The Hamlyn’s monkey[1] (Cercopithecus hamlyni), also called the owl-faced monkey, is an Old World monkey inhabiting the Congo’s bamboo and primary rain forests.
- The fur of an adult Cercopithecus hamlyni is black and olive-gray. The fur is darker on the lower abdomen, hind legs, and arms.
- An olive-gray tint appears on the backs of adults. Their almost monotonous fur makes them almost invisible to predators.
- The fur of these animals is long, thick, and delicate. However, the face of an adult Hamlyn’s monkey is its most distinctive feature.
- These primates have a horizontal stripe across the forehead and a vertical stripe from the center of the forehead to the lip area.
- These two bands vary in color from creamy yellow to white, forming a T-shaped facial marking.
