Habitat Mandrills live in dense rainforest and coastal forests, although they will sometimes venture into savannah. They feed on fruits, leaves, roots, seeds, nuts, fruit, greens and invertebrates. There are two distinct group types in mandrill society. One type consists of one very large male and an average of 15 females. The other group-type is multi male and multi female, and can include up to 200 members.
Mandrills are predominantly terrestrial.
They sleep in trees at a different site each night. Reproduction After a gestation period of 220 days, females give birth to one infant. Records Mandrills are the most colourful mammals in the world. The skin colours brighten as the animal gets more excited.
