Tapanuli Orangutan

Pongo tapanuliensis

Critically Endangered

At extremely high risk of imminent extinction in the wild.

Spotted something wrong?

The Tapanuli orangutan was described as a species in its own right in 2017, becoming the seventh known great ape and, immediately, the most threatened on the planet. The entire population, of fewer than 800 animals, survives in some 1,100 square kilometres of forest in the Batang Toru ecosystem, in northern Sumatra. It is told apart from the Sumatran orangutan by a smaller skull, curlier, cinnamon-coloured hair, and a long call of higher pitch and longer duration. Adult males develop large flat cheek pads.
