DESCRIPTION OF THE SPECIES
A large primate (The male’s body length is about 74cm, the female’s is about 60cm. The tail length is approximately 45cm. The males weigh 39-32kg, the females weigh 14-20kg). They have a typical for baboons appearance. The colouration of fur varies from olive to brown. Olive baboons are very strong animals with strong jaw allowing them to crack bones, nuts and so on. The baboons differ with the spots of bare ‘sexual skin’ in anogenital part. The colour and the condition of this skin depends on the level of sex hormones in the blood. So, the bright red colour of this sexual skin of pubescent animals becomes even brighter during the mating season. They live in big groups of 8-200 animals; but usually the group consists of 30-60 animals. There are always several pubescent animals in the group, but the leader is only one – a strong adult male.
They eat fruits, seeds, tubers, roots, leaves, and flowers. They also hunt game: invertebrates, reptiles, birds and small mammals.
The average lifespan in the wild is 12-15 years, and 20-25 years in zoos.
