These New World monkeys live exclusively in the rainforest. This monkey gets its name from its loud vocalizations, which sound like a bark or a roar. In fact, these vocalizations are so loud that they can be heard from up to 3 miles away!

There are 15 different species of howler monkey, including the endangered Yucatán Black howler monkey. Thanks to their distinct cries, they’re a part of many legends and myths.

3. Capuchins

Capuchin monkeys are known for their dexterity and intelligence. These small monkeys respond well to training, which has led to roles in movies like Night at the Museum and 3:10 to Yuma. In the wild, the capuchin is known for using tools like rocks to crack open nuts.

While capuchins are mostly found in rainforests, they can also be found in mangroves and dry forests. When under threat, capuchins whistle to other members of their group to alert them of danger. There are many predators that attack capuchins, including boa constrictors.

4. Spider Monkeys

These monkeys have long limbs and advanced prehensile tails, which they use to swing from branch to branch. Not only are spider monkeys known for hugging each other, but they’ll also wrap their tails around each other. Unlike most monkeys, spider monkeys don’t have thumbs, which leads them to rely on their tails for many tasks.

5. Macaques

Native to Africa and Asia, macaques include 23 different monkey species. One species, the Japanese macaques, is known for bathing in hot springs. Another species, called the barbary macaque, is the only monkey that lives in Europe!

Macaques are highly social and use vocalizations, facial expressions, and posture to communicate with each other. When macaques are around humans, they’re also known for being pickpockets!

The unusual-looking monkey is famous for its long, large nose. While researchers aren’t sure why its nose is so large, it’s believed that the nose might amplify its vocalizations.

These monkeys are found across the Thai-Malay Peninsula, on islands like Borneo, Java, and Sumatra. Due to habitat threats, some surilis, like the Java surili, are endangered.

Doucs have bright and colorful markings which can vary from species to species. The red-shanked douc has bright burgundy legs, while the grey-shanked douc has orange marking across its face.

30. Kipunji

The kipunji was discovered by researchers in 2003, making it the first monkey genus discovered since 1923. This monkey prominently features in folklore and myths, and before its official discovery, it was assumed to be a creature of legend. It has a loud and unusual cry that sounds like a combination of a honk and a bark. Even though this monkey was discovered recently, it’s on the endangered species list.

What is a monkey?

Monkeys are a type of mammal known as simians. Most monkeys are arboreal, which means they live in trees. However, there are some species of monkeys that are terrestrial and never venture into trees at all.

While there are some similarities between monkeys and apes, monkeys have tails, and apes don’t. Some monkeys have prehensile tails that they can use to grasp branches or even pick up objects. Apes also tend to be larger and stronger than most monkey species.

The monkey is divided into two groups: Old World monkeys and New World monkeys. Old and New World monkeys live in different parts of the world and have different physical characteristics. For example, Old World monkeys have narrow noses with nostrils that face downward, as apes and humans do, but New World monkeys have broad noses with nostrils that face outward.

There are a total of 160 known Old World monkey species as well as 174 species of New World monkeys, adding up to a total of 334 monkey species! Even though there are hundreds of monkey species, these monkeys are divided into groups and families. Monkeys are amazing animal that has all kinds of unique traits!
