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. Most species are also active during the day (diurnal). Monkeys are generally considered to be intelligent,
particularly Old World monkeys.
