Do not buy a hydrogen boiler!

The UK watchdog (amongst many other groups) have concluded that hydrogen boiler is a stupid idea. It is true that its only waste product is water and oxygen, but the cost of making the hydrogen is very high.

Should there be large quantities of hydrogen sitting around, then this might make sense – burning hydrogen is generally a very clean fuel. The problem is, that it is almost impossible to store or transport it without loosing much on route, and it is incredibly expensive to split water – the current form for the vast majority of the hydrogen on the planet. Fossil fuel companies are keen, because their old methods can extract and split hydrogen, but it will mean large carbon emissions as well, so is useless – there is a reason that it is called grey hydrogen. Green hydrogen is the only kind that will give us any profit as a world.

So why is the government supporting the switch (alongside gas focused industry). The department for energy security and net zero stated this week that the gas network ” will always be part of our energy system”. I am not sure why anyone would look at it, given an air-source heat pump is likely to be around price parity, and ground source heating even cheaper.

Installation, at the cheap end will be far cheaper than a heat-pump, but this will be more than made up for over the lifetime of the device. Furthermore, with the grants currently available, you are far better off going straight to a heat pump. This is a waste of time and money, and it would not be remotely surprising, if you had to remove it before the end of its life,as it would be costing too much

Albino panda spotted in the wild

Rare albino panda seen again

If anyone has been reading this blog for some time, you may remember me writing about an albino panda that was photographed in wulong nature reserve in China (click here to read it)

This bear has been caught on camera (see above) and appears to be doing well. It has started to display mating behaviour and appears to be extremely healthy. It has all the features generally associated with albinism, with white fur and red eyes.. It is now around 5-6 years old, and has been seen playing with other pandas, suggesting that its unusual colouring is not leading to it being shunned from other pandas.

It was filmed approaching a mother with a 2 year-old cub. As the mother was ready to mate again, and yet did not show aggression to this male bear getting close, it is likely that this female is the mother of the white cub.

Currently thought to be numbered 1800 in the wild, the panda is currently listed as threatened – having been delisted from being endangered in 2016. It is also an integral part of the Giant panda national park which is being created, and links 67 panda reserves, allowing the bears to travel between the former islands of habitat, giving them the ability to breed in a more natural way. This is important, as inbreeding would make panda conservation even harder.

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

The subfamily 3. Peleinae (one species)

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 waterbuck  is a large antelope found widely in sub-Saharan Africa.It was first described by Irish naturalist William Ogilby in 1833.

Its 13 subspecies are grouped under two varieties: the common or ellipsiprymnus waterbuck and the defassa waterbuck. The head-and-body length is typically between 177 and 235cm  and the typical height is between 120 and 136cm. In this antelope, males are taller and heavier than females. Males reach roughly 127 cm at the shoulder, while females reach 119cm. Males typically weigh 198–262 kg and females 161–214 kg. Their coat colour varies from brown to grey. The long, spiral horns, present only on males, curve backward, then forward, and are 55–99 cm long. Waterbucks are rather sedentary in nature. As gregarious animals, they may form herds consisting of six to 30 individuals. These groups are either nursery herds with females and their offspring or bachelor herds. Males start showing territorial behaviour from the age of 5 years, but are most dominant from the six to nine. The waterbuck cannot tolerate dehydration in hot weather, and thus inhabits areas close to sources of water. Predominantly a grazer, the waterbuck is mostly found on grassland. In equatorial regions, breeding takes place throughout the year, but births are at their peak in the rainy season. The gestational period lasts 7–8 months, followed by the birth of a single calf.

Waterbucks inhabit scrub and savanna areas along rivers, lakes, and valleys. Due to their requirement for grasslands and water, waterbucks have a sparse ecotone distribution. The IUCN lists the waterbuck as being of least concern. More specifically, the common waterbuck is listed as of least concern. while the defassa waterbuck is near threatened. The population trend for both is downwards, especially that of the defassa, with large populations being eliminated from certain habitats because of poaching and human disturbance.

The common waterbuck is listed as least concern, while the Defassa is listed as near threatened. Only 60% of this subspecies population is in protected areas, so it could get worse, if they are lost.

Sable Antelope

Sable Antelope

The Nyala is a spiral horned species

 found in Southern Africa. The nyala is mainly active in the early morning and the late afternoon. It generally browses during the day if temperatures are 20–30 °C  and during the night in the rainy season. The nyala feeds upon foliage, fruits and grasses, and requires sufficient fresh water. It is a very shy animal, and prefers water holes to the river bank. Not territorial, they are very cautious creatures. They live in single-sex or mixed family groups of up to 10 individuals, but old males live alone. They inhabit thickets within dense and dry savanna woodlands. The main predators of the nyala are lion, leopard and African wild dog, while baboons and raptorial birds prey on juveniles. Males and females are sexually mature at 18 and 11–12 months of age respectively, though they are socially immature until five years old. They have one calf after 7 months of gestation. Its population is stable, with the greatest threat coming from habitat loss as humans expand. There are thought to be 36500 and the population is stable.

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.

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.

Bushbuck

Bushbuck

The Cape bushbuck , also  known as imbabala is a common, medium-sized and a widespread species of antelope in sub-Saharan Africa. It is found in a wide range of habitats, such as rain forestsmontane forests, forest-savanna mosaic, savanna, bushveld, and woodland. Its stands around 90 cm at the shoulder and weigh from 45 to 80 kg. They are generally solitary, territorial browsers.

Although rarely seen, as it spends most of its time deep in the thick bush, there are around 1 million in Africa

Common Eland

 The common eland (southern eland or eland antelope) is a large-sized savannah and plains antelope from East and Southern Africa. An adult male is around 1.6 m  tall at the shoulder (females are 20 cm  shorter) and can weigh up to 942 kg with a typical range of 500–600 kg. Only the giant eland is (on average bigger). It was described by Peter Simon Pallas in 1766. Population of 136,000, can form herds of 500

Common Eland

Giant Eland

Giant Eland

The giant eland, (also known as Lord Derby’s eland and greater eland) is an open-forest and savanna antelope.

 It was described in 1847 by John Edward Gray. The giant eland is the largest species of antelope, with a body length ranging from 220–290 cm (87–114 in). There are two subspeciesT. d. derbianus and T. d. gigas.

The giant eland is a herbivore, living in small mixed gender herds consisting of 15–25 members. Giant elands have large home ranges. They can run at up to 70 km/h.  They mostly inhabit broad-leafed savannas and woodlands and are listed as vulnerable and have a wild population of 12,000-14,000

Greater Kudu

The greater kudu  is a large woodland antelope, you can see its distribution on the map. Despite occupying such widespread territory, they are sparsely populated in most areas due to declining habitat, deforestation, and poaching. 

The spiral horns are impressive, and grow at one curl every 3 years – they are fully grown at 7 and a half years with 2 and a half turns. Three subspecies have been agreed (one described has been rejected) :

 

  • T. s. strepsiceros – southern parts of the range from southern Kenya to Namibia, Botswana, and South Africa
  • T. s. chora – northeastern Africa from northern Kenya through Ethiopia to eastern Sudan, Somalia, and Eritrea
  • T. s. cottoni – Chad and western Sudan
They are listed as near threatened with 118,000 in the wild
Greater Kudu

Lesser Kudu

Lesser Kudu

The lesser kudu  is a medium-sized bushland antelope found in East Africa.  It was first scientifically described by English zoologist Edward Blyth (1869).It stands around 90 cm at the shoulder and weigh from 45 to 80 kg. They are generally solitary, territorial browsers.

While currently rated not threatened, its population is decreasing. It currently stands at 100,000, but it is loosing territory to humans

Common Bongo (and mountain Bongo)

The bongo  is a large, mostly nocturnal, forest-dwelling antelope, native to sub-Saharan Africa. Bongos are characterised by a striking reddish-brown coat, black and white markings, white-yellow stripes, and long slightly spiralled horns. It is the only member of its family in which both sexes have horns. Bongos have a complex social interaction and are found in African dense forest mosaics. They are the third-largest antelope in the world.

The Common (western or lowland bongo), faces an ongoing population decline, and the IUCN considers it to be Near Threatened.

The mountain bongo (or eastern) of Kenya, has a coat even more vibrant than the common version. The mountain bongo is only found in the wild in a few mountain regions of central Kenya. This bongo is classified by the IUCN  as Critically Endangered (where it breeds readily). (this is not on the map above). Only 100 live wild, split between 4 areas of Kenya

Its population is stable, with the greatest threat coming from habitat loss as humans expand. There are thought to be 36500 and the population is stable.

Mountain Nyala

 The mountain Nyala (also known as the Balbok) is a large antelope found in high altitude woodlands in just a small part of central Ethiopia. The coat is grey to brown, marked with two to five poorly defined white strips extending from the back to the underside, and a row of six to ten white spots. White markings are present on the face, throat and legs as well. Males have a short dark erect crest, about 10 cm (3.9 in) high, running along the middle of the back. Only males possess horns.

The mountain nyala are shy and elusive towards human beings. They form small temporary herds. Males are not territorial. Primarily a browser. They will grazing occasionally. Males and females are sexually mature at 2 years old.. Gestation lasts for eight to nine months, after which a single calf is born. The lifespan of a mountain nyala is around 15 to 20 years.

Found in mountain woodland -between 3000m and 4000m. Human settlement and large livestock population have forced the animal to occupy heath forests at an altitude of above 3,400 m (11,200 ft). Mountain nyala are endemic to the Ethiopian highlands east of the Rift Valley. As much as half of the population live within 200 square km (77 sq mi) area of Gaysay, in the northern part of the Bale Mountains National Park. The mountain nyala has been classified under the Endangered category of the  (IUCN). Their influence on Ethiopian culture is notable, with the mountain nyala being featured on the obverse of Ethiopian ten cents coins.

Situnga Antelope

Common Eland

The sitatunga  (or marshbuck)is a swamp-dwelling medium-sized antelope found throughout central Africa (see the map to the right. The sitatunga is mostly confined to swampy and marshy habitats. Here they occur in tall and dense vegetation as well as seasonal swamps, marshy clearings in forests, riparian thickets and mangrove swamps.

The scientific name of the sitatunga is Tragelaphus spekii. The species was first described by the English explorer John Hanning Speke in 1863.

It is listed as least concern with 170,000-200,000, and are found in 25 countries. However 40% live outside reserves, so the situation could get worse fast.

Note: these animals have been dealt with in less detail than others. Should you be interested in finding out if I have written on these animals or what exactly I said, you can find you by searching for it in the box at the bottom of the page.

Boher Reedbuck

Boher Reedbuck

The bohor reedbuck  is an antelope native to central Africa.

The head-and-body length of this medium-sized antelope is typically between 100–135 cm. Females are smaller. This sturdily built antelope has a yellow to grayish brown coat. Only the males possess horns which measure about 25–35 cm long. There are 5 subspecies:

  • R. r. bohor Rüppell, 1842: Also known as the Abyssinian bohor reedbuck. It occurs in southwestern, western and central Ethiopia, and Blue Nile (Sudan).
  • R. r. cottoni (W. Rothschild, 1902): It occurs in the Sudds (Southern Sudan), northeastern Democratic Republic of the Congo, and probably in northern Uganda.
  • R. r. nigeriensis (Blaine, 1913): This subspecies occurs in Nigeria, northern Cameroon, southern Chad and Central African Republic.
  • R. r. redunca (Pallas, 1767): Its range extends from Senegal east to Togo. It inhabits the northern savannas of Africa. 
  • R. r. wardi (Thomas, 1900): Found in Uganda, eastern Democratic Republic of the Congo and eastern Africa. 
The total population of this species is 100,000, and while it is decreasing, it is not currently low enough to justify a near threatened rating, though this might change in the near future. At the current time, I cannot see any of the subspecies being in a worse position but can change this if I find out more.

Mountain Reedbuck

 The mountain reedbuck has 3 subspecies. The western mountain reedbuck only has 450 individuals still living wild, (shown on the map in red) also known as the Adamwa mountain reedbuck which is restricted to the highlands of Cameroon. The Eastern mountain reedbuck (or Chanlers) has 2900 wild individuals, is found in parts of Kenya and Ethiopia. The Southern moutnain reedbuck, blue, (33,000) is found in the Drakensburg mountains of South Africa.

Mountain Reedbuck

Southern Reedbuck

Southern Reedbuck

The Southern, or common Reedbuck is found in Southern Africa. It is a midsized  antelope, standing 134-167cm tall

 It was described in 1785 by Pieter Boddaert. Southern reedbucks live in pairs or alone, though occasionally they will form herds of up to 20. They prefer to lie in grass or reed beds in the heat of the day and feed during sunrise and sunset, or sometimes even at night. Old reedbucks are permanently territorial, with territories around 35-60 hectares, and generally live with a single female, preventing contact with rival males. Females and young males perform an ‘appeasement dance’ for older males.  Within this territory, it is active all the time in summer, but it is nocturnal in the wet season. It regularly uses paths to reach good sites to rest, graze, and drink water. They are hunted by all the top predators in the area, including Lion, Leopard, Cheetah hyena and wild dog, as well as animals like snakes.

They are easily hunted, and combined with loss of territory to human expansion, the population is down. About 60% occur in protected reserves, but in some countries like Gabon and the DRC are though to almost be locally extinct.

Kob

Red Lechwe antelope are found in a band across Africa, including areas of Eastern, Central and Western Africa.

There are 3 subspecies:

  • The western kob, is found in the west
  • The Ugandan Kob is found in sub-Saharan Africa in South Sudan, Uganda and the Democratic Republic of the Congo.
  • The white eared Kob is found in Western Ethiopia and South Sudan (this is one of the main animals in the huge migration within sudan)
None are currently threatened with extinction. Their total population is 50,000-60,000

Red Lechwe

Red Lechwe

Red Lechewe is a species of antelope found in the south of eastern African. The red lechwe is native to Botswana, Zambia, southeastern Democratic Republic of the Congo, northeastern Namibia, and eastern Angola, especially in the Okavango Delta, Kafue Flats, and Bangweulu Wetlands. They are found in shallow water, and have a substance on their legs which allows them to run pretty fast. Total population is around 160,000

Four subspecies of the lechwe have been recognized

  • Common red lechwe (Gray, 1850) – Widely distributed in the wetlands of Zimbabwe, Botswana, Namibia and Zambia. (80,000)
  • Kafue Flats lechwe  (Haltenorth, 1963) – It is confined within the Kafue Flats (seasonally inundated flood-plain on the Kafue River, Zambia). (28,000)
  • Roberts’ lechwe  (Rothschild, 1907) – Formerly found in northeastern Zambia, now extinct. Also called the Kawambwa lechwe.
  • Black lechwe (Kobus leche smithemani(Lydekker, 1900) – Found in the Bangweulu region of Zambia. (50,000)

In addition, the Upemba lechwe (1000)  and the extinct Cape lechwe are also considered subspecies by some authorities. Although related and sharing the name “lechwe”, the Nile lechwe (below) is consistently recognized as a separate species.

Nile Lechwe

The Nile lechwe or Mrs Gray’s lechwe  is an endangered species of antelope found in swamps and grasslands in South Sudan and Ethiopia.

Nile lechwe can visually signal and vocalize to communicate with each other. They rear high in the air in front of their opponents and turn their heads to the side while displaying. Females are quite loud, making a toad-like croaking when moving. Known predators are humans, lions, crocodiles, cheetahs, wild dogs, hyenas and leopards. They flee to water if disturbed, but females defend their offspring from smaller predators by direct attack, mainly kicking. Nile lechwe are crepuscular, active in the early morning and late afternoon. They gather in herds of up to 50 females and one male or in smaller all-male herds. They divide themselves into three social groups: females and their new offspring, bachelor males, and mature males with territories. A males with territory sometimes allows a bachelor male into his territory to guard the region and not to copulate. They are sexually mature at 2.

Nile lechwe feed on succulent grasses and water plants. They have the special capability to wade in shallow waters and swim in deeper waters, and may feed on young leaves from trees and bushes, rearing up to reach this green vegetation. Nile lechwe are also found in marshy areas, where they eat aquatic plants.  Around 32,000 and are classed as endangered

The Nyala is a spiral horned species

 found in Southern Africa. The nyala is mainly active in the early morning and the late afternoon. It generally browses during the day if temperatures are 20–30 °C  and during the night in the rainy season. The nyala feeds upon foliage, fruits and grasses, and requires sufficient fresh water. It is a very shy animal, and prefers water holes to the river bank. Not territorial, they are very cautious creatures. They live in single-sex or mixed family groups of up to 10 individuals, but old males live alone. They inhabit thickets within dense and dry savanna woodlands. The main predators of the nyala are lion, leopard and African wild dog, while baboons and raptorial birds prey on juveniles. Males and females are sexually mature at 18 and 11–12 months of age respectively, though they are socially immature until five years old. They have one calf after 7 months of gestation. Its population is stable, with the greatest threat coming from habitat loss as humans expand. There are thought to be 36500 and the population is stable.

Waterbuck

The waterbuck  is a large antelope found widely in sub-Saharan Africa.It was first described by Irish naturalist William Ogilby in 1833.

Its 13 subspecies are grouped under two varieties: the common or ellipsiprymnus waterbuck and the defassa waterbuck. The head-and-body length is typically between 177 and 235cm  and the typical height is between 120 and 136cm. In this antelope, males are taller and heavier than females. Males reach roughly 127 cm at the shoulder, while females reach 119cm. Males typically weigh 198–262 kg and females 161–214 kg. Their coat colour varies from brown to grey. The long, spiral horns, present only on males, curve backward, then forward, and are 55–99 cm long. Waterbucks are rather sedentary in nature. As gregarious animals, they may form herds consisting of six to 30 individuals. These groups are either nursery herds with females and their offspring or bachelor herds. Males start showing territorial behaviour from the age of 5 years, but are most dominant from the six to nine. The waterbuck cannot tolerate dehydration in hot weather, and thus inhabits areas close to sources of water. Predominantly a grazer, the waterbuck is mostly found on grassland. In equatorial regions, breeding takes place throughout the year, but births are at their peak in the rainy season. The gestational period lasts 7–8 months, followed by the birth of a single calf.

Waterbucks inhabit scrub and savanna areas along rivers, lakes, and valleys. Due to their requirement for grasslands and water, waterbucks have a sparse ecotone distribution. The IUCN lists the waterbuck as being of least concern. More specifically, the common waterbuck is listed as of least concern. while the defassa waterbuck is near threatened. The population trend for both is downwards, especially that of the defassa, with large populations being eliminated from certain habitats because of poaching and human disturbance.

The common waterbuck is listed as least concern, while the Defassa is listed as near threatened. Only 60% of this subspecies population is in protected areas, so it could get worse, if they are lost.

Spinner Dolphin

Spinner dolphin

The spinner dolphin (also known as the long-snouted dolphin (distinguishing it from the Clymene dolphin – which is often called the short snouthed spinner dolphin) is a small dolphin found in off-shore tropical waters around the world. It is famous for its spinning  along its length, as it leaps from the water. It is a member of the family Delphinidae of toothed whales.

The four named subspecies are:

  • Eastern spinner dolphin, found from the tropical eastern Pacific.
  • Central American or Costa Rican spinner dolphin, also found in the tropical eastern Pacific.
  • Gray’s or Hawaiian spinner dolphin, from the central Pacific Ocean around Hawaii but represents a mixture of broadly similar subtypes found worldwide.
  • Dwarf spinner dolphin, first found in the Gulf of Thailand.

The species, though, displays greater variety than these subspecies might indicate. A hybrid form characterized by its white belly inhabits the eastern Pacific. Other less distinct groupings inhabit other oceans.The species name comes from the Latin word for “long-beaked.”

Spinner dolphins are small cetaceans with a slim build. Adults are 129–235 cm long and weigh 23–79 kg. This species has an elongated rostrum and a triangular or subtriangular dorsal fin. Spinner dolphins generally have three colours, one on the dorsal fin, one on the underside and one on the upper-side. Also, a dark band runs from the eye to the flipper, bordered above by a thin, light line. However, the spinner dolphin has more geographic variation in form and coloration than other cetaceans. In the open waters of eastern Pacific, dolphins have relatively small skulls with short rostra. A dwarf form of spinner dolphin occurs around southeast Asia. In these same subspecies, a dark dorsal cape dims their tripartite colour patterns Further offshore, subspecies tend to have a paler and less far-reaching cape.] In certain subspecies, some males may have upright fins that slant forward.[8] Some populations of spinner dolphin found in the eastern Pacific have backwards-facing dorsal fins, and males can have dorsal humps and upturned caudal flukes.

The spinner dolphin lives in nearly all tropical and subtropical waters between 40°N and 40°S. The species primarily inhabits coastal waters, islands, or banks. However, in the eastern tropical Pacific, spinner dolphins live far from shore. Some studies suggest they use different areas at different times of the year.

The spinner dolphin feeds mainly on small mesopelagic fish, squids, and sergestid shrimps, and will dive 200–300 m to feed on them. Spinner dolphins of Hawaii are nocturnal feeders and forage in deep scattering layers, which contain many species. The dwarf spinner dolphin may feed mostly on benthic fish in reefs and shallow water. Off Oahu, Hawaii, spinner dolphins forage at night and cooperatively herd their prey into highly dense patches. They swim around the prey in a circle and a pair may swim through the circle to make a catch. Spinner dolphins are in turn preyed on by sharks. Other possible predators include the killer whale, the false killer whale, the pygmy killer whale and the short-finned pilot whale. They are susceptible to parasites, and are known to exhibit both external ones like barnacles and remoras as well as internal parasites.


Due to the spinner dolphin foraging and feeding at night, in certain regions, such as Hawaii and northern Brazil, dolphins spend the daytime resting in shallow bays near deep water. Spinner dolphins rest as a single unit, moving back and forth slowly in a tight formation but just out of contact with one another. These resting behaviours are observed for about four to five hours daily. During rest periods, spinner dolphins rely on vision rather than echolocation. At dusk, they travel offshore to feed. They travel along the shore during foraging trips, and the individuals that occupy the same bay may change daily. Some individual dolphins do not always go to a bay to rest; however, in Hawaii, dolphins do seem to return to the same site each trip.

Spinner dolphins live in an open and loose social organization. The spinner dolphins of Hawaii live in family groups, but also have associations with others beyond their groups. Mothers and calves form strong social bonds. Spinner dolphins seem to have a promiscuous mating system, with individuals changing partners for up to some weeks. A dozen adult males may gather into coalitions. Vocalizations of spinner dolphins include whistles, which may be used to organize the school, burst-pulse signals, and echolocation clicks. The spinner dolphin has a 10-month gestation period, and mothers nurse their young for one to two years. Females are sexually mature at four to seven years, with three-year calving intervals, while males are sexually mature at seven to 10 years. Spinner dolphins live for about 20-25 years old. Breeding is seasonal, more so in certain regions than others.

Although most spinner dolphins are found in the deeper waters offshore of the islands, the rest of the Hawaiʻi population has a more coastal distribution. During daytime hours, the island-associated stocks of Hawaiian spinner dolphins seek sanctuary in nearshore waters, where they return to certain areas to socialize, rest, and nurture their young.

They get their name for their spinning jumps, a spinner dolphin comes out of the water front first and twists its body as it rises into the air. When it reaches its maximum height, the dolphin descends back into the water, landing on its side. A dolphin can make two to seven spins in one leap; the swimming and rotational speed of the dolphin as it spins underwater affects the number of spins it can do while airborne. These spins may serve several functions. Some of these functions are believed by experts to be acoustic signalling or communication. Another reason is to remove ectoparasites such as remoras. Dolphins may also make nose-outs, tail slaps, flips, head slaps, “salmon leaps”, and side and back slaps.

The protected status of spinner dolphins are CITES Appendix II and Marine Mammal Protection Act (MMPA) protected throughout its range as well as MMPA depleted in its eastern stock. Tens of thousands of spinner dolphins, mostly eastern and white-bellied varieties, were killed in the 30 years after purse seine fishing for tuna began in the 1950s; The process killed probably half of all eastern spinner dolphins. They have also been contaminated by pollutants such as DDT and PCBs. Spinner dolphins, as with other species affected by ETP tuna purse-seine fishing, are managed nationally by the coastal countries and internationally by the IATTC. The IATTC has imposed annual stock mortality limits on each purse seine and promulgated regulations regarding the safe release of dolphins. The eastern tropical Pacific and Southeast Asian populations of the spinner dolphin are listed on Appendix II of the Convention on the Conservation of Migratory Species of Wild Animals (CMS), since they have an unfavourable conservation status or would benefit significantly from international co-operation organized by tailored agreements. In addition, the spinner dolphin is covered by Memorandum of Understanding for the Conservation of Cetaceans and Their Habitats in the Pacific Islands Region (Pacific Cetaceans MoU) and the Memorandum of Understanding Concerning the Conservation of the Manatee and Small Cetaceans of Western Africa and Macaronesia (Western African Aquatic Mammals MoU). Spinner dolphins are susceptible to disease and two of the recorded diseases within them are toxoplasmosis and cetacean morbillivirus. The number of cases reported however is fairly low in the species.

Spinner dolphins in Hawaii receive multiple daily visits to their near-shore resting grounds, with boats taking people out daily to snorkel and interact with the local dolphin population. Such activities are increasingly coming under criticism on the grounds of possible harm to the dolphins, and efforts are being made both to educate the public in order to minimise human impact on the dolphins, and to bring in regulations to govern these activities. In 2023, 33 swimmers were arrested for reportedly harassing dolphins off the coast of the Big Island of Hawaii. The swimmers reportedly broke federal law by swimming within 45 meters (50 yards) of the dolphins. The ban went into effect in 2021 due to dolphins not getting enough rest during the day to forage for food at night. The swimmers were caught by drone footage pursuing the dolphins as they tried to escape.

We are eager to work with people who run boats to see these animals – provided they are run with due care for the animals. Do get in touch, or fill in a form you will find in ‘List your wild place’ at the top of the page (or click here).

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.

Agile Mangabey

Agile Mangabey

The agile mangabey is an Old World monkey of the white-eyelid mangabey group found in swampy forests of Central Africa in Equatorial Guinea, Cameroon, Gabon, Central African Republic, Republic of Congo, and DR Congo.

Until 1978, it was considered a subspecies of the Tana River mangabey. More recently, the golden-bellied mangabey  has been considered a separate species instead of a subspecies of the agile mangabey.

Similar to other mangabeys, they are active during the day. Although generally tree-living, they do spend a significant portion of their time (12–22%) on the ground, especially during the dry season. It is often heard first, and males have a loud, species-specific call that is believed to be used to space themselves out – in a similar way that wolves operate with howls. Other calls are also used to maintain group cohesion and warn of predators. Group size can be as high as 18 members, led by a single dominant male. Group meetings can be friendly and may involve exchange of members.

Adult males not in groups often travel singly.

Fruit makes up a major portion of the agile mangabey diet. They are known to eat at least 42 different species of fruit. Their tooth structure and powerful jaws allows them to open tough pods and fruits that many other monkeys can not access. Agile mangabeys eat from a number of dominant swamp-forest trees, including Irvingia, Sugar plums when they are fruiting. They also eat fresh leaf shoots from Raffia palm when fruits are scarce. Grass and mushrooms, Invertebrates, bird’s eggs and some vertebrate prey, such as rodents.

Primate family tree main and great and lesser apes

Primate family tree

The primates are in some ways one of the most successful families. It is true that many are now endangered, however, unfortunately, that is as a result of the run-away success of the most successful member of the primate family us! Having left the rainforests behind, we have been reducing their coverage dramatically over the last few centuries. 

The sad thing, is that while we have pushed many of our closest cousins towards extinction, the loss of forests may well cost us dearly in the future as well. As a species, we need to pull together to meet this challenge. in order to jump to the various families, click on the family of interest above – though all can also be reached by scrolling down.

Great Apes

Great ape Family split is thought to have split from its nearest relative – the gibbon family, around 17 million years ago.

4 million years later the Orangutan family split from the gorilla line and the human/chimp line.

3 million years after this (so around 10 million years ago) the gorilla family split from the Homo (humans) and Pan

Finally the human line (homo) split from the Pan line 5-6 million years ago.

It should be noted, that chimpanzees and Bonobos split from a common ancestor just 1.8 million years ago. This occurred as the two populations ceased to be able to have contact with each other – the Congo rive formed between 1.5 and 2 million years ago.

It should be noted that while I have grouped eastern western and skywalker gibbon together, there is some contention that the skywalker gibbon should be in its own genus, having diverged around half a million years aog

Bowhead whale

Bowhead whale

Also known as Greenland right whale, Arctic whale, steeple-top, and polar whale, they are closely related to the right whales, the bowhead whale looks quite different. It is in a different genus to the other right whales (so is a more distant relation.

The only whale that is endemic to the Arctic and sub-arctic, its mouth is a third of the size of the body. They are incredible long lived often living to 200 years old. They have incredibly thick skulls, which allows them to use their heads to break through the arctic ice.

Unfortunately, they were an early target of whalers, and so in 1966 hunting of them was banned. They have recovered to the point where out of the 5 subpopulations, 3 are endangered, one is vulnerable and the last one currently classed as low risk. Another unfortunate effect of whaling, was to put an end to the summer habits of the bowhead whale – before whaling, it appears that different whale populations would cross seas during the summer, and interbreed.

  1. The Western Arctic stock in the Bering, Chukchi, and Beaufort Seas estimated at 12,500 (though with 95% confidence range 8000-19500         
  2. The Hudson Bay and Foxe Basin stock estimated at 345 with a high confidence
  3. the Baffin Bay and Davis Strait stock which is estimated at over 1000 individuals
  4. the Sea of Okhotsk stock contains only 100-200
  5.  The Svalbard-Barents Sea stock was hunted to near extinction. As such while I cannot find a number, it is unlikely to have a large population
