Monkeys are haplorhine (dry-nosed) primates, a paraphyletic group generally possessing tails and consisting of approximately 260 known living species. Many monkey species are tree-dwelling (arboreal), although there are species that live primarily on the ground, such as baboons.he New World monkeys and the Old World monkeys are each monophyletic groups, but their combination is not, since it excludes hominoids (apes and humans). Thus the term monkey no longer refers to a recognized scientific taxon.
