Theropithecus is a genus of primates in the family Cercopithecidae.It contains a single living species, the gelada (Theropithecus gelada), native to the Ethiopian Highlands.
The gelada (Theropithecus gelada, Amharic: ጭላዳ, romanized: č̣əlada, Oromo: Jaldeessa daabee), sometimes called the bleeding-heart monkey or the gelada baboon, is a species of Old World monkey found only in the Ethiopian Highlands, living at elevations of 1,800–4,400 m (5,900–14,400 ft) above sea level.

Old World monkey genera include baboons (genus Papio), red colobus (genus Piliocolobus), and macaques (genus Macaca). Common names for other Old World monkeys include the talapoin, guenon, colobus, douc (douc langur, genus Pygathrix), vervet, gelada, mangabey (a group of genera), langur, mandrill, drill, surili , patas, and proboscis monkey.
The Cercopithecinae are a subfamily of the Old World monkeys, which comprises roughly 71 species, including the baboons, the macaques, and the vervet monkeys.Most cercopithecine monkeys are limited to sub-Saharan Africa, although the macaques range from the far eastern parts of Asia through northern Africa, as well as on Gibraltar.
Offspring of both sexes are evicted from the group upon reaching puberty. It can be seen in many species of primates, including the gelada baboon, [1] the patas monkey, savanna baboon, [2] sun-tailed monkey, golden snub-nosed monkey, and the hamadryas baboon. [3] There are costs and benefits for individuals living in one-male groups.
In the wild, locomotor behavior of these baboons vary as a result of their need to find food and to avoid predators. [17] Gelada baboons use what is known as a "shuffle gait", where they squat bipedally and move their feet in a shuffling motion. They tend to use bipedal locomotion when traveling short distances.
For instance, the females in hamadryas baboon harems are not usually genetically related because their harems are formed by "kidnapping" females from other harems and subsequent herding. [1] In contrast, gelada harems are based on kinship ties to genetically related females. [7] Multiple harems may assemble into larger groups known as "clans ...
