A monkey is a long-tailed, medium-sized member of the order of Primates. The primate order also includes macaques, baboons, guenons, capuchins, marmosets, and tamarins.
Monkeys today are a member of two of the three groups of simian primates, the New World monkeys and the Old World monkeys, of which there are 264 known species. Apes and chimpanzees are not scientifically classified as monkeys, a common misconception due to their physical similarities.
Some distinguishing features between New World and Old World monkeys include the tail. Most New World monkeys have prehensile tails while Old World monkeys do not. The facial features of each group of monkeys also differ substantially; however, there are a number of shared features as well.
Monkeys are a very diverse family of species, ranging in size from the 5-6 inch Pygmy Marmoset, to the adult male Mandrill, which can be 3 feet tall. Some monkeys spend the majority if their lives in treetops, while others call savannas and grasslands home. Most monkeys survive of a diet of fruit, leaves, nuts, berries, eggs, insects and they occasionally hunt other smaller animals.
Wild marmosets that watched a video — a short flick of a marmoset opening a box to get a banana slice — are likely to copy the what they saw in the video and open the box themselves, a new study finds.

In the movie "Dawn of the Planet of the Apes," a brilliant, mutant chimp named Caesar yells "Go!" at a group of humans. His deep, guttural voice startles the people, but even more surprising are his vocalizations.
Losing yourself in an acting role might be difficult, but imagine how hard it is if the human you're playing isn't human at all. Karin Konoval, who plays the orangutan Maurice in "Dawn of the Planet of the Apes" talks about the transformation.
A new study that tested the musical taste of chimps found that the animals shun the steadily strong beats common in Western genres, but they're drawn to Indian ragas and traditional tunes from West Africa.
