Characteristics

All baboons have long, dog-like muzzles, heavy, powerful jaws with sharp canine teeth, close-set eyes, thick fur except on their muzzles, short tails, and rough spots on their protruding buttocks, called ischial callosities. These calluses are nerveless, hairless pads of skin that provide for the sitting comfort of the baboon.

All baboon species exhibit pronounced sexual dimorphism, usually in size, but also sometimes in colour. Males have much larger upper canines compared to females and use them in threat displays. Males of the hamadryas baboon species also have large white manes.
