The blue-faced baboon's correct name is the mandrill. Mandrills are large African monkeys closely related to baboons that inhabit jungles and forests. They have distinctive blue-ridged faces with a red stripe down the middle and additional colorful areas on their bodies.
The mandrills' coloring plays a significant part in group communication; for instance, their chests turn blue and the blue of their buttocks brightens when they are excited. Mandrills are very social and live in groups of up to 50 individuals, each group containing a single dominant male and several females along with their young. The dominant male has exclusive mating access to the females in his group. He is much larger than the females and has a key role in defending the group.
