Sumatran Orangutan

Pongo abelii

Critically Endangered

At extremely high risk of imminent extinction in the wild.

Spotted something wrong?

The Sumatran orangutan is slimmer and more social than its Bornean relative, with a narrower face and a long, pale beard in the males. It is the most arboreal of the great apes: it comes down to the ground far less often than the Bornean orangutan, partly because it shares its range with the tiger. It spends the day searching for ripe fruit and builds a fresh nest in the crowns every night. Its population is concentrated today in the Leuser Ecosystem, at the northern tip of the island.
