What are some interesting characteristics of monkeys?

Some of the most interesting characteristics of monkeys are those that are similar to humans and other primates, such as grasping hands, forward-facing eyes and the ability to express a wide range of emotions. Most species of monkeys live in forested areas and are well adapted to living in trees.

The term "monkey" describes a family of primates with at least 264 known species. They are different from apes in that they have tails and are usually much smaller. Monkeys also have better senses of smell and smaller brains than their ape cousins. Monkeys can be found all over the world except in Europe and North America outside of southern Mexico.
