Cercocebus

Cercocebus is a genus of Old World monkeys known commonly as the mangabeys. These primates are found primarily in central and West Africa. The members of this genus are characterized by their robust build, elongated faces, and large cheek pouches, which they use to store food while foraging. Cercocebus species are primarily terrestrial, although they do spend time in trees.

Taxonomy

The genus Cercocebus was first described by É. Geoffroy in 1851. It belongs to the family Cercopithecidae, subfamily Cercopithecinae. The classification of mangabeys has undergone revisions and previously included species now placed in the genus Lophocebus.

Species

The genus Cercocebus includes several species:

• Cercocebus agilis – Agile mangabey
• Cercocebus atys – Sooty mangabey
• Cercocebus chrysogaster – Golden-bellied mangabey
• Cercocebus galeritus – Tana River mangabey
• Cercocebus torquatus – White-collared mangabey

Distribution and Habitat

Cercocebus species are found in a variety of forest habitats, including wet lowland forests, swamp forests, and bamboo forests. They are distributed from Senegal and Ethiopia in the west to Uganda and Kenya in the east.

Behavior

Mangabeys are both arboreal and terrestrial and are known for their leaping abilities. They live in social groups that can include up to several dozen animals. Their diet primarily consists of fruits, seeds, and invertebrates.

Conservation

Several species of Cercocebus are threatened by habitat destruction and hunting. The Cercocebus galeritus, for example, is listed as Endangered on the IUCN Red List due to its restricted range and ongoing habitat loss.
