Mandrill

Mandrillus sphinx

Quick answer

The mandrill is the largest monkey species, with males displaying vivid blue and red facial ridges and rumps. Weighing up to 35 kg, living about 25 years, and reaching 40 km/h, it inhabits rainforests of central Africa and carries the longest canines relative to body size among primates.

Distribution and habitat

Mandrills live in Rainforests of Gabon, Cameroon, Congo, Equatorial Guinea, and southwestern Central African Republic. Preferred habitat includes rainforests and gallery forest of central africa. Across Africa, population density reflects prey availability, water access, and human disturbance. Protected areas and wildlife corridors remain essential for long-term persistence.

Physical traits and behaviour

Mandrills typically reach about 1 m in length and 35 kg in weight, with top speeds near 40 km/h. The world's most colourful primate. Daily activity, social structure, and seasonal movements reflect pressures in their native environment.

Diet and ecological role

Mandrills feed on omnivore — fruit, seeds, leaves, insects, and small animals. Foraging shifts with season and local abundance. As mammals, they influence food webs — controlling prey, dispersing seeds, or shaping habitat through feeding and movement.

Conservation and coexistence

Listed as Vulnerable on the IUCN Red List. Habitat loss, hunting, and climate change threaten many populations. Responsible ecotourism and community conservation help in parts of their range. Never approach or feed wild mandrills.

Human interest and research

Mandrills feature in folklore, tourism, and scientific study worldwide. Ongoing research tracks population trends, genetics, and responses to environmental change — data that guides national protection policies.
