Monkeys are smart, curious creatures with forward-facing eyes and flat noses. They have opposable thumbs and can use tools to help them in their environment. Some species are considered endangered and may need special care in captivity or in the wild.
They can be playful and loving, and many species are very sociable in captivity. Some can also learn tricks and even speak human languages. Monkeys are also known to explore a lot of the same emotions as humans: love, anger, sadness and mourning.
Like other mammals, monkeys are omnivores. Typically, their diet includes fruits (such as bananas), vegetables, seeds, leaves and flowers, nuts, and meat when they can catch it. In the wild, some monkeys eat more plants than others—such as gelada monkeys that munch on grass and baboons that eat young antelope and rabbits.
Often, monkeys can be quite dangerous. For example, the ferocious mandrill (Mandrillus sphinx) from West Central Africa is the largest monkey in the world and can weigh up to 72 pounds, according to the Wisconsin National Primate Research Center. It has sharp 2-inch teeth that can rip through skin, and its strong jawline can snap bones with ease.
It’s not legal to have monkeys as pets in all states, and laws vary depending on the type of monkey and its habitat. If you do want to keep a monkey as a pet, it’s best to find a dealer with a good reputation and an USDA permit number.
