo, central and northern Malawi, and Zambia (Southern Africa).
  • H. e. equinus É. Geoffroy Saint-Hilaire, 1803: Occurs in Mozambique, South Africa and Zimbabwe (Southern Africa).
  • H. e. koba (Gray, 1872): Range extends from Senegal to Benin (West Africa).
  • H. e. langheldi Matschie, 1898: Occurs in Burundi, the northern Democratic Republic of the Congo, Ethiopia, Kenya, Rwanda, South Sudan, Tanzania and Uganda (East Africa).
  • H. e. scharicus (Schwarz, 1913): Occurs in Cameroon, the Central African Republic, Chad and eastern Nigeria (Central Africa).
Roan antelopes can be found in woodland, grassland, and savannah; mainly in the tropical and subtropical grasslands, savannas, and shrublands biome, which range in tree density from forest with a grassy understory (such as the central Zambezian Miombo woodlands) to grasslands dotted with few trees, where they eat mid-length grasses.
 
They live in small groups and form harem groups of 5 to 15 animals with one dominant male. Males commonly fight among themselves for dominance of their herd, brandishing their horns while both animals are on their knees.

Gemsbok

The gemsbok or South African oryx, is a large antelope in the genus Oryx. It is endemic to the dry and barren regions of Botswana, Namibia, South Africa and (parts of) Zimbabwe, mainly inhabiting the Kalahari and Namib Deserts, areas in which it is supremely adapted for survival. Previously, some sources classified the related East African oryx, or beisa oryx, as a subspecies.

The name gemsbok is from Afrikaans, which itself is from the Dutch word of the same spelling, meaning “male chamois”, composed of gems (“chamois”) + bok (“buck, male goat”).

It is on the Namibian coat of arms, as there are roughly 373,000 in the country. They are listed as least concern. Being a desert species, they are only found in South African reserves in the west, and are not found in the Kruger. The closely related East African Oryx lives (unsurprisingly) in east Africa.

Belsa Oryx - Also known as the East African Oryx

Belsa Oryx

The East African oryx  inhabits eastern Africa. The East African oryx has two subspecies;

  • the common beisa oryx (O. b. beisa)
  • the fringe-eared oryx (O. b. callotis).

In the past, both were considered subspecies of the gemsbok. The East African oryx is an endangered species, with 11,000-13,000 mature individuals in the wild.

Scimitar Oryx

The scimitar oryx, also called the scimitar-horned oryx (Oryx dammah), of North Africa used to be listed as extinct in the wild, but it is now declared as endangered. Unconfirmed surviving populations have been reported in central Niger and Chad, and a semi-wild population currently inhabiting a fenced nature reserve in Tunisia is being expanded for reintroduction to the wild in that country. Several thousand are held in captivity around the world.

Schimiter Oryx

6. Subfamily Aepycerotinae (1 species)

Impala

Impala

There are currently around 2 million Impala roaming across Africa.  About one quarter of these live in protected areas in Botswana, Kenya, South Africa, Tanzania, Zambia, and Zimbabwe. Around 1000 of the Black faced Impala live in the green area in the west of Africa.

In some reserves such as the Kruger, they are the most common antelope.

7. Subfamily Antilopinae

Dama Gazelle

The Dama Gazelle is a small antelope, species with a handful of small populations acros central and western north Africa. It lives in the Sahara and the Sahel desert. 

In Niger, the Dama Gazelle has become a national symbol.

There are 3 subspecies, however the Mhorr gazell is extinct in the wild (though zoos have a number) , the dama gazelle is only kept in captivity one zoo and is very rare in the wild. 

The species is critically endangered with only 100-200 left in the wild. Given that this small population is spread over a number of areas. The number of wild semi wild and captive is around 2900, so it is just the need to save the species in the wild which is the current problem.

Schimiter Oryx

Dorcas Gazelle

Dorcas Gazelle

There are currently around 35,000-40,000 dorcas gazelle roaming across the whole of north Africa (though given this large range they are not particularly numerous in any location).  It is unclear how many of these live in protected areas. Some whole countries like Sudan still have these animals but no reserves. in Algeria, Chad, Djibouti, Egypt, Eritrea, Ethiopia, Israel, Jordan, Libya, Mali, Mauritania, Morocco, Niger, Somalia, Sudan, Tunisia, Western Sahara. There are 7 subspecies-

  • Eritrean Dorcas Gazelle or Heuglin’s gazelle (Eritrea, Ethiopia and Sudan): 2500-3500 in the wild. Populations fell around 20% between 2008 and 2016 (unknown what happened since)
  • Egyptian Dorcas Gazelle – status unknown
  • Isabelle Dorcas Gazelle – status unknown
  • Moroccan Dorcas gazelle – Isolated in the M’Sabih Talaa reserve in Morocco for 50 years. Its biggest threats appear to be feral dogs and poaching. Due to factors like this, the population has halved in 15 years,recently. Population numbered 209 in 1987. The most recent survey suggested 100 (in 2013). What has happened in the last 11 years has not been ascertained.
  • Saharan (or Saharawi) dorcas gazelle

Gerenuk

  • The gerenuk is an odd species, which in appearance looks like a cross between an impala and a giraffe. They increase this effect, by standing on their hind legs while they eat. A herd, eating in this way is quite a weird sight.

They are currently classed as not threatened, and have a wild population of around 95000.

Two subspecies are recognized:

  • Northern gerenuk or Sclater’s gazelle (Its range extends from north-western Somalia westward to touch the Ethiopian border and Djibouti.
  • Southern gerenuk or Waller’s gazelle (Its range extends through north-eastern Tanzania through Kenya to Galcaio (Somalia). The range lies north of the Shebelle River and near Juba River.)
It is unclear how the two subspecies split the population, but given each is listed as near threatened, it would suggest that the population is split pretty evenly.
Gerenuk

Grant's Gazelle

Grant's Gazelle

There are currently around 140,000-300,000 Grant’s gazelle roaming through parts of East Africa and in places like the Serengeti are a common sight.  It is unclear how many of these live in protected areas. They can be found from southern Sudan and Ethiopia to central Tanzania and from the coast of Kenya and Somalia to Lake Victoria. They are currently classed as unthreatened. There are 3 subspecies-

  • Northern Grant’s Gazelle  (Ethiopia and Kenya)
  • Southern Grant’s Gazelle – East Africa and found from Central Kenya up to the Samburu Game Reserve down to southern Tanzania around Ruaha National Park.
  • Robert’s grants Gazelle – only found in the Serengeti/Mara ecosystem (it is unclear how many of these gazelles live here, but a total of 500,000 Thompsons and Grant gazelles live in the whole ecosystem

Mhorr Gazelle

  • The gerenuk is an odd species, which in appearance looks like a cross between an impala and a giraffe. They increase this effect, by standing on their hind legs while they eat. A herd, eating in this way is quite a weird sight.

They are currently classed as not threatened, and have a wild population of around 95000.

Two subspecies are recognized:

  • Northern gerenuk or Sclater’s gazelle (Its range extends from north-western Somalia westward to touch the Ethiopian border and Djibouti.
  • Southern gerenuk or Waller’s gazelle (Its range extends through north-eastern Tanzania through Kenya to Galcaio (Somalia). The range lies north of the Shebelle River and near Juba River.)
It is unclear how the two subspecies split the population, but given each is listed as near threatened, it would suggest that the population is split pretty evenly.
Gerenuk

Red-fronted Gazelle

Grant's Gazelle

The red-fronted Gazelle is found in a wide but uneven band across the middle of Africa from Senegal to north-eastern Ethiopia. It mainly lives in the Sahel zone, a narrow cross-Africa band south of the Sahara, where it prefers arid grasslands, wooded savannas and shrubby steppes. There are some people who consider the more famous Thompson gazelle of east Africa a subspecies of the red-fronted Gazelle.

  • Eastern Chad red-fronted gazelle
  • North Nigeria red-fronted gazelle
  • Kanuri red-fronted gazelle
  • Nubian red-fronted gazelle
  • Senegal red-fronted gazelle
There are 25,000 red fronted gazelle (If the Thompson gazelle was a subspecies, then it would outnumber all other subspecies with 550,000 wild individuals).

Slender-horned Gazelle

Also known as the Rhim gazelle, African sand gazelle or Loder’s gazelle while its name in Tunisia and Egypt means white gazelle, it is pale and well suited to the desert, however there are only 2500 of them left in the wild. Widely found, they have populations across They are found in Algeria, Egypt, Tunisia and Libya, and possibly Chad, Mali, Niger, and Sudan (this can be seen on the map opposite).

  • G. l. leptoceros F. Cuvier, 1842 (none in captivity) from Egypt and Libya (north-east) as well as possibly Chad and Niger.
  • G. l. loderi Thomas, 1894 found in Algeria and Tunisia and western Libya

The split between the two subspecies is not well defined. It should be noted that the red list states that there is more than 250 but it may be not that far above. One or both of these subspecies may well be incredibly close to extinction. It should be noted, that even a population of just 250 in the two subspecies, should these two subspecies be in one population each, it could well recover relatively fast.

It is hard to see this species surviving long-term unless poaching stops and perhaps even requiring the amalgamation of all the populations of each subspecies (indeed, we may well be beyond the sensible attempt to save each subspecies and but to merely concentrate on saving the species as a whole.

Slender horned gazelle

Soemmerring's Gazelle

Grant's Gazelle

Also known as the Abyssinian mohr, it is a gazelle species native to the Horn of Africa which includes Djibouti, Eritrea, Ethiopia, Somalia and South Sudan (possibly no longer present here). The species was first described by German physician Philipp Jakob Cretzschmar in 1828. Three subspecies are recognized, which include

  • Nubian Soemmerring’s gazelle (Cretzschmar, 1828)
  • Somali Soemmerring’s gazelle (Matschie, 1893)
  • Borani Soemmerring’s gazelle  (Thomas, 1904)
  • The dwarf population on Dahlak Kebir island might also qualify as a subspecies.

They are classed as vulnerable with a wild population of roughly 6000-7500 with the largest single population being on Dahlak Kebir which is part of Eritrea (this country is estimated to have a population of 3000-4000 (between 40-65% of the worlds population. It has been classed as vulnerable to extinction since 1986, however I would argue that its future survival is probably less good than that sounds. Being largely a desert species, it might be hard to see, but there will still be places where it is found, and as always, a visit should help give the live species more local value.

 

Speke's Gazelle

The Speke’s gazelle is the smallest gazelle and is found in the horn of Africa (Somalia and Ethiopia – though hunted to extinction in Ethiopia). They number roughly in the low 10,000s. Unfortunately having been hunted to extinction in Ethiopia, its one remaining home is a war zone, which does not give us reassurance that it will survive into the future. While the population has increased in recent times, the animal has recently been upgraded from vulnerable to endangered. It takes its name from John Hanning Speke, who was an English explorer in central Africa. It is similar to the Dorcas gazelle, and it has been considered a subspecies at times.

At the current time, there is no reserve within the Speke’s gazelles range, making it hard to see them (this is largely as a result of their remaining reserve likely being exclusively found in Somalia, where war has raged for a very long time.

Gerenuk

Springbok

Grant's Gazelle

The common name “springbok”, first recorded in 1775, comes from the Afrikaans words spring (“jump”) and bok (“antelope” or “goat”). It is only found in South Africa and the south west (including Namibia and southern Botswana and parts of Angola)

Three subspecies recognized

  • A. m. angolensis (Blaine, 1922) – Occurs in Benguela and Moçâmedes (southwestern Angola).
  • A. m. hofmeyri (Thomas, 1926) – Occurs in Berseba and Great Namaqualand (southwestern Africa). Its range lies north of the Orange River, stretching from Upington and Sandfontein through Botswana to Namibia.
  • A. m. marsupialis (Zimmermann, 1780) – Its range lies south of the Orange River, extending from the northeastern Cape of Good Hope to the Free State and Kimberley.

There are 2,000,000-2,500,000 remaining in the wild.

Thompson Gazelle

  • Approximately 550,000 Thompson gazelles remain in the wild, with the largest population being found in the Serengeti Mara ecosystem. Named after Joseph Thompson an explorer, some consider it a subspecies of the red-fronted gazelle.

It is the fourth fastest land animal, after cheetah (its main predator) springbok and pronghorn, and can hit speeds of 80-90km per hour.

Two subspecies are identified:

  • E. t. nasalis (Lönnberg, 1908) – Serengeti Thomson’s gazelle ranges from the Serengeti to the Kenya Rift Valley.
  • E. t. thomsonii (Günther, 1884) – eastern Thomson’s gazelle ranges from east of the Rift Valley in Kenya and Tanzania, southward to Arusha District (Tanzania) and then southwestward to Lake Eyasi, Wembere River, and Shinyanga.
While mainly known as a grazer, they are one during the wet season, but during the dry season they will switch to browsing.
Monty python’s flying circus had a running gag around this species, and there was one in the film Zootropolis.
Gerenuk

Dibatag

Bate's pygmy antelope

Also known as the Clarkes gazelle, it is another species restricted to Ethiopia and Somalia. It is not a true gazelle, though it does still have markings on its legs similar to the gazelles. They are classed as vulnerable, with their biggest threat being poaching.

No reserves protects any of this population. The population is definitely under 10000 and probably under 4000. Their range is also restricted to a 100km by 100km area.

The dibatag is endemic to the evergreen bushland of the Ogaden region of southeastern Ethiopia and adjoining parts in northern and central Somalia. In the past their range extended from the southern parts of northern Somalia through southeastern Ethiopia and central Somalia (between the coastline of the Indian Ocean and bounded by the Fafen River in the west and the Shebelle River in the southwest). Rock paintings of two dibatag were discovered on the west bank of the river Nile and north of the Aswan Dam in Egypt, suggesting a southward migration of the species in the Predynastic period in Egypt.

 

Bate's Pygmy Antelope

Also known as the pygmy antelope, and the dwarf antelope, it is classed as least concern, and is considered fairly common (a precise estimate is not available).

While the species is suffering from habitat loss which means that their future is not necessarily good. In general, they are able to adapt to secondary forest, plantations, roadside verges and village gardens. Although not hunted commercially, this antelope is hunted for bushmeat in limited numbers.

Gerenuk

Beira

Grant's Gazelle

Living in the arid regions of the horn of Africa, this species is classed as vulnerable. Unfortunately, as with other species living in this region, there is little protected land, so this situation may get worse in the near future.

As with others on this list means that while grazing is the normal, they will to browse where it is necessary.

Cape Grysbok

Only found along the extreme southern coast of South Africa, the Cap Grysbok is classed as least concern with a population that is unknown, but is estimated at an upper level of over 200,000, and so it is listed as least concern.

Gerenuk

Guenther's Dikdik

Grant's Gazelle

Guenthers dikdik is another species only found within the horn of Africa and some areas around here. It is classed as least concern, and while there has been 4 subspecies suggested based on looks, no-one has yet looked in more detail to see if this is correct.

The species is found in the lowlands of Ethiopia, most of the northern and eastern regions of Kenya, Somalia excluding specific regions of the coast, limited regions of southeastern Sudan, and north-eastern Uganda. They avoid coastal regions. Typical habitat includes low thicket-type vegetation in thornbush, savanna grassland and riverine woodland biomes, and extends to disturbed and overgrazed areas. Habitat overlaps with other small antelope species such as Kirk’s dik-dik (a similar species which I have encountered in Kenya).

There are a number of protected areas within its range, meaning that its future is more secure than other species that share at least part of its range. The population is estimated at roughly 511,000 individuals.

Kirk's Dikdik

The Kirks dik-dik has two areas of habitat, oddly split, suggesting that at one point their range may have been far larger.

They are classed as least concern, suggesting that at the current time, they are doing well. I have seen these in northern Kenya, and they have an adorable habit of traveling around in pairs. So strong is their bond, that if one leaps out into the road, it is well worth breaking hard, as the other one is highly likely to follow shortly after. They can live in relatively high densities, though changes in predator can make large differences fast. A small reserve I stayed on in northern Kenya, had had a wild dog pack move onto the land. In one year, they had reduced the number of dik-diks by roughly half.

The overall population of this species is thought to be around 971,000.

Gerenuk

Klipspringer

Klipspringer

The klipspringer has a large range, being found across a large range of Africa. In places like the Kruger, virtually ever outcrop of rock has a pair of klipspringers. They are able to stand on particularly steep rocks, which allows them to get away from predators. This is important, as when there are not large enough trees available, leopards will often live in similar places.

It is closely related to the kirks dikdik (above) and the Oribi (below). Mainly active at night, it spends its days resting. It is mainly a browser, feeding on young plants fruits and flowers. They are classed as least concern, and as much of their population is in relatively unfavourable land, rarely hunted. In 2008, an assessment suggested that only 25% of the population live within protected areas. This means that although currently not remotely threatened, this would be an easy species for this to change.

Their population is estimated at around 40,000, though given the large area in which these are found, their distribution is likely to be sparse at best. Finding them, in an area where we know they are, however, is not normally hard – certainly in places like the Kruger they are a relatively easy find.

Given the holes in this species range, it is reasonable to suppose that historically there were more of this species, but if there were, it is likely quite some time ago.

Oribi

A small antelope, though found across a wide range of habitats. They are secretive, and as such are generally seen far less often than their population would suggest. They are rarely seen in the Kruger, but overall are not doing badly.

Their wild population is estimated at 750,000 so are listed as least concern, but this is only an estimate, and they are thought to be declining.

Oribi

Royal Antelope

Grant's Gazelle

This is officially classed as the worlds smallest antelope, standing only 25cm tall at the shoulder, and weighing 2.5kg

Usually active at night, it marks its territory with dung, and is very alert. An herbivore, the royal antelope prefers small quantities of fresh foliage and shoots; fruits and fungi may be taken occasionally. Like other neotragines, the royal antelope is monogamous (capable of having young as early as 6 months old). Births have been reported in November and December. A single, delicate young is born after an unknown gestational period.

In 1999, its population was estimated at 62,000, but this could be an underestimate.

Salt's Dikdik

This species is found in the area marked on the map.

5 subspecies are recognized

  • M. s. saltiana is found from northern Ethiopia to Eritrea and far eastern Sudan, and is relatively large with a reddish-grey back.
  • M. s. hararensis is found in the Hararghe region in eastern Ethiopia, and has a gingery back and dark red flanks.
  • M. s. lawrenci is found in eastern and southeastern Somalia, and has a silvery back and russet flanks.
  • M. s. phillipsi is found in Somaliland, and its back is grey and flanks are orange.
  • M. s. swaynei is found in the Jubba Valley region of southern Ethiopia, southern Somalia, and far northern Kenya; its back is brown-grey.
Though there is some disagreement about whether these are all subspecies, or whether some are actually full species in their own right.
While there is no easy to find estimate on the size of the population, they are listed as least concern

Sharpe's Grysbok

Grant's Gazelle

The Sharpe’s Grysbok, is another small antelope that is found in the east of southern Africa (its most southerly point is the northern Kruger. As a small species, however, it is another antelope that can regularly pass without notice.

It has an estimated 95,000 individuals in the wild and is listed as least concern. Around 1/3 of the population lives within protected ares.

Steenbok

The steenbok (also known as steinbuck or steinbok) is a small species of antelope found in the southern and eastern Africa. Its closest relatives are the dik-diks and gazelles.

There are 650,000 estimated to still live in the wild, and they are classified as least concern.

On the map, you can see where this species is found, however this is also a list of countries where you can find this species. In East Africa, it occurs in central and southern Kenya and northern Tanzania. It was formerly widespread in Uganda, but is now almost certainly extinct there. In Southern Africa, it occurs in Angola, Namibia, South Africa, Eswatini, Botswana, Mozambique, Zambia, Zimbabwe and probably Lesotho. There are 2 subspecies recognized (though as many as 24 have been suggested based on colouring and similar)

Steenbok

Silver Dikdik

Silver dik-dik

Found in dense thickets along the southeastern coast of Somalia and in Acacia-Commiphora bushland in the Shebelle Valley in southeastern Ethiopia, it is listed as data deficient (not surprising given where it originates. It is unfortunately a fact, however, that the majority of species which are found in this area, are in a desperate state. It is true that for many species they do better, when no-one is paying any attention. For instance, the mountain gorilla population grew enormously during the war, as there was to much danger to poach them, although there was also no tourism revenue coming in.

While its weight and size is similar to a domestic cat, While the last estimate was in 1999, with the population put at 30,000, the range has been expanded since (though unfortunately the 30,000 is still probably am over estimate 25 years ago. The likelyhood of this species population growing in this time, is low.

Suni

The Suni is a small species of antelope found from Kenya down to northern South Africa (it is also found on Zanzibar which is off the coast of Tanzania).

The Suni is listed as least concern, and the last time a population estimate was made (1999), they came up with a number of 365,000, a sizeable number (though given the range of this animal, it is not a huge number).

There are 4 subspecies (though some claim these as 4 separate species)

  • Coastal suni — N. m. moschatus (Von Dueben, 1846) — found on the Zanzibar Archipelago (Changuu and Chapwani islands; Jozani, Kendwa, Kizimkazi and Nungwi, Unguja) and coastal Kenya (Arabuko Sokoke Park, Mombasa, Watamu).
  • Livingstone’s suni — N. m. livingstonianus (Kirk, 1865) — South Africa (KwaZulu-Natal), Malawi, inland Mozambique, Zambia and Zimbabwe.
  • Mountain suni — N. m. kirchenpaueri (Pagenstecher, 1885) — Kenya (Aberdare Range, Karura Forest, Mount Kenya, Nairobi National Park) and Tanzania (Arusha National Park).
  • Southern suni — N. m. zuluensis (Thomas, 1898) — South Africa (KwaZulu-Natal, Hluhluwe-Imfozoli, iSimangaliso Wetland Park), Eswatini (Mkhaya Game Reserve), and coastal southern Mozambique (Ponta do Ouro and surrounding areas).

This species population has definitely been reduced by poaching, though they are still abundant. In South Africa, many are killed by dogs.

Abbott's Duiker

Grant's Gazelle

Known as Minde in Swahili is a large forest duiker found in a few small areas of Tanzania (Abbott’s duiker is endemic to Tanzania, in the Eastern Arc Mountains, Mount Kilimanjaro, and Southern Highlands in scattered populations.). There has been some debate about whether this is a separate species or whether it is a subspecies of the yellow-backed duiker. It should be noted that it is only rarely seen, and was only first photographed in 2003. 

They are estimated to have 1500 individuals in the wild, but are threatened by habitat destruction and poaching.

Aders's Duiker

Also known as Nunga, and is found in Kenya and on the island of Zanzibar. It may be a subspecies of the red, Harvey’s, or Peters’s duiker or a hybrid of a combination of these – but is named after W Mansfield Aders – a zoologist with the Zanzibar government service. It is small, only standing 30cm at the shoulder, and weigh between 75.-12kg (the heaviest is in Zanzibar).

The Zanzibar population dropped from 5000-640 between 1983 and 1999, and is estimated to be as low as 300 now (or as high as 600 – the estimates have wide ranges).

Aders's duiker

Bay Duiker

Grant's Gazelle

The bay duiker has a distribution across central and western Africa, and is restricted to areas of rainforest. Also known as the black striped duiker or the black backed duiker. For this duiker family, they are relatively tall, standing at 45-50cm at the shoulder, and weigh 18-23kg.

It is nocturnal and either solitary or living in pairs. Its natural main predator is the leopard, it has been historically over harvested for the bushmeat trade, and loss of habitat for both agriculture and housing has affected it. Never-the-less, its population is still listed as near threatened. Given its ability to sustain despite large quantities of hunting from both humans and leopards, its greatest threat is the loss of the Congo rainforest (unfortunately the greatest threat for many species).

Black Duiker

The black duiker is another species found in the rainforests of west Africa. It is estimated that there are 100,000 of this species in the wild, though how much faith can be placed in this number, is I think an important question. Standing roughly 50cm tall, and weighing 15-20kg.

Black duikers live mainly in lowland rainforest, where they eat fruit, flowers, and leaves which have fallen from the canopy. They are probably diurnal (active during the day), though this has only been worked out from captive specimens (an unreliable system, as many animals have different habits in the wild to in captivity. Black duiker are reported to be solitary, territorial animals. While most young are born between November and January, mating can occur any time of year, and pregnancy lasts roughly 4 months.

Lifespan is not clear in the wild, but in captivity they can live 14 years.

Black duiker

Black-fronted Duiker

Grant's Gazelle

The black-fronted duiker is found in central and west-central Africa, with an isolated population in the Niger Delta in eastern Nigeria and then from southern Cameroon east to western Kenya and south to northern Angola, and occurs in montane, lowland, and swamp forests, from near sea level up to an altitude of 3,500m. It is frequently recorded in wetter areas such as marshes or on the margins of rivers or streams. The black-fronted duiker is territorial and monogamous, each pair owning a territory that it defends against neighbours and is marked using the secretions of the facial glands. The pair have habitual paths within their territory that connect sleeping sites with feeding areas and allow them to be active during both day and night. They are mainly browsers but will also feed on fruit. The currently recognised subspecies are:

  • Cephalophus nigrifrons fosteri St. Leger, 1934
  • Cephalophus nigrifrons hooki St. Leger, 1934
  • Cephalophus nigrifrons hypoxanthus Grubb and Groves, 2002
  • Cephalophus nigrifrons kivuensis Lönnberg, 1919
  • Cephalophus nigrifrons nigrifrons Gray, 1871 .
  • Cephalophus nigrifrons rubidus Thomas, 1901: Known as the Ruwenzori duiker
They are currently listed as least concern, however an estimate on population size is not readily made public.

Blue Duiker

The blue duiker is found in a wide range of habitats. While much of its range falls in countries like the Democratic republic of the Congo (and thereby makes the blue duiker a rainforest species) they also live in large parts of eastern Tanzania, and places like South Africa where there is no rainforest. The habitat consists of a variety of forests, including old-growth, secondary, and gallery forests.

It is currently listed as least concern, but is quite a common source of bushmeat, and as such it is under threat from local extinction. As you can see from the map, its range is quite patchy – while this is partly a result of where woodland is found, it is also likely a result of local extinction.

It is listed as least concern, and is thought to have around 7 million left in the wild.

Gerenuk

Grey duiker (common)

Grey (common) duiker

Also known as the common or bush duiker. It is found throughout almost all of Africa, south of the Sahara.

According to the IUCN Red List, the total Common duiker population size is around 1,660,000 individuals, however, other research has suggested that the total population size of this species is approximately 10 million individuals. This is obviously a far too wide range to have.

I would argue that the population is likely nearer the higher end. If it is not, this species should no longer be listed as common, given species like the blue duiker would be far more common.

Given its wide range, there are many reserves to see this species. I have seen this species in Kruger national park.

Harvey's Red duiker (Harvey's duiker)

The Harvey’s red duiker is found in Tanzania and scattered through Kenya, southern Somalia and possibly central Ethiopia. They stand roughly 40cm tall and weigh around 15kg. They are mostly chestnut coloured, but has black legs. 

Harvey’s duikers live in mountain and lowland forest, where they eat leaves, twigs, fruit, insects, birds eggs, and carrion. Although this duiker is not endangered, it is dependent on protected forestland. As of 2008, this species is of least concern. Total population is roughly 20,000. It is classed as least concern, which suggests that 20,000 is close to the original population size, from where it is found.

Harvey's red duiker

Jentink's Duiker

Jentinks duiker

Jentink’s duiker also known as gidi-gidi in Krio and kaikulowulei in Mende, is a forest-dwelling duiker found in the southern parts of Liberia, southwestern Côte d’Ivoire, and scattered enclaves in Sierra Leone. It is named in honor of Fredericus Anna Jentink.

Recent population numbers are not available. In 1999 it was estimated that around 3,500 Jentink’s duikers remained in the wild, but the following year others suggested less than 2,000 were likely to remain, unfortunately another estimate has not been made in the 25 years since. It is likely that the population did not drop 1500 in a year, but was over counted the first time. Either way this is a small population, but if the drop was that fast, it would be worse than it is currently thought. They are threatened primarily by habitat destruction and commercial bushmeat hunters. They are classed as endangered, but clearly need more information, and I would argue that are more naturally falling into the class of data deficient.

Maxwell's Duiker

A small antelope found in west Africa, first described in 1827 by Charles Hamilton-Smith, it shares a genus with the blue duiker and the Walters duiker

Three subspecies are identified:

  • P. m. danei or P. m. lowei Hinton, 1920 Occurs in Sierra Leone.
  • P. m. maxwelli C. H. Smith, 1827 Occurs in Senegal, Gambia and Sierra Leone.
  • P. m. liberiensis Hinton, 1920 Occurs in Liberia, Ghana and further East
The list of countries in which it is found include  Benin, Burkina Faso, Côte d’Ivoire, Ghana, Guinea, Guinea-Bissau, Liberia, Nigeria, Senegal, Sierra Leone and Togo. 
The Maxwell duiker’s diet mostly consists of fruits, seeds, secondary vegetation and shrubs.
As with many of these, this species is least concern, but it is decreasing.
Maxwells Duiker

Natal Red-duiker

Natal Red duiker

Also known as Red forest duiker (as well as other mixes of these words), is very similar to the common duiker. It is very similar to the common duiker with though with a redder coat.

The last estimate of the population was in 1999, when it was estimated at 42,000.

They are also listed as least concern

Ogilby's Duiker

The two former subspecies, the white-legged duiker Cephalophus crusalbum and the Brooke’s duiker Cephalophus brookei, are considered as distinct species since 2011.

Measuring 56cm at the shoulder and weighing up to 20kg, they mainly live mainly in high-altitude rainforests, where they feed mainly on fallen fruit.

They are estimated at 12,000 and are listed as least concern

Ogilbys duiker

Peter's Duiker

Peters duiker

The Peters duiker is a species found in a region of west African rainforest (see map) living in Gabon, Equatorial Guinea, southern Cameroon, and northern Republic of the Congo. It weighs 18kg and measures 50cm at the shoulder.

There are an estimated 380,000 in the wild and is declining.

Red-flanked Duiker

Measuring 34-37cm tall and 12-14kg, this small species of antelope. They are classed as least concern and have a large range with around 170,000 living in the wild. It has often done well out of deforestation, as it has often expanded its range during these times.

Red-flanked duiker

White-bellied duiker

White-bellied duiker

This species range is shown on the map , and is found in Cameroon, the Central African Republic, the Republic of the Congo, the Democratic Republic of the Congo, Equatorial Guinea, and Gabon, while it is likely to have been extirpated in Uganda.

They are classed as not threatened, and have more than 250,000 in the wild.

Yellow-backed Duiker

The yellow-backed duiker has a wide range  of places it is found (ranging from Senegal and Gambia on the western coast, through to the Democratic Republic of the Congo to western Uganda; their distribution continues southward into Rwanda, Burundi, and most of Zambia).

They are classed as near threatened, with 160,000

Four subspecies are recognized:

  • C. s. curticeps Grubb and Groves, 2002
  • C. s. longiceps Gray, 1865
  • C. s. ruficrista Bocage, 1869
  • C. s. silvicultor (Afzelius, 1815)
 
Yellow-backed duiker

Zebra Duiker

Zebra Duiker

The zebra duiker is a small antelope found primarily in Liberia, as well as the Ivory Coast, Sierra Leone, and occasionally Guinea. They are sometimes referred to as the banded duiker or striped-back duiker. It is believed to be one of the earliest duiker species to have evolved.

Its wild population is estimated at 28,000 and is classed as vulnerable

They are predated on by a range of species including leopards, African golden cats, rock pythons, and the crowned eagle. They are considered Vulnerable by the IUCN due to deforestation, loss of habitat, and overhunting within its range (bush meat).

Walter's Duiker

Measuring 40cm at the shoulder and weighing 4-6kg it was initially described from a bush-meat specimens in 2010 from Togo. It was not seen in the wild until 2021 when it was caught on camera trap. The are  believed to come from the Dahomey Gap, an area of savannah which is a portion of the Guinean forest-savanna mosaic with a relatively dry climate, that extends all the way to the coast in Benin, Togo and Ghana, separating the rainforest zones on either side.

Understandably however, they are classed as data deficient. There is a big concern at the current time, with so little information, that they may get pushed to extinction without fully understanding where they are or what they need in order to survive in the wild.

Having only been photographed once in the wild, there are no animals in zoos, and so should they be lost from the wild, they will be gone for good.

Walkter's duiker

Common Dolphin

Common Dolphin

  • The most abundant cetacean in the world, with around 6 million (it should be noted that there are 1350 humans in the world, for every individual common dolphin).

Despite this fact and its name, the common dolphin is not thought of as the model dolphin (that honour goes to the bottlenose dolphin due to its popular appearances in aquaria and the media). It did, however, feature heavily in Ancient Greek and Roman art and culture, most notably in a mural painted by the Greek Minoan civilization.

It is currently the only member of the genus Delphinus. The common dolphin belongs to the subfamily Delphininae, making this dolphin closely related to the three different species of bottlenose dolphins, humpback dolphins, striped dolphins, spinner dolphins, clymene dolphin, spotted dolphins, fraser’s dolphin and the tucuxi and guiana dolphin.[5] The common dolphin was originally categorized into two different species (now thought to be ecotypes), the short-beaked common dolphin and the long-beaked common dolphin. However, recent evidence has shown that generally long-beaked dolphins of this species have originated from the short-beaked population, and therefore there is no close links between different long-beaked dolphins in any part of the world.

Currently, the common dolphin is divided into four subspecies:

  • D. d. delphis, the nominate subspecies
  • D. d. bairdii, the Eastern North Pacific long-beaked common dolphin
  • D. d. ponticus, the Black Sea common dolphin
  • D. d. tropicalis, the Indo-Pacific common dolphin

A number of fossils were erroneously placed in the same genus, but this has since been corrected. 

Common dolphins can live in aggregations of hundreds or even thousands of dolphins,though are often seen in groups numbering several hundred individuals (with subgroups consisting of 20-30 individuals). Occasionally, different groups will come together to form mega-pods which can consist of over 10,000 dolphins – quite a site to witness. Genetic studies in the Northeast Atlantic suggest that common dolphin pods generally do not consist of close kin, but rather of members that are not closely related. Unlike many delphinids, common dolphins do not live in a matriarchal society. That being said, closely related individuals are usually found in similar geographical locations fairly consistently, providing evidence that this species displays site fidelity (at least in the North-eastern Atlantic). Male common dolphins display greater site fidelity in relation to their kin than females.

Common dolphin pod structure often consists of nursery pods (which includes females and calves), bachelor pods (consisting of all males) and mixed groups of males and females, including sub-adults and calves. Genetic evidence seems to indicate that common dolphins live in fission-fusion societies, where dolphins form pods that are not necessarily stable and do not necessarily consist of related individuals. It is not known if common dolphins form lifelong bonds with other individuals  like the long-term male alliances seen in bottlenose dolphins.

There is some evidence that common dolphins use signature whistles, similar to that of the bottlenose dolphin. These whistles are believed to serve as an acoustic label the dolphin equivalent of a name.  It takes approximately 1 year for a calf to learn its signature whistle after which it remains stable for the rest of a dolphin’s life.

In South Africa, as many as 29 common dolphin signature whistle types were detected. However, it was difficult to determine if each dolphin had its own signature whistle due to the vast number of dolphins present (over 1,000) and anthropogenic background noise. Additionally, considering the vast number of dolphins present and  taking into account their feeding and diving behaviour, it appears that common dolphin signature whistles are also used for group cohesion. Another hypothesis for the function of signature whistles, is that they serve as a beacon for lost individuals.

Common dolphins sometimes associate with other dolphin species, such as pilot whales (note, not actually whales). In the Gulf of Corinth, common dolphins frequently display mixed species association, especially with striped and Rissos’ dolphins. Over one third of all dolphin sightings in the gulf consisted of mixed species associations that partially consisted of common dolphins. In mixed species associations, the ratio of striped to common dolphins ranged from 6-11:1. When Rissos’ dolphins were present (there would usually be only one or two individuals), it appeared that much of their scars were the result of interactions between striped and spinner dolphins. In much of the interactions, the Rissos’ dolphins would chase and herd the common dolphins toward the boat, while the common dolphins would try and swim under the Rissos’ dolphin. When groups of common and striped dolphins would charge at each other, the Rissos’ dolphin would chase the striped dolphins. Sometimes these interactions appeared to be playful, and at other times aggressive. Synchronized swimming and surfacing was commonly observed. These interactions take place in the deepest part of the Gulf, furthest from shore and usually consist of a total of 60 dolphins from all three species.

There have been 15 cases of common dolphin and striped dolphin hybrids being recorded. Genetic and observational evidence has demonstrated that the hybrids are fertile and are capable of not only reproducing with other hybrids, but are capable of reproducing with each of the parent species. Striped dolphins have been known to mate with other dolphins, as the Clymene dolphin is the result of hybrid speciation between striped and spinner dolphins. However, this is unlikely to happen with common dolphins, as their population in the Gulf of Corinth is too low. Common dolphins and bottlenose dolphins have been known to interbreed in captivity. There is one confirmed case of a hybrid between a bottlenose and common dolphin in Southern Spain, an important feeding ground for both species. The mother was a female bottlenose dolphin (dubbed as Billie) who has spent 10 years within a common dolphin pod. Billie was observed assisting common calves reach the surface at three different intervals and would babysit the calves after the mother went through labour. They have also been observed bow riding on baleen whales, and they also bow ride on boats. They are fast swimmers and breaching behaviour and aerial acrobatics are common with this species. They are also known to display altruistic behaviours to support injured members.

The short-beaked common dolphin is pregnant for 10 to 11 months. The new-born calf has a length of 70 to 100 centimetres (2.3 to 3.3 ft) and weighs about 10 kilograms. For the Black Sea population, weaning occurs at between five and six months, but occurs later (up to about 19 months) in other areas. Typical interbirth interval ranges from one year for the Black Sea population to three years for eastern Pacific Ocean populations. Age of sexual maturity also varies by location, but can range between two and seven years for females and three and 12 years for males. No evidence exists of any major reproductive differences between the two species. In captivity, the long-beaked common dolphin has hybridized with the common bottlenose dolphin . One of the hybrids has been bred back to a bottlenose dolphin, demonstrating such hybrids are fertile.

Indo-pacific bottlenose dolphin

Indo-Pacific Bottlenose dolphin

The Indo-Pacific bottlenose dolphin is a species of Bottlenose dolphin. This dolphin grows to 2.6 m long, and weighs up to 230 kg . It lives in the waters around northern Australia , South China, the Red Sea, and the eastern coast of Africa. Its back is dark grey and its underside is lighter grey or nearly white with grey spots. The Indo-Pacific bottlenose dolphin is usually smaller than the Common bottlenose dolphin, has a proportionately longer Rostrum, and has spots on its belly and lower sides. It also has more teeth than the common bottlenose dolphin — 23 to 29 teeth on each side of each jaw compared to 21 to 24 for the common bottlenose dolphin.

Much of the old scientific data in the field combine data about the Indo-Pacific bottlenose dolphin and the common bottlenose dolphin into a single group, making it effectively useless in determining the structural differences between the two species. The IUCN lists the Indo-Pacific bottlenose dolphin as “near threatened” in their Red List of endangered species.

Until 1998, all bottlenose dolphins were considered members of the single species Tursiops truncatus. In that year, the Indo-Pacific bottlenose dolphin was recognized as a separate species. Both species are thought to have split during the mid-Pleistocene, about 1 million years ago. Some evidence shows the Indo-Pacific bottlenose dolphin may actually be more closely related to certain dolphin species in the Delphinus (genus), especially the “Atlantic spotted dolphin”, than it is to the common bottlenose dolphin. However, more recent studies indicate that this is a consequence of reticulate evolution (such as past hybridization between Stenella and ancestral Tursiops and incomplete lineage sorting, and thus support truncatus and T. aduncus belonging to the same genus. Burrunan dolphin T. (aduncus) australis has been alternately considered its own species, a subspecies of T. truncatus, or a subspecies of T. aduncus. Following the results of a 2020 study, the American Society of Mammologists presently classifies it as a subspecies of T. aduncus. The same study delineated 3 distinct lineages within T. aduncus which could each be their own subspecies: an Indian Ocean lineage, an Australasian lineage, and the Burrunan dolphin. The Society for Marine Mammalogy does not recognize the Burrunan dolphin as a distinct species or subspecies, citing the need for further research. Indo-Pacific bottlenose dolphins are very similar to common bottlenose dolphins in appearance. Common bottlenose dolphins have a reasonably strong body, moderate-length beak, and tall, curved dorsal fins; whereas Indo-Pacific bottlenose dolphins have a more slender body build and their beak is longer and more slender. 

Indo-Pacific bottlenose dolphins feed on a wide variety of fish Cephalopod, Squid, researchers looked at the feeding ecology of Indo-Pacific bottlenose dolphins by analysing the stomach contents of ones that got caught in the gillnet fisheries off Zanzibar, Tanzania.  Indo-Pacific bottlenose dolphins live in groups that can number in the hundreds, but groups of five to 15 dolphins are most common. 

In some parts of their range, they spend time with the common bottlenose dolphin and other dolphin species, such as the humpback dolphin. The peak mating and calving seasons are in the spring and summer, although mating and calving occur throughout the year in some regions. Gestation period is about 12 months. Calves are between 0.84 and 1.5 Meters, and weigh between 9 and 21kg. The calves are weaned between 1.5 and 2.0 years, but can remain with their mothers for up to 5 years, some mothers will give birth again, shortly before the 5 years are up. 

In some parts of its range, this dolphin is subject to predation by sharks. 

Its lifespan is more than 40 years. Indo-Pacific bottlenose dolphins located in Shark Bay, Australia, have been observed using sponges as tools in a practice called “sponging”. A dolphin breaks a marine sponge off the sea floor and wears it over its rostrum, apparently to probe substrates for fish, possibly as a tool. Spontaneous ejaculation in an aquatic mammal was recorded in a wild Indo-Pacific bottlenose dolphin near Mikura Island, Japan, in 2012. Indo-Pacific bottlenose dolphins have been observed to swim near and rub themselves against specific types of corals and sponges. A team of scientists followed up on this behaviour and discovered metabolites with antibacterial, antioxidative, and hormonal activities in the corals and sponges, suggesting that they might be used by the dolphins to treat skin infections. its near-shore distribution, though, makes it vulnerable to environmental degradation, direct exploitation, and problems associated with local fisheries. 

The major predators of this species are typically sharks, and may include humans, killer whales, and sting rays. In the early 1980s, many were deliberately killed in a Taiwanese driftnet fishery in the Arafura Sea, off north western Australia. Large-mesh nets set to protect bathers from sharks in South Africa and Australia have also resulted in a substantial number of deaths. Gillnets are also having an impact, and are a problem throughout most of the species’ range.

These small cetaceans are commonly found in captivity, causing conservation concerns, including the effects of removing the animals from their wild populations, survival of cetaceans during capture and transport and while in captivity, and the risks to wild populations and ecosystems of accidentally introducing alien species and spreading epizootic diseases, especially when animals have been transported over long distances and are held in sea pens.

Bottlenose dolphins are the most common captive cetaceans on a global scale. Prior to 1980, more than 1,500 bottlenose dolphins were collected from the United States, Mexico, and the Bahamas, and more than 550 common and 60 Indo-Pacific bottlenose dolphins were brought into captivity in Japan. By the late 1980s, the United States stopped collecting bottlenose dolphins and the number of captive-born animals in North American aquaria has increased from only 6% in 1976 to about 44% in 1996. South Korea, in the 2010s, environmental groups and animal protection groups led a campaign ko:2013 to release southern bottlenose dolphins illegally captured by fishermen and trapped in Jeju Island.

In a study on three populations of Indo-Pacific bottlenose dolphins in Japan, the characteristics of acoustic signals are believed to be affected by the acoustic environments among habitats, and geographical variation in animal acoustic signals can result from differences in acoustic environments; therefore, the characteristics of the ambient noise in the dolphins’ habitats and the whistles produced were compared. Ambient noise was recorded using a hydrophone located 10 m below the surface and whistles were recorded by using an underwater video system. The results showed dolphins produced whistles at varying frequencies with greater modulations when in habitats with less ambient noise, whereas habitats with greater ambient noise seem to cause dolphins to produce whistles of lower frequencies and fewer frequency modulations. Examination of the results suggest communication signals are adaptive and are selected to avoid the masking of signals and the decrease of higher-frequency signals. They concluded ambient noise has the potential to drive the variation in whistles of Indo-Pacific bottlenose dolphin populations.

Small, motorized vessels have increased as a source of anthropogenic noise due to the rise in popularity of wildlife viewing such as whale watching. Another study showed powerboat approaches within 100 m altered the dolphin surface behaviour from traveling to milling, and changed their direction to travel away from the powerboat. When the powerboat left the area and its noise ceased, the dolphins returned to their preceding behaviour in the original direction.

In Shark Bay, Western Australia, on dolphin behavioural responses showed significant changes in the behaviour of targeted dolphins were found when compared with their behaviour before and after approaches by small watercraft. Dolphins in the low-traffic site showed a stronger and longer-lasting response than dolphins in the high-traffic site. These results are believed to show habituation of the dolphins to the vessels in a region of long-term vessel traffic. However, when compared to other studies in the same area, moderated responses, rather, were suggested to be because those individuals sensitive to vessel disturbance left the region before their study began. Although these studies do show statistical significance for the effects of whale-watching boats on behaviour, what these results mean for long-term population viability is not known. The Shark Bay population has been forecast to be relatively stable with little variation in mortality over time. The Indo-Pacific bottlenose dolphin populations of the Arafura and the Timor Sea are listed on Appendix II of the Convention on the Conservation of Migratory Species of Wild Animals “Bonn Convention”. They are listed on Appendix II as they have an unfavourable conservation status or would benefit significantly from international co-operation organised by tailored agreements. The Indo-Pacific bottlenose dolphin is also covered by Memorandum of Understanding for the Conservation of Cetaceans and Their Habitats in the Pacific Islands Region Adelaide Dolphin Sanctuary “Marine protected area”  in the Australian state of South Australia Gulf St Vincent, which was established in 2005 for the protection of a resident population of Indo-Pacific bottlenose dolphins.

North Pacific right whale

North Pacific right whale

The North Pacific right whale is in a similar position. In the eastern North Pacific there is a population of 30-35, while the western North Pacific is around 300.

It should be noted, that despite this numbers, the North Pacifi right whale is only considered Endangered. not critically endnagered.

While hunting was the initial driver to drop the population. Current threats include ship strikes, as well as entanglement in fishing gear, and of course the small size of the population. Some of the places with the highest density are Bering Sea, Gulf of Alaska, Okhotsk Sea, Kuril Islands, and Kamchatka area, though I should mention that this is a huge area, so does not help a great deal.

Below is a video of a rare sighting of this species. Below that is a list of references to this species on this website (if any). Below this, we will add any opportunities to see this species in the wild.

Indo-Pacific humpback dolphin

Indo- Pacific humpback dolphin

Found in the eastern Indian and western Pacific oceans, this dolphin inhabits coastal waters in this part of the world. It is also known as the Chinese White dolphin

Coloured grey, pink or white (the pink colour comes from blood vessels near the surface rather than from pigmentation) they have a length of 2m-3.5m in length and a weight of 150kg-230kg. They generally spend their time in groups not larger than 10 individuals.

These are not dolphins who go under for long periods of time, with adults rarely diving for more than 4 minutes. Similar threats to other dolphins, include coastal developments, water pollution, overfishing and an increased number of boats in the water. In 2015 it was classified as vulnerable.

A small population of the dolphins (158) live close to Hong Kong and many have succumbed as a result of toxins ingested from the water.

Because they spend much of their time in shallow water close to the shore, they are more at risk to pollution from things like plastic that can wash into the sea. Plastic also makes it harder or impossible for the dolphins to locate fish with echolocation as a result of the extra things in the body of water. 

Below here is a section which will list every time they have been mentioned on the website. Below that, is a video of these animals. Below that you will find any links (as we make them) which will help you see these animals in the wild.

Narrow-ridged (or East Asian) finless porpoise

Narrow ridged (east Asian) finless Porpoise

This species is native to the East China Sea, Yellow Sea, and the seas around Japan. The Yangtze finless was originally thought to be a subspecies of this porpoise, though further study showed its differences to be greater than that (hence it now being recognized as a separate species). The east asian finless porpoise is a subspecies of the narrow ridged finless porpoise (the above picture is one of these).

Growing to 2.27m at most, and 72kg, though most are smaller.

They generally stay in water 50m deep or less, and mostly stay close to shore (though not always – it has been spotted over 100km from land).

The biggest threat to them is habitat degradation and pollution. The population has fallen by 50% in the last 3 generations.

They have been kept in captivity in Japan, Indonesia and China. A total of 94 are thought to have been held. Unfortunately these do not live long, and of all of the pregnancies that have occurred in captivity, only 2 resulted in a love birth and this did not survive for long.

Harbour Porpoise

Harbour Porpoise

This is one of the smallest cetaceans, which spends the majority of its time in estuaries and harbours – though it will sometimes venture up rivers, and have been found 100km from the coast.

They get their name from an anglicized version of the french word Porpois. This in turn comes from a medieval Latin amalgamation of two word – these are porcus (pig) and Piscus (fish). I think that these names are rather unfair, but still.

Its range is the North Atlantic, North Pacific and the Black sea. The populations are not continuous and as such there is a series of sub-populations that are geographically limited.

They are thought to have a global population of around 700,000, the Baltic sea is the only one which is seriously endangered, and that is the Baltic sea population which is thought to be around 500. Others could become endangered if current trends continue such as the Black sea population which is currently estimated to number around 12,000.

They have to spend a great deal of time looking for food, as they need to eat 7-8% of their bodyweight each day.

Generally, they live 8-13 years although individuals have been recorded living to over 20.

Beluga Whale

Beluga Whale

Beluga whales are only found in the arctic and sub-arctic oceans. They are one of just 2 species in their family Monodontidae, and are unique in their genus of Delphinapterus. It is also known as the white whale, the sea canary and the Melon-head (though the melon-headed dolphin is a species of its own, so this name may cause some confusion.

Adaptions it has for the Arctic, include the fact that it is white in colour, allowing it to blend into the white world more effectively, and the fact it has no dorsal fin, which allows it to swim very close to the ice sheet above.

Growing up to 5.5m in length and up to 1600kg they are a pretty large dolphin. Generally, living in groups of around 10, in the summer, they group together in their hundreds or thousands.

The worlds population is thought to be around 200,000, Some populations move from the edge of the ice cap, into rivers in warmer areas, while others stay around the ice caps year round. Groups of people in both USA and Russia have hunted them for many centuries.

Hunting is not controlled, and as such the drop in population could happen quite fast. Russia and Greenland have killed enough to drop their local population significantly, though thankfully not Alaska or Canada.

They do also have their natural predators in both the killer whale and the Polar bear.

They are the most commonly kept cetaceans in the world, with around 300 in captivity. Japan, USA, Ukraine, Canada, China and Russia as well as a few more.

There are 22 populations around the world, these vary from 39,000 down to as little as 500. The total population is around 200,000. While this number is large, the number hunted is definitely not sustainable. There is also no care to distinguish the different populations, which suggests that sub-populations could be pushed to extinction without any care.

Below, you will find a clip from a bbc documentary which features this species. Below this, is a list of any mentions that the beluga whale has had on this site.

Pygmy Sperm Whale

 The Pygmy sperm whale is one of just two species from the Superfamily Kogiidae, the other one being the Sperm whale. They are seen very rarely, with the majority of the knowledge about them, coming from carcasses that wash up on the beach. It was first described in 1834 based on a skull that washed up on the coast of france in 1784 (50 years earlier). While originally placed in the same genus as the sperm whale, it was moved to its own genus Kogia, as it is actually a species which is half way between the dolphins and the sperm whale.

They grow to around 3.5m, which is smaller than many dolphin species.

It has a far smaller brain than the sperm whale (even by comparison size) which my explain why it has such a lot more simple social life.

Pygmy sperm whales are found throughout the tropical and temperate waters of the Atlantic, Pacific, and Indian Oceans, though there are also seen regularly off Russia. Fossils in Japan, Italy South Africa have been found, suggesting that they were more widely spread. The problem is, that seen rarely at sea, and with most of what we know about coming from carcasses, we have little idea if dead and dying animals behave differently to healthy ones.

Seen rarely, I have been unable to find out how long they can hold their breath, though as the sperm whale can hold its breath for 90 minutes, so its likely that the pygmy sperm whale is also an impressive breath holder – this would explain why they are seen so rarely.

Humpback whale

Humpback whale

The humpback whale is a widely recognized species. Weighing around 40 tonnes, and measuring 14-17m. It is known for its habit of breaching (as above) which can be heard from miles away, and its incredibly complex song, which can last between 4 minutes and 33.

Their low sounds can be heard by whales 1000 miles away, and have been picked up by electronic sources far further away than that.

Whaling did horrific damage to this species, with their population falling to just 5000 in the 1960s. Thankfully, having been protected, the population is now around 135,000. Subspecies are more varied, with those in the northern hemisphere less secure. The least secure is the Arabian sea population, which is thought to be isolated for 70,000 years and there are only 80 that remain.

Threats to individual whales include entanglement in fishing gear, ocean noise and collisions with ships.

They are known to have hunting methods more complex than most baleen whales, including bubble netting which forces the fish into tighter shoals to then be taken in one mouthful.

Young are predated by orca in some parts of the world, and many carry scars from these encounters to the end of their lives.
