The gelada (Theropithecus gelada) is a species of primate Cercopithecidae family endemic to the Ethiopian highlands. Like baboons, are terrestrial and spend time feeding in the meadows. Some authors include in the genus Papio gelada, but since 1979 it has been included in another separate genus, Theropithecus. Theropithecus gelada is the only living species, although there are at least two separate lineages in the fossil record. Although today the gelada are restricted to Ethiopia, fossils of the genus known from South Africa, Malawi, Democratic Republic of Congo, Tanzania, Uganda, Kenya, Ethiopia, Algeria, Morocco, Spain and India. It can be distinguished from baboons by brightly colored skin on his chest. The stain is poorly defined and, in males, is dyed red and surrounded by white hair. In females, the stain is much less pronounced. However, during summer, the stain of females becomes shiny and dotted with blisters. This process is similar to the swelling of the buttocks during estrus, which is common in baboons.
