Tana River mangabey  (Cercocebus galeritus)

Description

The Tana River mangabey is a medium-sized, long-tailed monkey with a yellowish-brown coat, and a centre parting on the crown with very long, darker fur diverging from it on either side (2) (4). Like all Cercocebus, this species possesses white eyelids that contrast with the dark colour of the face, a feature thought to aid visual communication through facial expression (5). The molars of this species are long and the incisors are very large, allowing this mangabey to exploit hard seeds in its diet (4) (6).
