One of the largest baboons, the olive baboon (Papio anubis) is named for its coat, which, at a distance, is a shade of green-grey. Close-up, its coat is multicoloured, due to rings of yellow-brown and black on the hairs. Also called the Anubis baboon, it inhabits savannahs, steppes and forests and lives in troops of males and females that consist of between 20 and 50 members, but sometimes these troops can consist of over 100 baboons. The species inhabits a strip of 25 equatorial African countries, very nearly ranging from the east to west coasts.
