Sumatran Orangutan

Animal Facts

They share more than 97% of our own human DNA. Orangutans are mostly solitary in the wild and due to habitat loss, researchers are seeing them congregating in closer proximity due to fragmentation of forests. There are now three species of orangutan, including the Sumatran orangutan (Pongo abelii), the Bornean orangutan (Pongo pygmaeus), and the Tapanuli orangutan (Pongo tapanuliensis).

The Sumatran orangutan displays extreme sexual dimorphism.  Males can weigh 200 pounds while females may weigh around 100 pounds. Male orangutans grow large-face cheek pads around the age if 15 years old. 

Orangutans have been know to live for 30 years in the wild and up to 50 years in captivity.
