Monkey
The two groups of monkeys live in different places: the New World Monkeys in South America and the Old World Monkeys live mainly in  Africa and Asia. New World Monkeys are often smaller than Old World Monkeys. Monkeys have long arms and legs to help them swing from trees. The monkeys often climb with the help of their tails. Some monkeys' tails can wrap tightly around branches, almost like a "fifth limb". This type of tail is 'prehensile'.
