Monkey. A monkey is any nonhuman primate, with the usual exception of the lemurs and tarsiers.[1] Thus defined, there are three type of monkeys: (1) non-human hominoids (also known as apes), (2) old world monkeys, and (3) new world monkeys.
However, only the latter two are currently considered "monkeys" by most biologists. There are about 280 known living species of monkey (260 if non-human hominoids are excluded). San Diego Zoo's Animal Bytes: Monkey. Monkeys from the start Monkeys have been a part of San Diego Zoo Global since we were founded in 1916, and by 1925 we had 22 species represented.
Since then, we have celebrated the births of many endangered monkey species, including golden lion tamarins, lion-tailed macaques, red-shanked douc langurs, gray langurs, and mandrills. Today, the Zoo is home to 27 monkey species, including colobus, swamp monkey, mangabey, mandrill, and guenon species in Lost Forest, langurs and macaques in Asian Passage, and spider monkeys in Discovery Outpost.
