Baboons are African Old World monkeys belonging to the genus Papio, part of the subfamily Cercopithecinae. There are five species, which are some of the largest non-hominid members of the primate order; only the Mandrill and the Drill are larger. Previously, the closely related Gelada (genus Theropithecus) and two species of Mandrill and Drill (genus Mandrillus) were grouped in the same genus, and these Old World monkeys are still often referred to as baboons in everyday speech. They range in size and weight depending on species. The Guinea Baboon is 50 cm (20 inches) and weighs only 14 kg (30 lb) while the largest Chacma Baboon can be 120 cm (47 inches) and weigh 40 kg (90 lb). A group of baboons is collectively called a troop.
