Part of the super family Hominoidea, there are two sub species of Orangutan native to the Borneo and Sumatran rainforests in Malaysia and Indonesia respectively. Orangutans are the most solitary of the great apes, and are known to use a variety of tools.

Orangutans subsist of a diet composed primarily of fruit, vegetation, honey and insects, and have been known to eat bird eggs. Both species are currently critically endangered due to habitat destruction and poaching.

There is great sexual dimorphism in Orangutans; the male has an arm span of over two metres. Orangutans are the only truly arboreal great ape, and are not true knuckle walkers, walking on their fists instead.
