Orangutans are large, intelligent, solitary apes that live in southeast Asia (on the islands of Borneo and Sumatra). These apes mostly live in trees (they are arboreal) and swing from branch to branch using their arms.
Anatomy: Orangutans have a large, bulky body, a large head, a thick neck, very long, strong arms, short, bowed legs, and no tail. They are mostly covered with long reddish-brown hair. Orangutan hands are very much like ours; they have four long fingers plus an opposable thumb. Their feet have four long toes plus an opposable big toe. They vary from 2.6 - 4.5 ft (0.8-1.4 m) tall.
Diet: Orangutans are omnivores (they eat both plants and animals) but are mostly herbivorous (plants comprise most of their diet). They eat fruit (their favorite food), leaves, seeds, tree bark, plant bulbs, plant shoots, and flowers. They also eat insects and small animals (like birds and small mammals). They drink water that has collected in the holes between tree branches.
