Orangutans are native to Malaysia and Indonesia, and can be found on the islands of Sumatra and Borneo. In Malay, "orang" means "man," and "hutan" means "of the forest." Female orangutans are approximately 1 meter tall and 45 kilograms, while male orangutans are around 1.5 meters tall and can weigh up to 120 kilograms. Orangutans can live to be 35-50 years in age in the wild. Male orangutans live on their own, but female orangutans stay with their young until the baby orangutan is around 8 years in age. The orangutan diet consists mostly of fruit. They love eating figs! Each day, an orangutan will make a new nest to live in, high in the trees. Similar to the Bornean sun bear, orangutan are endangered because of habitat destruction, poaching and hunting, and the pet trade.
