Orangutan and infant in Sumatra, Indonesia

Orangutans are great apes native to the rainforests of Indonesia and Malaysia. They are now found only in parts of Borneo and Sumatra, but during the Pleistocene they ranged throughout Southeast Asia and South China. Orangutans are the largest arboreal mammals and are very well adapted to life in the trees, with arms much longer than their legs. They have grasping hands and feet with long curved fingers and toes. They have distinctive fingerprints and no visible external tails.
