For the TV show Monkey see Monkey (television)

A monkey is a primate that isn't a prosimian (or a tarsier) or an ape. Put more technically, it is any haplorhine primate not belonging to the families Tarsiidae, Hylobatidae, and Hominidae. This rather unsatisfactory definition results from the fact that the animals called monkeys do not correspond to any single taxon in modern scientific classification. The name is used both for the Old World monkeys (family Cercopithecidae) and New World monkeys (families Cebidae, Nyctipithecidae, Pitheciidae and Atelidae). However the Old World monkeys are part of a larger group, the catarrhines, which also includes the apes. Because of their size and similarity to monkeys, chimpanzees are sometimes incorrectly called monkeys even though they are apes.

Because they are not a single coherent group, monkeys do not have any important characteristics that they all share and are not shared with other groups. They range in size from the Pygmy Marmoset, at 10 cm (4 inch) long (plus tail) and 120 g (4 oz) in weight to the male Mandrill, almost 1 metre (3 ft) long and weighing 35 kg (75 lb). Some are arboreal (living in trees), some live on the savannah; some eat fruit, some eat leaves, and some eat insects; although most have tails (sometimes prehensile), others do not; some have trichromatic colour vision like that of humans, others are dichromats or monochromats. Although all, like the apes, have forward facing eyes, the faces of Old World and New World monkeys look very different. To understand the monkeys, therefore, it is necessary to study the characteristics of the different groups individually.
