Monkeys live in a wide range of climates, but they are most often found in the warm and wet tropical forests of Africa and South America. They generally move around by clinging and leaping through the trees (quadrupedalism). Some monkeys have prehensile tails, which they use to grip branches. Others, like the baboons and apes, walk on all fours like dogs.
The monkeys’ remarkable dexterity enables them to grasp and manipulate objects, find food, and even use tools. They communicate in a variety of ways, using facial expressions, vocalizations, and body movements. Staring at another monkey signals that it is a threat and could trigger a fight, so it is best to look down or away instead. Monkeys also use loud vocalizations to mark their territory.
Many species of monkey live in social groups that consist of females and males. Some, such as the titi monkeys and marmosets of South America, operate in monogamous, pair-bonded groups. But other monkeys such as macaques, capuchins, and baboons typically live in multimale, multifemale troops. When a male monkey reaches maturity, at around five years of age, it must leave its troop and find a new one to join.
In the wild, most monkeys have a life span of about 45 years. But in captivity, monkeys can live for much longer than that. Monkeys can thrive in captivity if they have a good quality of life with lots of interaction and challenges to keep them busy, but they need to be able to interact with other monkeys to prevent loneliness.
