There are 12 [[genera]] and about 71 [[species]]. the [[baboon]]s, the [[macaque]]s and the [[vervet monkey]]s. Most of then live in [[sub-Saharan Africa]], but the [[macaques]] range from the far eastern parts of [[Asia]] through northern [[Africa]], and [[Gibraltar]]. == Characteristics == The various species are [[adapted]] to the different terrains they inhabit. Tree-dwelling ([[arboreal]]) species are slim, delicate and have a long tail. [[terrestrial animal|Ground-dwelling]] species are heavier, and their tail may be small or nonexistent. All species have well-developed [[thumb]]s. Like many Old World monkeys, they have pads on their bottoms. These are called ''ischial callosities''.<ref>{{cite web|url=https://monkeybuiznezz.wordpress.com/tag/ischial-callosities/|title=Ischial callosities|publisher=MonkeyBuiznezz|access-date=2014-02-12}}</ref> They let the monkeys sleep sitting upright on thin branches, beyond reach of predators, without falling off. In some species, these pads change their colour during the mating period.<ref>Steudel K. 1981. Functional aspects of primate pelvic structure: a multivariate approach.
