Sumatran orangutan

The Sumatran orangutan is a critically endangered ape that lives only in the forests of northern Sumatra. It's one of three orangutan species, and while it's less common than its Bornean cousin, it's not as rare as the Tapanuli orangutan found in the same region.

• Lives exclusively in northern Sumatra's forests.
• One of only three orangutan species in the world.
