Orangutans are great apes that live in the tropical forests of Sumatra and Borneo in Southeast Asia. They grow to be 4 to 4.5 feet tall and weigh between 90 to 180 pounds depending on their gender. Orangutans eat a variety of foods including fruits, leaves, bark, termites, and ants. Females give birth once every 8 years and carry their babies for 9 months. Orangutans are threatened by habitat loss and poaching.
