Sclater's guenon

Sclater's guenon (Cercopithecus sclateri), also known as Sclater's monkey or the Nigerian monkey, is an arboreal and diurnal Old World monkey restricted to the forests of southern Nigeria between the Niger and Cross Rivers, a region within the Guinean Forests of West Africa biodiversity hotspot. Reginald Innes Pocock described it in 1904 and named it for Philip Sclater; it was once treated as a subspecies of the red-eared guenon. It should not be confused with the white-throated guenon of Nigeria and Benin. The species was thought nearly extinct until the late 1980s, when several isolated populations were found. None lies in an official protected area, but three are protected by local people who regard the monkeys as sacred. Its diet is unrecorded, though it is likely mostly fruit eating. Hunting and loss of forest have isolated and reduced its populations.
