The Guinea baboon[1] (Papio papio) is a baboon of the Old World monkey family.
- Some (older) classifications only list two species of the Papio genus, this one and the Hamadryas baboon.
- The fur of Papio papio is reddish-brown in color with a considerable geographic variation.
- Those individuals from the western part of the range are lighter and conspicuously red than those from the eastern part, where the individuals are darker and more tan.
- Unlike many other baboon species, the Guinea baboon characteristically displays the same coat color on the cheeks, back, arms, and abdomen.
- Individual hairs have multiple color bands and a wavy texture. The skin on the face of this species is purplish-black.
- The moderate amount of visible hairless skin around the anal area in males is pink in color.
- Female anogenital skin changes color based on reproductive status and age.
