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.

For more information on each species, click on their photo and this will take you to their page

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

Gibbons

Dhole

Dhole

The Dhole is an ancient species of dog, It split from the rest of the dog family 5.2-7.6 million years ago.

While it is related to the family of canis, it is different. It was once found throughout Europe, Asia and North America, but its range decreased down to its current range 12,000-18,000 years ago. In more recent times, this area has shrunk significantly, as a result of human changes.

Even with the dramatic reduction in range, it is still a large area, given the current population is thought to be around 2500 individuals, which means that it has to be a rare species, and likely there are areas with little or none of the species still found.

There are a variety of factors, from loss of habitat, persecution for livestock predation, competition from other species and diseases caught from closely related species. There are currently 7 subspecies of dhole recognized, though in the past that number has been as high as 10.

It is protected in parts of its range, but is still at threat.

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. Below this, I will list any opportunities to see this species in the wild. Click on list your wild place, to list yours.

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.

Nocturnal mammals

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.
