Black Spider Monkey

Ateles chamek

Endangered

At very high risk of extinction in the wild in the near future.

Spotted something wrong?

The Peruvian spider monkey is a large, entirely black primate of the western Amazon, with extremely long arms and a prehensile tail that it uses as a fifth limb. It lives in fission-fusion societies: the large group splits each day into subgroups that search for ripe fruit separately. Its reproduction is extremely slow, with one infant every three or four years, which makes it exceedingly vulnerable to hunting. It is one of the first primates to disappear from a hunted forest.

Fun facts

  • It is one of the best indicators of the health of an Amazonian forest: because of its size, its slow reproduction and its dependence on the fruit of large trees, it is the first species to disappear when hunting or selective logging arrives.
  • It has no thumb, like all spider monkeys: its hands work as hooks and all fine manipulation is done with the tail, whose bare tip has dermal ridges like a fingerprint.

Where to find it

Best time: All year in the Amazon of Peru, Bolivia and Brazil, by day; it moves through the high canopy and gives itself away by the branches it sets swaying.

How to help

The black spider monkey is classified as endangered. Organisations such as the IUCN, WWF and the Wildlife Conservation Society work specifically on its conservation and that of its habitat; looking into their programmes is a good starting point if you want to get involved.

It's documented in 8 protected areas — one reason why protecting these places matters for its conservation.
