The gelada (Theropithecus gelada), sometimes called the gelada baboon, is a species of Old World monkey found only in the Ethiopian Highlands, with large populations in the Semien Mountains. Theropithecus is derived from the Greek root words for "beast-ape." Like its close relatives the baboons (genus Papio), it is largely terrestrial, spending much of its time foraging in grasslands.The gelada is large and robust. It is covered with buff to dark brown, coarse hair and has a dark face with pale eyelids. Its arms and feet are nearly black. Its short tail ends in a tuft of hair. Adult males have a long, heavy cape of hair on their backs.
