monkey wiki:
>For other uses, see Monkey (disambiguation). A monkey is any member of two of the three groupings of simian primates. These two groupings are the New World and Old World monkeys of which together there are nearly 200 species. Because of their similarity to monkeys, apes such as chimpanzees and gibbons are sometimes incorrectly called monkeys. Also, a few monkey species have the word "ape" in their common name. Because they are not a single coherent group, monkeys do not have any important characteristics that they all share and are not shared with the remaining group of simians, the apes.
