The golden-bellied mangabey is notable for orange fur on the front of its body. In forests and wetlands of the central Congo Basin, groups travel through trees and on the ground to find food.
The front of the body is orange, while fur on the back half may be brown, black, white, or gray.
Groups move while searching for food both in trees and on the ground. They are most active before sunrise and eat fruits, leaves, seeds, insects, and other foods.
