Which monkeys are endangered

In an unprecedented effort, over a hundred field primatologists have pooled their knowledge to create the world's most comprehensive survey of threatened primates — and the results are a dire mosaic of crisis and hope Their assessment was one part of a global analysis of mammal species.

The results of the primate component were released to coincide with the 22nd Congress of the International Primatological Society, in order to highlight the severe dangers now facing the world's primate fauna.

Virtually all gibbons are threatened with extinction — and one of the rarest subspecies, the Yunnan white-handed gibbon, may already be extinct. All great apes — all gorillas, all chimpanzees, all orangutans, all bonobos — are either Endangered or Critically Endangered. As to where the Indonesian government stands on primate conservation, the timbre of a recent news story is not encouraging.

The country is set on a massive hydroelectric dam project and appears to be actively downplaying concerns about the effect its construction could have on Tapanuli orangutans, a species discovered just last fall and already feared to be endangered.

Realizing so many of our cousins face so many existential threats of our own making can be disheartening, but there is one silver lining: No primate has gone extinct in more than years.

There have been some close calls, though. The question now is, can we make it another years with our family tree intact?

How protecting the okapi could bring income, sanitation, health services, and security to a remote area of the Democratic Republic of the Congo.

Not everyone is happy about that. A scientist looks to a Chesapeake Bay retriever for answers. As the IUCN meets this week in Hawaii, a new report highlights the biggest threats to the planet's most endangered species.

We will keep you informed with the latest alerts and progress reports. Big, Beautiful Brazil That more primates—crested capuchins, dwarf marmosets, red-bellied titis, sakis, uakaris, night monkeys, and so on—live in Brazil than anywhere else should come as no surprise.

To protect primates and their habitats, we work on many fronts such as law enforcement, education, and creating effective protected areas. ESI is a proof that we can save primate species and their habitats. Join us to continue achieving remarkable conservation results! Your support is needed now more than ever.

Our closest living relatives are being wiped out by large-scale habitat destruction — especially from the burning and clearing of tropical forests, hunting for food, and the illegal wildlife trade. IUCN estimates the current population to be at 2, individuals. This lemur is the only primate to live only in wetlands, as it resides in Madagascar's shrinking Lake Alaotra marsh.

Conservation work has ended the hunting of the lemur for food, but Lake Alaotra marshlands' agricultural use still hurts the population. The Bemanasy mouse lemur Microcebus manitatra , which was identified as a separate species in , lives in a southeastern Madagascar forest fragment. It is under threat from logging and slash-and-burn agriculture. Very few individuals are thought to live in these forest fragments. At just over 10 and a half inches, they are one of the larger mouse lemurs.

Their coat is greyish brown on their back and tail. The underside of the coat is beige with some dark fur undercoat. There are currently two populations in forest reserves. Deforestation and hunting led to their critically endangered status and an estimated population of around 1, total individuals.

Hunters use traps and cut down the trees the lemur inhabits and remove them from their holes. The indri Indri indri , also called the babakoto , is found in Madagascar's eastern rainforests and is the only lemur that sings.

In addition to their singing abilities, they have a teddy bear appearance with short, dense fur, round ears, and small eyes. Long protected by taboos against hunting the species, the indri now faces extinction resulting from hunting and deforestation. According to the IUCN report, the estimated population size lies somewhere between 1, and 10, individuals. The aye-aye Daubentonia madagascariensis has the broadest range of any lemur, as their ability to consume a varied diet allows aye-ayes geographic flexibility.

The aye-aye uses its long middle finger to tap on trees to find grubs, which is called percussive foraging. Aye-ayes are the only primate to use this form of echolocation to find food. Poaching is the primary population threat to the endangered aye-ayes. Reliable population estimates are unavailable due to their solitary nature and enormous individual territories.

The Rondo dwarf galago or Rondo bushbaby Paragalago rondoensis found in Tanzania is notable for being the smallest known galago and sports a bottlebrush tail. They have a distinctive " double-unit rolling call. The most recent population count of the species was four individuals in Fewer than 2, individuals remain, and some parts of their former range have no remaining roloway monkeys. According to the report, the bushmeat trade decimates their numbers each year, as 80 percent of Ghana's rural people rely on bushmeat as their primary source of protein.

The kipunji Rungwecebus kipunji , first discovered in , lives solely in the mountain habitats around Mount Rungwe in Tanzania. They have a particularly notable and very loud, low-pitched honk-bark.

Kipunji serves as the flagship species for conservation work in the area. There have been significant strides in restoring the habitat, although they are still in grave danger of extinction — 1, individuals in 38 groups remain. The white-thighed colobus Colobus vellerosus has a fragmented distribution in eastern Africa from the area between the Sassandra and Bandama Rivers in Ivory Coast to Benin and possibly extending into southwestern Nigeria.

Adults are primarily black with white with markings on their thighs and face and have an entirely white tail. An infant colobus is born with all-white fur, which darkens beginning around three months of age. Critically endangered, this animal's numbers are rapidly declining due to uncontrolled hunting. The current population is estimated to be below 1,
