Whales, Dolphins and Porpoises family tree

Cetaceans -Whales, porpoise and dolphins

Few people can avoid stopping to watch, if they spot cetaceans from a cliff. While the family is wide and varied, they are all pretty interesting. From some of the largest and most intelligent hunters such as killer whales to the largest animal on earth the blue whale.

Whale and dolphin watching tourism is worth a lot of money – this can be essential, as in many places the extra money helps a community survive. 

I hope, overtime, to make this section of the website as large a list of places to view cetaceans and people who will help you in that quest.

As might perhaps be suspected, all of the mammal species which have returned permanently to the sea, and developed breathing holes located on their back (and therefore perfectly placed for taking quick breaths) are  related.

So what is the most closely related living land mammal? Perhaps obviously, it is a species which spends much time in the water – the hippopotamus.

As with all of these pages, as we create pages for each individual species, they will be linked to the photo below.

So the baleen whales are split into three families, these are not large as there are only 16 species of baleen whales in the world. At the current time, there are roughly 1.1 million baleen whales in the worlds oceans

Below is a family tree of the group

 

Baleen Whales

Baleenideae – the rhight whales

 

The first  living split is Baleenidae, this family is not huge. The north atlantic and north pacific are closest related, these species are closely related to the Southern pacific right whales. Their name is unfortunate – it is called right whale for 3 reasons, it swims slowly, floats when dead and carries a large amount of oil. This lead to all these species being hunted close to extinction.

The other family is called Balaenopteroidea. Here species peel off slowly. I will list them in the order that they split.

The first split is the minke whale – of which there are 2 species, the common and southern minke whale, with the grey whale being the next most similar.

The next are the humpback whale and the fin whale followed by the Blue whale.

The last group of whales are from a group called the Brydes whales complex

This completes the list of baleen whales. The other branch of the Cetaceans is known as the toothed whales

Toothed Whale

.I am going to look at them in 3 groups, though the third is not particularly closely related to each other

  • Delphinoidea: This includes
    • Monodontidaes – Belugas and narwhals
    • Phocoenidae – The family of Porpoises (7 species) such as harbour porpoises and Vanquita

 

    • Delphininidae – these are the oceanic dolphins – 37 species split into several subfamilies which we will deal with one by one.
Subfamily Delphininae – 15 species (tamanend bottle nose dolphin only recognized as separate species, will build page for it at some point when photos are readily available.

Subfamily  Globcephalinae 11 species

Subfamily incerta sedis (latin for “of uncertain placement” )6 species

Subfamily Lissodelphininae 6 sppecies

Subfamily Orcininae

  • Inioidea : This includes 3 groups
    • Iniidae (only 1 of 5 genus remains -Inea (4 species: Araguaian river dolphin, Bolivian river dolphin  and Orinoco dolphin)
    • Lipotidae: which contains only one species: the Baiji or Chinese river dolphin
  • Pontoporiidae: which contains one species 

The next family is the beaked whales. There are 24 species, of which only 3-4 have been well studied. This is because they spend much of their time deep in the sea, it appears that each species does not have many members and they are incredibly reclusive in their habits.

One might ask how an air breathing animal can spend so much of its time deep in the ocean? Well the Curved beaked whale has had a dive timed at 138 minutes. More incredible, they only need around 2 minutes to catch their breathe before sinking back into the depths. This means that if required, they can spend just 20 minutes out of 24 hours at the surface – an incredible stunt.

There appear to be a great number of species that are extinct – these we will not list, but will mention each subfamily in passing.

Incertae sedis contains 5 extinct genus, Basal forms include 13 extinct genus

Subfamily Berardiinae contains 3 genus, 2 of which are extinct, but the third contains 3 living species (and one dead) .  

Genus Beradius

 

Next we cover the Bottlenose whales

Northern                                                                                                                     Southern and                                                        Tropical

Subfamily Ziphiinae  contains 5 genus, 3 are extinct, but two have just one species in each

Genus Tasmacetus: Shepherds beaked whale Genus Ziphius: Cuviers beaked whale

As you can see from the whale family tree, the sperm whales are separate from the rest. However, they are toothed whales so belong in this section of the page.

Crocodilians

Crocodilians

Crocodilians are a family of species found in the Tropics of the Americas, Africa Asia and Australia. They live in or near water – rivers, lakes, wetlands and even salt water.

Generally, they are apex predators in their ecosystems with no natural predators. Having said this, as with every species, humans hunt them, and in many places this has pushed them close to the brink of  extinction.

In the current age, there are 24 species, spread across 3 families and 8 genus.  We also have a photo gallery with many ways to filter the crocodilians and this is at the bottom of the page click here to jump to it

 

So taking the genus in order

Caimenae is the sub-family, sitting below Aligatoridae (Alligatoridae being one of two clades in Crocodilia_. There are 3 genus

Caimen – A line of crocodilians that inhabit central and south America,

Melanosuchus  The black caimen is the only known living species from this Genus, and is found throughout the Amazon basin

Paleosuchus is a south American group of Caimen 

The only other family below Alligatoridae, is the subfamily of Alligatorinae.

This includes only two species 

American Alligator                                                                                                                                  Chinese Aligator

 

Longirostres is the other clade to make up the Crocodilia family. The first sub- family is Crocodylidae

This contains 3 genus with the first being Crocodylus which is the family of true crocodiles.

This includes 14 living species as well as 5 known only from fossils (we will not discuss these fossil specimens in this page)

The second genus is Mecistops which is the slender snouted crocodiles, with only 2 species

The last (third) genus is Osteolemus

The other sub -family is Gavialidae which includes 2 genus includes Gaviolis and Tomistona. Which we will deal with together as each only has one living species.

Elephant

African Savannah elephant, Asiatic elephant and Africa forest elephant

Elephant family tree

African Savannah African forest, and Asian Elephant

There are 3 species of elephant in the world (these come from two closely related genera, Loxodonta (the African elephant genus, and Elephas the Asian elephant genus, both are dealt with on this page). They are a good indicator species, as if an area is capable of supporting elephants, it can probably support most other species as well (those above are in the same order, should you not recognize them). 

The African Savannah elephant (left) and African Forest Elephant elephant (right) are both part of the same genus – Loxodonta. The Asian elephant (only one species, though a 3 subspecies Sri Lankan elephant, Mainland Asian elephant and Sumatran Elephant) is the only  member of the genus Elephas. It is important to remember, that while the mammoth is a well known extinct species like the Elephant, it is estimated that there have been 180 different elephantine species in earths history.

Click on the one you are interested below, to find out more (along with seeing longer videos on each separate species), or scroll down to read all the articles we have written on elephants.

[smart_post_show id="15245"]

We already have a number of places to view wild savannah elephants. Click on wild places or here, for all our savannah destinations in Africa. All the savannahs have elephants, Except the mountain gorilla reserve, which has forest elephants – often seen on a walk in this reserve.

Should you work in tourism or conservation, and would like to list another destination, either of this species of elephant, or indeed of African forest elephants or Asian elephants, you will find a link at the top of the main page “list your wild place” or alternatively click here.

Nocturnal mammals

In the future, there will be a page attached to each image, and we also aim to include nocturnal mammals from around the world. This page is largely aimed at incectivores and other species that would not fit into onther categories.

We aim to add far more over time, but you will find others in other families, for instance the Hyena family.

Moschidae family and the Muntjacs

Had all of the species found in this family been alive, this family would have been around 3 times larger. The only family that is still alive is the Musk deer.

There are 12 Muntjac species. Now hopefully, at some point the amount of news and information on each species will warrant a different page for each species. However, until that time, there will just be one page (this one).

Muntjac are an ancient species, having first appeared 15-35 million years ago. What is more, fossils from this period show that Muntjac once lived in Europe, with fossil deposits found in France, Germany and Poland.

This perhaps explains how easily this species has become an invasive species. In parts of the UK, they are the most common deer species to see. Indeed, some of the subspecies are more common outside their natural range than in. Below I will deal with each species in turn. As I say above, should any of these sub-articles get big enough, I will move them off the page. Where ever the information is, you will be able to reach each species information by clicking on its photo

Borneon Yellow Muntjac: endemic (only found in) to the rainforests of Borneo. There is another muntjac species that is found in Borneo the Southern red muntjac, or the common muntjac (this will be dealt with on its own page). It has small horns, only 7 cm long, and is smaller than the common muntjac. Its yellow back also helps differentiate it. Never-the-less, it was only recognized as a separate species in 1982, and there has not been much study done in it since.

Its conservation status is considered least concern, though the population is decreasing. Having said this, given the lack of dedicated study, we do not really know what is going on.

Fea’s Muntjac: Found in southern Myanmar and Thailand, it is considered rare. It has a similar size to the common muntjac, and inhabits upland evergreen, mixed or shrub forest. It takes its name from a zoologist Leonard Fea. It is found in the Tenasserin hillls, that lie along the border between of the two countries.

Its conservation status is considered endangered

Giant Muntjac: also known as the large-antlered muntjac. It was discovered in 1994, in Loas and Vietnam. 38 specimens were caught analysed and rereleased. As a result of slash-and-burn agriculture along with hunting.. They share their home with Leopards and Tigers, so there is a certain amount of natural predation that goes on. 

Its conservation status is critically endangered

Gonshan Muntjac: 

Found in Southeast Tibet, Northeast India and Myanmar. They are regularly hunted, which could threaten their survival. Having said this, while they have not been successful in getting an accurate count, they are regularly encountered, which suggests that they are not endangered.  Khakaborazi National Park and the Hponkanrazi Wildlife Sanctuary are two reserves where their population is good. 

Not currently considered endangered.

 

Hairy fronted (or black fronted ) Muntjac: 

Found in 3 provinces in China, there are some questions as to whether this is the same species as the Gonshon Muntjac.

It is considered endangered with just 5000-10,000 left in the wild. It was considered highly endangered as early as 1975, only being known from a few museum specimens. In 1990 it was thought to have 10,000 individuals, but recent assessments suggest a current population of around 7000.

Leaf Muntjac: 

Discovered by Alan Rabinowitz in 1997 when examining the carcass of a small deer – initially thinking it was the juvenile of another species he realized it was an adult. It is found in Myanmar and India. It is found at heights of 450-600m which is the transition from tropical to temperate forests.

Conservation status is data deficient, but continued hunting would suggest that the population is falling whatever level it is.

Red Muntjac or Southern red Muntjac: 

Until recently, thought to be the same species as the Indian and the Common Muntjac. It is an omnivore, eating fruit, shoots, grass and seeds, alongside birds eggs, small animals and carrion.

It is considered least concern

Northern red Muntjac: 

Found across many countries in South central and South-Eastern Asia. There are still several subspecies, though it was until recently thought to be the same species as the Southern Red Muntjac.

It is considered least concern, and appears to cope with high hunting pressures as well as changes in its home due to climate change.

Pu hoat Muntjac: 

Only found in the Pu Hoat region of Vietnam, close to Laos, it has only been recorded once, and is thought to be similar to the Roosevelt Muntjac.

Reeves or Chinese Muntjac: 

Found in Southern China and Taiwan, it has been introduced to United Kingdom, Ireland, the Netherlands, Belgium, and Japan. It was discovered by John Reeves in the 18th century. It feeds on all forms of plant, and will eat bark. It is also known to eat birds eggs and carrion if it gets the chance. It is included on a list of species that cannot be imported into the EU due to the threat it can cause. In 2008 Reeves Muntjac was estimated to have a UK population of over 100,000.

It is considered least concern it its home country, and is quite common 

Roosevelt Muntjac: 

A single specimen was presented to the field museum after a trip organised by Theodore Junior. 

Many consider it a subspecies of the Fey Muntjac, and has officially been extinct since 1929 – though there have been sightings in Northeast Laos and close by in Vientam. A camera trap in Xuan Lien Nature Reserve in Vietnam appear to have identified two individuals, which suggests that it cannot be extinct.

Truong Son Muntjac:

Found in the Truong Son mountains, it was only discovered in 1997.

It is considered data deficient in terms of deciding its status.

Ruminenta

These are hoofed grazing or browsing mammals. It includes around 200 living species as well as numerous extinct species. Ruminants are split into 2 rather lopsided families. Trevlotain (which are water Chevrotain) split first. The rest lie in the family Pecora. As such, you will find this family tree lower down the page.

The first family is Tragulina is an infraorder of even-toed ungulates. It contains just one Genus Tragulidae and this contains just one group of species the Chevrotains and mouse-deer. This is the only Ruminant family, which is not in the Pecora family

Every other part of this family falls in the tribe Pecora

Giraffidae

The Okapi is the lesser known cousin of the Giraffe

Once a diverse group that was found through Africa and Asia, there are only 2 species most people would recognize, that survived to the modern age. These are the Giraffe and Okapi, though in actual fact, there are actually 4 different species of giraffe that survive (as well as the 8 subspecies.

The living Giraffe species are:

 It should be noted that the IUCN does not recognize the multiple species, however, the Giraffe Conservation Foundation (GCF), together with its partner Senckenberg Biodiversity and Climate Research Centre (BiK-F), has performed the first-ever comprehensive DNA sampling and analysis (genomic, nuclear and mitochondrial) of all major natural populations of giraffe throughout their range in Africa. As a result, the layout of the species and subspecies that I have given has been recognized.

Please note that the general news below is all of the news about all species of giraffe. To see any posts about Okapi, visit the Okapi page by clicking on it above.

Cervidae

Cervidae family (deer) here red deer

Cervidae (the deer family)

Cervidae is the family of deer. It is a close relation of Bovidae, which includes antelopes and giraffe.

There are 2 branches of this family Cervinae (Old World deer) and Capreolinae  (New World  deer). They will be linked from the images.

The first tribe in Cervini is Munticini

Munticini includes just 2 genus

Genus Elaphodus contains just one species, that of the Tufted deer

 

The other (2nd) tribe is Cervini (true deers) and includes 7 genus some of these only have a few species so will be dealt with together.

In the first group we will include:

Genus Ruserus (1 species), Genus Panolia (1 species), Genus Elaphurus (1 species), Geuns Dama (2 species) in that order.

and now just one genus on each set

Genus Axis

Genus Cervus

Gens Rusa

Capreolinae  which is the new world sub-family of deer. This includes 3 tribes of deer

Tribe Capreolini which includes 2 genus

Genus Capreolus (2 species) and Genus Hydropotes  (1 species) (pictures in this order)

Also Tribe Alcenini which includes one Genus Alces with just one speices – the elk

I should note, that while the deer below this point may well get their own page in time, for now, they will have a little information added to their title popup.

 

The last tribe is Tribe Odocoileini which includes 7 genus

I will deal with these 7 genus in two blocks

In the first block:

Genus: Blastocerus 1 (species), Hippocamelus 2, Odocoileus 3, Ozotoceros 1, Pudu 2 and Rangifer 1

Last genus is genus Mazama, the Brocket family. Brocket, any of several small deer constituting the genus Mazama of the family Cervidae, and found from Mexico to South America. Timid browsers, brockets inhabit wooded areas and generally live alone or in pairs.

Musk deer are similar to cervids in many respects and as such are often classified as a subfamily of the Cervidae. However, they are not. They differ in several ways, but particularly, in that both sexes lack antlers (the male has a huge, scimitar-like canine instead; females have smaller canines). They have a single opening to their lacrimal canals, versus 2 in cervids.

Bovini family or wild cattle

Bovini or the family of all wild cattle species

Bovinae is a biological family of cloven hooved family Each of these three tribes encompass a variety of species and we will deal with these tribes one by one. The Bovinae family includes all bovids, which are ruminant mammals (cloven hooved) which include all of the worlds cattle, yaks, bison, buffalo antelopes (which include goat-antelope) goats and sheep. 

This family currently has 143 surviving species, with 300 known species. it has 11 major families and 13 major tribes.

This family first appeared 20 million years ago. Below is the initial splits into 3 in this family. It should be noted that not all these families will be relevant at the current time – but as destinations grow all should be fully relevant. 

 

So, firstly Borselaphini, this consists of just 2 species, the Nilgai and the 4-horned 

The next tribe (below) is Bovini, which includes 3 families. These vary in size quite widely with the middle one only containing one species

The first family Bubalina contains 2 Genus Syncerus only contains one species (first) the rest are from Bubalina

              Genus Syncerus                                                              Genus Bubalus

 

The second family contains one genus psuedorygina which contains one species the Saola

Bovina contains 1 Bison subgenus (it used to contain 2 but the Genus Bos became a subgenus (it should be noted there are far more subgenus that are extinct). Also, for simplicity sake, any subspecies will only be mentioned in each species page.

   Subgenus Bos                        poephagus                                Bison & Bos                               Bibos

Bos is domestic cattle

_Taurus originate in Africa,  _Mutus=wild Yak,                           Bos_Indicus                                                                                                Domestic cattle                            Originate in Himilayas               Originate in India, fatty hump (first on second row)                                and Aurochs                                     

Finally tribe Tragelaphini or spiral horned antelope contains 5 genus. The first 4 contain 1 species (in order) the last genus has 3 species. If I cover subspecies these will be in their own pages

Genus Ammelaphus           Genus Nyala                                                        Genus Tragelaphus                        Genus Taurotragus             Genus Strepsiceros

Bovidae family (including Aegodontia &Boodontia & Caprinae) or Antelope family tree

Bovidae family (including Aegodontia &Boodontia) or Antelope family tree

Antelope lie in the Bovidae family, and account for around 2/3 of the 135 Bovidae species that exist in the world. It should be noted that deer come from the family Cervidae, which means that despite looking extremely similar, antelope are more closely related to cattle than they are to deer.

There are 91 antelope species in the world with 72 found in Africa, 14 in Asia, with the last 5 found in Eastern Europe.

There are 8 subfamilies in Africa

1. Subfamily Bovinae

Spiral horned antelopes made up of tribe Tragelaphini: 9 species 4 subspecies.

2. Subfamily Reduncinae

Rhebok, reedbucks, and waterbucks 8 Species, 11 Subspecies

3. Subfamily Peleinae:

 1 Species
 

4. Subfamily Alcelaphinae

 

Sassabies, hartebeests, and wildebeests: 6 Species (depending on how you count, it can be anywhere from 6 to 10) , 19 Subspecies

5. Subfamily Hippotraginae

Grazing antelope: 7 Species, 4 Subspecies

6. Subfamily Aepycerotinae

Impala: 1 Species which is impala, 2 Subspecies

8. Subfamily Cephalophinae

 Duiker: 17 Species, 7 Subspecies

Caprinae

The Caprinae family is a close relation of Alcelaphinae & Hippotraginae (subfamily 4 and 5 on this page) but this family consists of the worlds goats and sheep.

This consists of 9 genus with just 1 species in each (and one further extinct so not included here) and then 5 genus with more than that. 

Firstly dealing with each genus with only one species.

Next the Capra genus, which consists of the worlds Ibex species

Next the Ovis family (sheep species)

Two species of Chamois remain

The second last group is the Serow (6 species)

The last group is the Goral
