A monkey is a type of primate known for its playful behavior and social nature. They are typically found in tropical forests and savannas, living in groups called troops. Monkeys have long limbs, prehensile tails, and expressive faces, which help them navigate trees and communicate with each other. There are two main types of monkeys: New World monkeys and Old World monkeys. New World monkeys, like the capuchin, are found in the Americas and often have flat noses. Old World monkeys, such as the baboon, are native to Africa and Asia and usually have narrow noses. Both types are important for their ecosystems.
