Hamlyn's monkey

Hamlyn's monkey (Cercopithecus hamlyni), also known as the owl-faced monkey, is a species of Old World monkey that inhabits the bamboo and primary rainforests of the Congo. Its original describer believed it to be an intermediate between the guenons of the genus Cercopithecus and the mangabeys of the genus Cercocebus. It is thought to be a frugivore-folivore, eating both fruit and leaves. In captivity it has been known to live for about 33 years. Two subspecies are recognised, the nominate Cercopithecus hamlyni hamlyni and Cercopithecus hamlyni kahuziensis.
