Sumatran Orangutan

The Sumatran orangutan is a great ape found only on the Indonesian island of Sumatra, one of three recognized orangutan species alongside the Bornean and Tapanuli orangutans. It is generally more slender than its Bornean relative, with a longer face and a coat of reddish fur, and it spends more of its time in the trees, rarely descending to the ground. Sumatran orangutans are largely solitary, feed mainly on fruit supplemented by leaves, bark and insects, and are known for sophisticated tool use, including using sticks to extract insects or seeds. Confined to rapidly shrinking forest habitat due to logging and conversion of land for agriculture, the species is classified as critically endangered.
