The Mandrill (Mandrillus sphinx) is a primate of the Cercopithecidae (Old-world Monkeys) family, closely related to the baboons and even more closely to the Drill. The Mandrill is the world's largest monkey species.
Mandrills are recognized by their olive-colored fur and colorful face and rump amongst males (color will grow stronger with sexual maturity); females have duller colors. Males can weigh up to 60 lbs (30 kg), females about half as much. They grow to be about half a meter long (20 inches) and can survive up to 25 years in captivity.
Mandrills are found in the tropical rain forests of Equatorial West Africa (South Cameroon, Gabon, and Congo).
Mandrills are social creatures and may be found in groups ranging from 5 to 50 individuals, led by an older dominant male.
Mandrills are omnivores and acquire their food by foraging (mainly plants, insects and smaller animals) from the ground as they are terrestrial, although they may climb trees occasionally to sleep. Their main natural predators are leopards and cheetahs. Because of over-hunting by humans, the Mandrill has become endangered. The situation is exacerbated by deforestation causing Mandrill habitats to disappear.
The gestation (pregnancy) time for Mandrills is 6-7 months and young are usually born in Jan-April. However, Mandrills mate throughout the year during the estrus cycle, which occurs once every 33 days.
Although the Mandrill does not hunt larger prey, it is well adapted to fighting and is not to be provoked.
