Olive baboons (Papio anubis) live in groups of 15 to 150, with many females, a few males and the offspring. Social hierarchy is important to baboons. Males fight to establish dominance, whereas females inherit dominance from their mothers. The olive baboon is so named for its coat, which is a grey-green color from a distance. Males are larger than females, weighing on average 53 pounds, whereas the female weighs on average 33 pounds.
