Pangolin Family – Manoidea

Pangolins or the family Manidae

Pangolins are a strange group of animals. There is little other animals that look like them. Oddly, they are in the same supergroup as Bears dogs cats and other carnivores, though given that they eat insects they are carnivores. Indeed, in the past there was an order Insectivora, however this order has been abandoned, as it turns out some insect-eaters are not closely related (indeed, while often looking similar it appears that this is generally a case of convergent evolution – i.e. similar habits and similar requirements requiring the same body parts, so you end up with a similar animal.

Anyway, in this instance, it is not surprising, as all of the pangolins are part of the same tribe – sister genera essentially. There are quite a few ” cousins” species at one point but all these have gone. I would hope, that at some point people would stop believing that Keratin (a pangolin scales is made of the same substance as human nails, yet while chewing your own nails is seen as bad manners, for some reason pangolin scales, like items like rhino horn, are claimed to be able to cure everything from headache to erectile difficulties. Of course, there is no scientific case for this belief, but that has not stopped the price of these scales has reached $3000 dollars per kg, with an animal holding about half a kg (the most scaly is the Philippines pangolin, which holds almost a kg – this is the equivalent of almost a year of a local salary, unfortunately making it well worth it, to spend months looking for this rare animal)

The Manidae (in ancient roman religions this was meaning spirits- chthonic deities of deceased loved ones )  includes 3 genera.

Manis contains all of the surviving Asian Pangolins known as the Asian Clade, though the last 3 are in Subgenus: Paramanis – southeast asian pangolins

Please note, I have not included Manis .sp which is a proposed fifth Asiatic species of this family, and this is still a long way from being confirmed.

Due to their cryptic nature, and current hunting pressures, there is little tourism around these species, and little likelihood of any in the near future. As such, while I would like to separate these species out into their own pages, it is unlikely to ever be necessary within the scopes of this website. Having said this, I am looking for partners, should anyone be working with tourism of these species, do get in touch through the link at the top of the page – we can mask the location, but are keen to help give living pangolins a worth as soon as possible.

Below is a list of each species, with a video of them. We hope to add links to go see them, and support their long-term future, we will have to see if tourism of these strange animals every takes off.

Chinese Pangolin

The Chinese pangolin is listed as critically endangered, having had an 80% decline in its population in 21 years (or 3 generations). Its threat is poaching for the illegal wildlife trade.

It is thought that at most 10,000 remain now. Given the huge number poached from elsewhere each year, it is highly unlikely that poaching for this species has stopped. They may well be hunted into extinction in the near future.

Indian (thick tailed) pangolin

The Indian pangolin (also known as >thick-tailed pangolin and scaly anteater) is a species found on the Indian subcontinent. It is listed as endangered, and CITES appendix 1

The size of the population is unclear (generally all estimates are very vague as they are usually secretive nocturnal animals rarely seen by humans

Philippine (Palawan) Pangolin

The Philippine pangolin (also known as the Palawan Pangolin) is only found in the Palawan district. Its habitat includes primary and secondary forests, as well as the grasslands that surround it.

It is listed as critically endangered by the IUCN, though with no idea of the former population, and no idea of the current one, it is hard to have any idea. People estimate that the population has fallen by 95% in the last 40 years.

Sunda (Malayan or Javan) Pangolin

The Sunda Pangolin (also known as Malayan & Javan pangolin) is found throughout Southeast Asia, including Myanmar, Thailand, Cambodia, Laos, Malaysia, Singapore, Vietnam, and the islands of Borneo, Java, Sumatra and the Lesser Sunda-Islands. It lives in forests (including plantations) and spends much time in trees.

It is listed as critically endangered, with a  further 80% decline expected in the next 20 years unless something changes. Positive news, is that unlike elsewhere, where locals don’t see pangolins anymore (because there are so few) here they are still seen. The video is a rescued baby of this species.

In the African Clade, there are 2 subfamilies each containing 1 genus, and each containing two living members 

                 Smutsiinae (large african pangolins )                                                                                                             Phatagininae (Smalll african pangolins)                                                         Genus: Smutsia  (African ground pangolin)                                                                                                    Genus: Phataginus  (African tree pangolin) 

Giant pangolin

Found from west Africa to Uganda, it weighs 30-40kg and can grow to 1.8m long (including the tail, which is almost as long as its body). It is found in savannah, forest and rainforest, anywhere with large termite populations and a source of water.

They are threatened by foolish beliefs about the medicinal value of pangolin scales – education does help, and much work is being done to deal with the demand in Asia. Demand has dropped dramatically in China, though places like Vietnam have recently developed a desire for similar things.

The penalty needs to be huge, in order to stop the slaughter before we loose these unique species.

The giant pangolin is CITES appendix 1, meaning all trade is banned. It is thought to be extinct in Rwanda. Part of the problem with trying to conserve a species like this, is that it is so hard to see in the wild – without expertise, you could share land with large numbers of pangolins and never see one – as such estimates of the size of the population are hard to come by.

Ground (Temminck) pangolin

Found throughout Southern and Eastern Africa, the ground pangolin has a length between 56cm and 1.6m, with the tail measuring up to 70cm.

It is also known as the Temmink pangolin. They are classed as vulnerable, and prefer savannah woodland, with plenty of scrub. It is given a vulnerable rating, as it has declined by more than 10% in the last 9 years and are expected to have declined by a further 30% or so in the next 18 years – a decline of 30-40% over 3 generations is the definition.

While conservative estimates, suggest that just 10,000 are trafficked each year, a more reasonable estimate would be 250,000 ever 2 years, or more than 10 times the original estimate.

Unfortunately, being shy and nocturnal, it is rarely seen making it very hard to know how many are left in the wild. This obviously makes it hard to know which areas have healthy populations, and which have been poached out.

We need to do better. Finding more out about this fascinating animal (and assuming we can end the poaching) these weird creatures might be capable of providing large tourism income, even in relatively small reserves. Having a density (in good parts of South African lowveld) of as high as 0.12km squared (0.3 per square mile). While this is low, it does suggest that even a small reserve might have 100 of these animals.

Long-tailed (black bellied) pangolin

Also known as the black-bellied pangolin, its name comes from its appearance. It has a long tail, and black hair on its stomach.

It is usually 30-40cm long with a tail 60-70cm, and generally weights between 2 and 2.5kg. The tip of this species tail is bare, and slightly prehensile, allowing it to feel around and hold onto branches as the animal works its way around the treetops.

Interestingly, unlike other pangolin species this one is diurnal or active during the day (though this may be an adaption to not be in competition with the tree pangolin, which shares a similar range). They communicate with other individuals through scent. Found in moist, tropical riverine and swamp forest environmentsthey have been found in partially cleared forests bush, as well as farm-land, generally former lowland rain forests. They are almost exclusively found in trees, and at that, high in the forest canopy. They prefer to live deep in the interior part of the forests, avoiding areas too near the outside.. They are capable swimmers, and are usually found near water, often dropping off branches into the water below.

Their scales have become relatively good camouflage, as well as an extremely good defence mechanism (not only does a predator find it hard to get inside, once it has rolled up, but each scale can also be sharp. 

Given their ability to live in disturbed habitat, it is really only the poaching that threatens this species.

Tree (white bellied) pangolin

Also known as the white bellied pangolin, or the three-cusped pangolin, they are more common than the long-tailed pangolin. Measuring 33-43cm long, with a tail 49-62cm, they are smaller than some of the other species. There are 2 recognized subspecies, one confined to Uganda and another everywhere else.

Also relatively tolerant of changes to the environment, they can do reasonably well on plantations. It is the most common pangolin found as bushmeat, and its population is thought to have declined 20-25% between 1993 and 2008 (3 generations). As a result, its conservation status has moved from least concern in 1996 to becoming officially endangered in 2019. 

Further rare footage of a Pangolin (and an aardvark) looking for food, from the BBC documentary 7 worlds one planet. We will add links to go and see each of these as we get them. They will appear at the bottom of the page

All rhino species of the world

Rhino have been hit hard in the last few decades. These species are all of the currently surviving species of wild rhino. Indeed, no species of rhino have been lost in modern times – in recent times the woolly rhino was lost. Further back, there are dozens of rhino species which are only known from fossils, with as many as 45-50 different species in the Americas alone.

There are links for the black and white rhino species, as these are found in the savannah ecosystems that we have listed, however, we will add more over time as we make contact with people in the field.

Gibbon – Silvery

Silvery gibbon

A wild silvery gibbon

Silvery gibbons are found in the island of Java. They are very endangered, and people in the country need increased reason to support their continued existence. It is true that in many places on earth where it is less of a struggle to survive and feed your family, protecting this primate would be of higher importance. We need to make this primates survival important for the people who live nearby, by giving a financial relevance. We can do this in 2 ways, the first is directly – making sure that conservation charities in the country are well resourced, and by giving money to those which engage locals and make sure that it is financially an incentive for the gibbon to survive. The other way, is through ecotourism – by travelling to visit Java, and to see the Javan rhino, we can make sure that locals see a direct link between the survival of the gibbon and their own wellbeing – Java lost their Orangutans a very long time ago, as well as their tiger in recent times, there is still a chance for Java to save what is left but they must act now.

 

It was listed as 2500, in 2008, it is unclear what has happened during the intervening 15 years, but its most recent assessment (in 2008) suggests that it had a likelihood of 50% of being extinct within a decade.

 

I suppose that we should feel pleased that we still have a chance. It is estimated that there are 8 viable populations of these gibbons, which add up to 2000, the largest of which is Mount Halimun Salak National park which sustains around 1000 in this single area. Other large populations of several hundred are found in Gunung Ciremai National park and Gunung Gede Pangrango national park. There are also about 12 reserves with non-viable populations. By treating these reserves as one mega reserve, and translocating these gibbons around so as to have one mega population, all these reserves could maintain healthy populations.

 

 Given the fact that the Javan Orangutan is extinct, it is well worth working on saving this gibbon, as it can help them build more ecotourism travel to Java. While these animals are not great apes, they are lesser apes, and are very interesting to watch. There are likely to be a great draw in places where Orangutans do not exist, such as on mainland Asia, as well as in smaller reserves that cannot support Orangutans.

 

This is not a species that I have written about, but as I do in the future, it will appear below. Furthermore, as we add destinations that are good for this species they will appear below the news.

The Borneon white cheeked gibbon, which lives in Borneo has been shown to be closely related (it was until recently considered a subspecies) so will be covered on this page. At the current time, the Borneon white cheeked gibbon is one of the most secure primate species, with over 100,000 remaining in the wild.

 

Gibbon – Pileated

Pileated Gibbon

This Pileated Gibbon is in a rescue centre, and is hopefully able to return to the wild.
Pileated gibbons live in the forests of Thailand, Western Cambodia and South -Western Laos.

There are currently around 35,000 in Cambodia in the wild, with another 30,000 in Thailand

 

 

While these animals are not great apes, they are lesser apes, and are very interesting to watch. There are likely to be a great draw in places where Orangutans do not exist, such as on mainland Asia, as well as in smaller reserves that cannot support Orangutans.

Gibbon – Northern buffed gibbon

Northern Buffed-cheeked gibbon

This is a newly discovered crested gibbon species which is found inVietnam, Cambodia and Laos. Its habitat is in the humid subtropical and seasonal tropical forests of these countries. 

Northern buffed gibbon

As they are newly discovered, little work has gone into understanding much about them. They are classed as endangered, but they are also known to be decreasing in the wild. It was only discovered in 2010.

 

Interestingly, the scientists first identified this as a new species by its very different song to other gibbons. Unfortunately, while I can see no evidence of a more recent survey, an estimate from 2011 suggested that this new crested gibbon population would be similar to other crested gibbon species, which number around 200. I hope to write on this species in the near future.

 

This is not a species that I have written about, but if I do in the future, it will appear below. Furthermore, as we add destinations that are good for this species they will appear below the news

 

Gibbon – Lar (also known as White handed) gibbon

Lar gibbons are quite attractive animals. The males and females are different colours.

Lar Gibbon

The Lar gibbon (which is known as the white handed gibbon in some areas). Currently found from Indonesia, Laos, Malaysia, Myanmar and Thailand. It is also present in the northwest portion of the island of Sumatra. This does give it the largest north south range of any gibbon species. However (as many would expect) that they once had a larger range. Their range historically extended from southwest China to Thailand and Burma. They were also found through the Malay Peninsula in primary and secondary tropical rain forests.  Lar gibbons are likely extinct in China, but if they still exist, they would only be found in southwest Yunnan, their former range.

There are five subspecies of lar gibbon:

  • Malaysian lar gibbon (H. l. lar) 15,000-20,000 
  • Carpenter’s lar gibbon (H. l. carpenteri)
  • Central lar gibbon (H. l. entelloides)
  • Sumatran lar gibbon (H. l. vestitus)
  • Yunnan lar gibbon (H. l. yunnanensis) (possibly extinct, if not under several 10)

 

 

This is not a species that I have written about, but if I do in the future, it will appear below. Furthermore, as we add destinations that are good for this species they will appear below the news

 

Gibbon – Kloss gibbon

Kloss gibbon

Kloss gibbons (also known as Mentawai gibbon, the bilou or the dwarf siamang). It is all black though smaller than the Siamang, also lacking the Siamang throats pouch. It is hard to tell the difference between males and females. Kloss’s gibbon exclusively lives on the “Mentawai Islands” that lie to the west of Sumatra. This island chain consists of 4 islands. The islands have large areas of rainforest, and this is where the Kloss gibbon spends its time. Pairs live in exclusive areas of 20-30 hectares, which it defends aggressively against other gibbons.

This is not a species that I have written about, but if I do in the future, it will appear below. Furthermore, as we add destinations that are good for this species they will appear below the news. .

 

Gibbon – Northern and Southern white cheeked (plus the yellow cheeked gibbon)

Northern White-cheeked gibbon

Northern southern white cheeked gibbon and yellow cheeked gibbon have all been found to be very similar

While currently classed as 3 different species, recent analysis has shown that these species are actually very similar, and likely subspecies of each other. These species may well be split out in the future, but for the time being I will have them all on this page.

The Northern white cheeked gibbon is currently only found in northern Vietnam and North Laos. They were found in China in recent times and were only declared on the edge of extirpation in 2008. They were officially declared extinct in China in 2013. While there may be no space for its return to China in the near future, should it survive elsewhere there is a likelihood for it to return to China at some point in the future. There are only a few protected areas where this gibbon survives, and probably number between 200-400 in the wild.

The Southern white cheeked gibbon had an original range that covered central Vietnam and central Laos. While it is still common in the large remaining forest blocks within this area, these patches are scattered and fragmented by human encroachment and deforestation. The Southern white cheeked gibbon has also suffered declines of around 50% over the last 45 years.

Finally the Yellow cheecked gibbon ( also known as the golden-cheeked gibbon, the yellow-cheeked crested gibbon, the golden-cheeked crested gibbon, the red-cheeked gibbon and finally  the buffed-cheeked gibbon) is also closely related to these two – at various times one or more of these species has been considered a subspecies of one of the other, as such they are clearly closely related. Whether these species will remain separate or not, I have chosen to handle them together. This is found in various areas of Vietnam Laos and Cambodia.

It has various stable populations  in reserves, but how well it does outside protected areas is less clear.

 

Gibbon – Hoolock – Eastern, Western and Skywalker

Hoolock Gibbon by Dr Raju Kasambe

The Eastern and Western Hoolock gibbon, and the Skywalker gibbon

The Hoolock gibbons are 3 species (currently classified as separate species, lets see if they stay separate).

They are currently found in eastern Bangladesh, Northeast India, Myanmar, and Southwest China. Unfortunately, while in some of these places they have large blocks of forest to live in, in other countries like Bangladesh, the population is split as the forest has been cut into smaller fragmnets, and there is little or no way for the gibbons to cross the deforested areas.

While these 3 species have split up in the last few years, there future standing and likely survival or extinction is widely varied.

 

  • The western Hoolock gibbons’s estimated population in 1980s was 3,000 individuals. By 2020 there were only about 469 gibbons left in 135 groups in Bangladesh’s northeastern and southeastern forests, according to the study. The decline is thought to be around 84% in 40 years in their Bangladesh population.
  • The Eastern Hoolock gibbons are thought to be far more numerous, however their population is predicted to shrink by 30% in the next 3 generations (45 years) so they may be uprated from vulerable in the near future.
  • The Skywalker gibbon (also known as the Gaoligong hoolock gibbon) is thought to have split from the Eastern Hoolock gibbon around half a million years ago. Unfortunately there are only thought to be 150 remaining members of this species, so they are extremely vulnerable to extinction. Unfortunately this species also has a fragmented range, which means that each small fragment has a higher chance of being pushed towards extinction. Regular translocation of these gibbons could assist in retaining a genetically healthy species – but whether this will occur is another matter.
As these are three closely related but separate species, we will include a bar that will show any articles on each one. Hopefully, in the future, there will also be 3 for places to see each of these species as well.

Gibbon – Black crested (including eastern and hainan)

Black crested gibbon

The black crested gibbon is a species found within China Laos and Northern Vietnam. Currently, there are 4 subspecies which are recognized:

  • Central Yunnan black crested gibbon (Nomascus concolor jingdongensis), Yunnan province, China
  • West Yunnan black crested gibbon (N. c. furvogaster), Yunnan province, China
  • Tonkin black crested gibbon (N. c. concolor), northern Vietnam
  • Laotian black crested gibbon (N. c. lu), Laos
Looking at fossils and other remains, it is thought that 1000 years ago, the range of this gibbon covered much of Southern China, up to the Yellow river. Perhaps more research is required, as if all these sub-species are this recent, then it may be worth treating them as one mega population and translocating gibbons between the populations so as to retain genetic health in the greater population. The total population is thought to number 1300-2000 (other estimates put the upper limit at 1500).
 
There are also two species of gibbon that were at once a considered subspecies of the black crested gibbon. While these are now considered separate species, there is still some debate about their classification, and as such, I am going to deal with these separate species within this page as well. These are the 

  • Eastern black crested gibbon
  • Hainan black crested gibbon
Apart from their isolation, and the greater population being stuck in islands of forest, there also appears to be an issue with grey langurs out-competing the gibbons. Whether this is reducing their population or not is not yet known, but having a more varied diet, when times are hard the langurs are more likely to survive

 

 

This is not a species that I have written about, but if I do in the future, it will appear below. Furthermore, as we add destinations that are good for this species they will appear below the news
