The hamadryas baboon is found in North Africa and the Arabian Peninsula where it lives in the deserts and dry plains. These baboons eat a wide variety of fruits, grass, insects and roots which they manage to find even in the drier regions. They spend most of their time on the ground where they are very social and have a very complex social structure. The baboons live in groups headed by one male, the leader. He controls a group of females, their off-spring, and occasionally a "follower" male thought to be related to the leader. Then these groups may come together to form a clan and a few clans can come together to create a band, and finally a few bands can create a troop making a lot of baboons together in one area.
