monkeys (animals) en

Common term referring to the New World monkeys and the Old World monkeys, two of the three groupings of simian primates, the third of which is the apes. There are over 250 known living species of monkey. Because of their similarity to monkeys, apes are often called "monkeys" in informal usage. Furthermore, some monkey species have the word "ape" in their common name, causing further confusion. Because monkeys are not a single coherent group, they do not all share any particular traits that are not also shared with the apes.
