Cercocebus

The genus Cercocebus encompasses nine species of mangabeys, which are slender, long-limbed monkeys found in African tropical forests. These monkeys are characterized by cheek pouches and deep depressions under their cheekbones. They are social animals that communicate vocally, often with loud calls from males.1

Mangabeys primarily feed on seeds, fruit, and leaves, using their large front teeth to access tough-coated fruits. Species within Cercocebus typically have short fur, light-colored eyelids, and often carry their tails curled over their backs. Some species, like the Tana River mangabey, are critically endangered due to habitat loss.1

Mangabeys are classified into two genera, Cercocebus and Lophocebus. The Cercocebus genus is closely related to mandrills and drills, while Lophocebus is more closely related to baboons.1
