Orangutans have teeth similar to humans that can crack hard nuts. They have strong gripping hands and bones like humans. Orangutans live in forests and jungles of Southeast Asia, primarily on Borneo and Sumatra, where they feed on fruits like mangos, plums, and figs as well as insects, bark, leaves, and soil. Their long arms help them move through trees, and they have four fingers and opposable thumbs to grip tools.
