Diana monkey

The Diana monkey (Cercopithecus diana) is an Old World monkey, a black-grey guenon that lives in the high canopy forests of West Africa, from Sierra Leone through Liberia to western Cote d'Ivoire. It is named for its white brow, said to resemble the bow of the Roman goddess Diana, and it also has a white throat, ruff and beard, white underarms and a white stripe down each thigh. Adults weigh 4 to 7 kilograms and healthy animals may live up to 20 years. The species is found in primary forest and does not thrive in secondary forest. It is noisy: females give distinct alarm calls for different predators, and other forest animals such as hornbills understand them. The IUCN and the United States Fish and Wildlife Service regard it as endangered, mainly because of habitat destruction and hunting for bushmeat.
