Facts About Monkeys

Monkeys are among the most intelligent animals and are adept at problem-solving. They live in groups called troops that consist of related females and their offspring, as well as one or more males. In addition to facial expressions and body language, monkeys communicate with vocalizations that include barks, screams, grunts, squeaks, hoots, wails, and deep howls. When they are startled, they sometimes shake their heads. In captivity, monkeys can be aggressive toward other monkeys and even their owners. For this reason, they are usually not kept as pets. Instead, they are often given to zoos and other sanctuaries after reaching adulthood.

Many different species of monkeys exist in the wild, and their range covers much of the world. They prefer tropical rainforests to desert savannas, and some are even found in mountain areas. Some, such as geladas and golden monkeys, live in snowy regions. Others, such as owl monkeys and Japanese macaques, are primarily tree dwellers but spend some time on land as well.

Some Old World monkeys, such as colobus and mandrill monkeys, have remarkable anatomical features that make them stand out in a troop, including a stub for a thumb (a condition known as abrachia) and bright coloration. Other notable characteristics are the prehensile tail of New World monkeys and their long fingers, which help them grasp branches as they swing from tree to tree. They also play an important role in their native habitat by pollinating plants and dispersing seeds.
