30 fantastic types of monkeys (lists, facts, and photos!)

There are many fascinating types of monkeys found all over the world and these monkeys can be divided into different categories based on their attributes, origin, and native environment. They all vary in size, coloration, and where they live in the world – many of which I will show you in this post!

At the level of species, there are around 250 types of monkeys all around the world! These can be divided into two main types: The New World Monkeys and the Old World Monkeys, depending on where they originate from.

I will explain more about these major type classifications at the end of this article and include a list of all monkeys recorded to date.

Monkeys differ in many aspects, their size, lifespan, diet, habitat, and even their type of teeth!

I have selected 30 of the most fascinating types of monkeys, representing all monkey types from different climates, habitats, and countries.

After going through these (and you can use the table of content to jump to whichever you like) I will go deeper into how these monkeys group into more general groups, and what sets them apart!

Bald Uakari

The bald Uakari is a type of monkey that is found in the Amazon rainforest where it prefers to live near rivers in flooded forests. Because of this they only live high up in the trees during the rainy season. They are characterized by their bright red hair and bald head, which helps them to stay cool in the hot jungle. The males with the reddest faces attract most females.

The females have a special gland that releases a smell that encourages the males to mate with them. They live in large groups of up to 100 individuals and travel large distances of around 3 miles (5 km) every day to find enough food.

They fiercely defend their territory by making loud noises and moving their tail. Their diet consists mainly of fruit and seeds. Its jaw and teeth are specially adapted so that it can break the hardest seeds that other animals cannot eat.

Barbary Macaque

The Barbary macaque is found in the Atlas Mountains, which are located between Morocco and Algeria. Some of them live in Gibraltar, making them the only wild monkeys in Europe. They have a very unique appearance that includes short, red-orange hair and no tail.

They are known to be very aggressive, which has caused them to be hunted by humans. They are also one of the few types of monkeys that live in a cold climate.

The males play an unusually large role in rearing all the young monkeys because they do not know which of them are theirs. The leader of the group is a female. They are popular in the illegal pet trade.

Black Snub-Nosed Monkey

Snub-nosed monkeys of the genus Rhinopithecus are found along the eastern Himalayas from Nagaland, India to Hainan Island in China.

They live in forests in the highest mountain regions (2920 miles, 4700 km) that have extremely low temperatures and thin air to which they are well adapted. No other monkey is able to live at such high altitudes.

They have a genetic adaptation that allows them to handle a low amount of oxygen. The nose of these monkeys has a unique appearance as if it is missing. They mainly eat lichens and moss growing on trees.

There are two main species: R. bieti and R. roxellana. A third, the Myanmar Snub-Nosed Monkey (Rhinopithecus strykeri) was discovered in 2010.

It’s now known that the Myanmar Snub-Nosed Monkey is not a distinct species, but rather it lives within the range of the Black Snub-Nosed Monkeys. The two are so similar that genetic analysis has shown they are actually subspecies of each other.

Black Spider Monkey

The Spider monkey is one of the largest types of monkeys that live in the tropical forests of Central and South America. Because they are so large they are often hunted and eaten by people. They have very long limbs, especially their arms, which is why they are named after their (very) distant insect relative…

The hands and feet also have opposable thumbs and big toes that help them to climb through trees with ease. They also rely heavily on their long, strong tails for balance and to grab onto branches during climbing. They live very high up (98 ft, 30 m) in the rainforest trees.

Spider monkeys are very social and forage in groups for fruits and other plant material. These are the smartest types of New World monkeys.

Colombian Red Howler

The Colombian red howler monkey is found throughout the rainforests of Colombia, Venezuela, Equador, Brazil and Peru.

Their fur is reddish-brown in color but this changes as they get older. Their long tail has no hair at the bottom so they can grab onto branches better.

The incredibly loud howling sound they make can be heard for several kilometers (3 miles, 5 km) across the rainforest to communicate with different groups that are far away. Singing is mostly done early in the morning when they start to move around to find new feeding areas.

The purpose of this is to chase other groups away so they will have less competition for food. Leaves are the most important their diet. Groups have one dominant male and several females. These monkeys prefer to walk rather than jump between trees.

They have a white face and body with black hair on their head. They often hold their tail in a round, curled position. It lives in large groups in the wild.

They eat fruit, nuts, insects, and other small animals.

They are very smart and have been observed to use tools to get to food and rub certain leaves over their bodies as a way to self-medicate. Sometimes they mix with groups of howler monkeys and have been seen grooming their fur.

The common marmoset is found in the rainforest of South America. They are a very small type of monkey with claws instead of nails, and their fur is a light brown color with white tufts on their ears. They eat fruit, fungi, bird eggs, insects, and other small animals.

Often they bite holes into branches and lick the sap or resin that seeps out of the tree. This is a reliable source of food when there are no fruits or insects to find.

Common Marmoset monkeys jump around between trees in a similar way as squirrels do, and live in small family groups where they help raise each other’s young. Two tiny non-identical twins are often born that firmly grasp onto their mother’s coat, who will carry them around.

Crab-eating Macaque

The crab-eating macaque is found in Southeast Asia. They have rough, tan fur and a pink face. Crab-eating macaques live together in groups with dominant females and have complex social interactions and ways to solve conflicts.

Crab-eating Macaques are mainly opportunistic in their choice of food, but enjoy eating crabs (hence their name!) and other seafood like shrimp and clams. Occasionally they use tools to get to food and can store this in their cheek pouches like hamsters.

Crab-eating Macaques have lived alongside people for a very long time and are considered pests by some and sacred by others. These monkeys often reside in temples where they are being fed by tourists. They are also used in the illegal pet trade and for scientific research.

Their cousins, the Pigtailed macaque is trained by humans to pick coconuts!

People have transported them to many different areas in the world where they did not use to occur, which is often problematic for the animals and plants there that they then eat or destroy.

Although they may look a bit frightening, they are usually not aggressive towards humans and they themselves are eaten by servals, leopards, and hyenas.

They are also called bleeding-heart monkeys because of a red patch of skin on their chest. When females are ready to reproduce their patch becomes darker red with bumps.

They live on the ground, are herbivores and graze mainly on grasses. They use their extra strong and small fingers to help them pull grass from the ground to eat.

Gelada monkeys live in complex social groups of up to 10 individuals and they have a very interesting social structure. For example, the females are dominant over the males in groups which is unusual for most types of monkeys. Females also have very strong social bonds which are usually between females and their young offspring but can include other members as well.

Golden Lion Tamarins have claws instead of fingernails that help them climb up the sides of tree trunks. These monkeys sleep a lot and do this in different nests each day to avoid predators. Early in the morning, they go out to search for fruits and they switch to eating insects in the afternoon, which they search for in bromeliads, vines, lianas, and hollow trees.

Golden Lion Tamarins are important dispersers of the seeds that are found in fruits they eat, helping plants to move to new areas of the forest. They are mainly monogamous, often give birth to twins, and live in small groups.

They have a characteristic crest of hair on their heads and are the smallest species of baboons. The males have particularly long canines. Their limbs are adapted to be able to walk long distances on the ground but they sleep in trees or other high places at night to avoid lions and hyenas.

When they forage for food, they do this in pairs of males and females together to provide protection to the females. They are omnivores that can live off a lot of different foods that they find on the ground. They dig in the ground to find water.

Guinea Baboons can occur in very large groups. They are not very aggressive amongst each other, especially the males who do not have a clear hierarchy.

Guatemalan Black Howler Monkey

Howler monkeys are the loudest animal in the world. Their extremely loud voice is used to attract females and scare off other males. These monkeys are the largest type of Howler and live in the lowland tropical rainforests of South and Central America where they avoid riverbanks.

The Guatemalan Black Howler Monkey is very picky with its food and never eats any insects or other animals. They have adapted to mainly eat leaves, but since these do not contain a lot of energy they cannot be very active, so they sleep a lot during the day.

They live in groups with one dominant male and several females, but the females raise their young by themselves.

They belong to the Alouatta genus of monkeys. These monkeys can be found in the Neotropical regions of Central and South America. The Guatemalan Black Howler monkey is the largest of the Howler monkeys and weighs up to 30 pounds (males).

Japanese Macaque (Snow Monkey)

The Japanese macaque is found in the forests of Japan. They have thick, light brown fur and distinctive red face. They are also known as “snow monkeys” because they live in cold, mountainous areas. They have discovered that they can deal with the cold by bathing in warm thermal pools.

They love to soak in these and the young ones can often be seen playing and jumping in them. This is a popular tourist attraction. Their coats are very thick which helps them to handle temperatures of as low as -20 degrees celsius (-4 F). Groups are led by dominant females.

They are very smart and have been seen to wash potatoes in seawater before eating them to give them a salty taste. Other monkeys copied this behavior and it was passed on through several generations. Some have even been seen to make snow balls for fun!

To heat themselves in the winter, they swim in the natural Japanese hot springs!

It is named for its tail that looks like a lion’s tail. It spends most of its life in trees, hiding away from humans.

The lion-tailed macaques live in groups and eat fruit, leaves, flowers, seeds, insects, and small vertebrates such as lizards. They can store food in their cheek pouches. When they are in a calm area where they can eat they rub their hands on their cheeks to release the food into their mouth and eat it.

They have 17 different calls that they use to communicate with each other. Dominant males stick their tails in the air to signal their position in the hierarchy.

The Mandrill

The Mandrill is the world’s largest and heaviest monkey and is found in the forests of Africa. They have reddish-brown fur, and their face is covered in brightly-colored skin which can change color depending on their mood.

They are not related to baboons even though they look somewhat similar. Mandrills typically live in troops of 20 individuals but have been seen in groups that contain up to 1300 individuals, the largest group of primates ever recorded.

The color of the mandril’s face and rump is indicative of its placement in the group hierarchy, with brighter colors leading to a higher status. They are omnivores that eat a lot of different things, even including other vertebrates like small Antilope, but they prefer fruits.

They themselves are eaten by pythons, eagles, and leopards. They spend the most time on the ground and sometimes climb trees.

Many of you may know this type of monkey already as the Mandrill named Rafiki in the “The Lion King” movies.

Proboscis Monkey

The Proboscis monkey is only found in Borneo, and it’s named after its large, drooping nose. The male monkeys’ noses can get to be about the size of their entire face! The males with the largest noses are able to make louder honking noises, making them more attractive to the females.

They are usually made fun of and referred to as “Dutch monkeys” by the native people of Borneo as resembling the white, fat, red-nosed sailors that arrived from The Netherlands during the colonization of Borneo.

Unlike most other types of monkeys, this type is mostly herbivorous, and it mainly eats young leaves, shoots, and unripe fruits. Their bellies are very big so they can ferment the leaves. They live in the mangrove forests near the rivers and have webbed toes, possibly for swimming. They are one of the largest types of monkeys in Asia.

The babies have a blue face for the first few months after they are born. They live in groups with dominant males but are not very territorial towards other groups living in the same area, probably because there are plenty of leaves to eat.

Pygmy Marmoset

The Pygmy marmoset is the world’s smallest monkey – and maybe the cutest? Pygmy marmosets are usually about six to seven inches long, and they typically weigh only about four ounces.

They are also known as “finger monkeys” because of their pronounced fingers that look almost like the finger of a human and because they have the size of a human finger when small!

Although, strictly speaking, they are actually more related to lemurs than monkeys.

They are found in the rainforests of South America, and their habitats cover parts of Brazil, Bolivia, Ecuador, Peru, Colombia, and Venezuela.

They prefer forests near rivers and specialize in eating gum from trees by biting in the bark and licking it when it oozes out.

This then attracts butterflies that they also like to eat. They live in small groups with dominant males and several females that give birth to twins twice a year. They all take part in raising the babies.

Despite its tiny size, it can jump up to 17 feet and has the ability to twist its head at 180-degree angles!

Red-Shanked Douc

The Red-shanked Douc is one of the most colorful monkeys and comes from the rainforests of Southeast Asia. They are mostly arboreal, and they usually live in small groups of up to six individuals.

They sometimes come down to the ground to eat dirt with minerals and salt. The tail cannot be used to grasp onto branches and is only used for balance. These monkeys prefer to communicate with each other via facial expressions rather than sound.

They mainly eat leaves that have a lot of fiber which they break down in their large stomachs by using bacteria that ferment it. Females will help each other with raising the babies and sometimes even breastfeed others young.

Rhesus Macaque

The Rhesus Macaque is a very common type of monkey that lives in many Asian countries in a wide variety of habitats. This breed can live up to 30 years and it is commonly used for scientific research. It has helped with many scientific breakthroughs, such as the invention of many vaccines and medications for HIV.

This monkey has even been to space in a rocket! It is also the type of monkey most commonly used in circus performances. In the wild, they live in social groups of around 38 individuals that are led by dominant females. They eat a lot of different plants and insects.

Roloway Monkey

The Rollaway monkey is an endangered type of monkey that lives in a small area of the tropical forests of western Africa. They need intact forests without human disturbance and where they can hide well. It is often eaten by people and therefore threatened. Groups have one male and several females with young.

This type of monkey has dark brown fur that is almost black. However, its stomach is lighter in color and it has a white patch of fur on the chest. They live high up in the trees where they eat a variety of plants and small animals. It runs away when there is danger and is therefore very hard to observe and we know very little about them.

Slow Loris

Slow Loris Monkey can kill you with its armpits!

The Slow Loris is a primate that lives in the tropical forests of Southeast Asia. They have brown fur and big, dark eyes. Because of its cute looks and very mild temperament, it is often illegally held as a pet but does not do well in captivity at all.

However, when they are scared they raise their arms and rub a toxin on their attacker that is produced by glands in their armpits. This gesture may be mistaken for an attempt to greet you with a hug, but is intended quite oppositely to harm you!

They can also bite to deliver a different toxin that is produced in their saliva. They are the only toxic primates. The toxin is comparable to the protein that causes cat allergies but has been fatal to people that went into anaphylactic shock.

They move extremely slowly, hence their name. They are only active at night. They eat fruit, gum from trees, and small animals and they forage alone. Slow Loris raises their young together and carries the baby around on their back in turn.

Aye-aye “monkey”

The aye-aye is actually a lemur, but I have included it because it is a very interesting example of a nocturnal funny-fingered primate!

The Aye-aye is only found in a small part of the rainforests of Madagascar. They have long, bushy tails and big ears. They are the largest nocturnal primates, meaning they are most active at night. During the day they sleep in round nests made of leaves in the treetops.

They live alone in the trees and mark their large territories with scent. They jump from tree to tree like squirrels. They use their big ears to listen for insects inside trees that they can eat.

Aye-ayes are also known for their strange fingers that each has different lengths and widths. These nifty digits function as a highly specialized toolbox for extracting different types of insects from different kinds of tree bark.

The Aye-aye rapidly tap the trees with their fingers and listen for an echo caused by the hollow chambers that insects make in the wood.

They then use their teeth to make a hole in the bark and use their fingers to extract the insects that are buried deep inside.

This unique feeding method is called percussive foraging. They are classified as endangered animals because they are killed because of their scary appearance and the destruction of the rainforest and may go extinct if nothing is done to preserve them.

Apart from eating insects, they are also one of the few primates known to eat coconuts.

The two major types of monkyes: Old and New world monkeys

When we look at the types of monkeys that we know of today, there are two major groups to consider: Those from the “Old World” and those of the “New World”.

The “New” and “Old” in these designations refer to the time when the continents of the world were “discovered”. It basically refers to South and Central America as the new world and the rest of the world as the old world.

New World Monkeys

New world monkeys are the types of monkeys that are found in the “New World” of South and Central America. These monkeys are also known as platyrrhines.

There are around 150 species of New World monkeys that have been identified to date including capuchin monkeys, spider monkeys, and howler monkeys.

New world monkeys have flat noses and nostrils which face sideways instead of forwards like the nostrils of the Old World monkeys.

Old World Monkeys

Old world monkeys are the types of monkeys that are found predominantly in Africa, Asia, and some parts of Southern Europe. These types of monkeys are also known as “catarrhines”.

Old-world monkeys have their nostrils facing forwards just as humans do.

Similarities between Old World and New World Monkeys

Despite their different habitats, living conditions, and diets, there are a number of similarities that Old World and New World monkeys share.

Both Old World and New World monkeys are highly intelligent, adaptable, and resourceful animals. They are both diurnal (active during the day) and arboreal (live in trees). They both have nails instead of claws which help them grasp tree branches and climb up and down trees.

New World monkeys and Old World monkeys also both live in extended family groups which may consist of several male members, several female members, and their offspring.

Differences between Old World and New World Monkeys

While similar in more ways than they are different, there are a number of important differences which separate Old World and New World monkeys:

  1. Old world monkeys have a more slender build compared to New world monkeys which tend to be stockier in build.
  2. Some New World monkeys also have a different set of teeth. They have three premolar teeth whereas Old World monkeys only have two premolars, resulting in old world monkeys having 32 teeth and Some New World monkeys like the capuchin or howler monkeys having 36 teeth!
  3. The New Woeld monkeys belong to the suborder of Platyrrhini which litterally means “broad nose”, and their broad and flat nose is another distingushable trait that sets them apart from the Old World monkeys.
  4. Old world monkeys have more prehensile (gripping) feet than New World monkeys. This means that Old world monkeys can hold things (branches etc.) in their feet whereas New World monkeys cannot.
  5. Old world monkeys do not have prehensile tails like New World monkeys do. Instead, Old world monkeys have tails which help them balance when they are moving around on thin branches.
  6. New World monkeys do not have thumbs, but Old World monkeys do. This means that New World monkeys are unable to hold onto objects properly which makes life in the trees more difficult for them.
  7. New world monkeys spend more time on the ground than Old world monkeys who are more inclined to live in the trees, but it is thought that this is because New world monkeys tend to live in areas where the trees do not grow as tall as those of the Old World.

Maybe you can already tell from these differences, whether your favorite monkey is from the “Old” or “New” world? If not, I have included two lists of all monkey species belonging to each type at the end of this article.

What about Gorillas, Chimpanzees and Orangutans?

So now that we went through some of the most amazing monkeys on earth, you may be wondering where those big chest hammering, three swinging, tool-using primates are on that list? Well, then you are thinking about apes, not monkeys

But what’s the difference?

Are apes and monkeys not the same?

No. Apes and monkeys are not the same. Monkeys and Apes are both primates and share a common ancestor that lived  25 to 30 million years ago.

Maybe you have heard that we humans are not monkeys but are closely related genetically. This is because our grand, grand, grand (repeat ~100000 times) parents looked more like a chimpanzee than you do. I hope…

However, “ape” is sometimes used as another word for “monkey” but this is not scientifically correct. Apes do indeed belong to the larger group of primates to which monkeys also belong, but they are quite different (being one myself, I speak from experience…).

Apes (Hominoidea)

The group of Apes includes Gibbons, Chimpanzees, Orangutans, Bonobos, Gorillas, and our own species (humans)! All apes are quite intelligent, and they have the ability to use tools, make decisions for themselves, and solve problems.

Gibbon

The Gibbons are a group of apes that live in the rainforests of Southeast Asia and parts of China.

Contrary to the other apes listed here, they belong to the group of “lesser apes” (Hylobatidae) that are smaller and spend most of their lives climbing trees. Gibbons are very active, and they are capable of swinging and leaping from tree to tree at impressive speeds.

Gibbons also differentiate themselves from the other great apes by forming stable mating pairs, rather than adhering to the more loose partner ethics of their great ape cousins.

They mainly eat fruit, however, they also occasionally supplement their diets with leaves, flowers, insects, and the eggs of smaller birds.

Orangutan

The Orangutan is a type of ape that lives in the rainforests of Borneo and Sumatra. These apes are the largest living arboreal animals. They have reddish-brown hair, and their faces are covered in long white fur. Orangutans are very intelligent, and they are known for being able to use tools and solve problems.

Chimpanzee

The Chimpanzee is a type of ape that lives in the rainforests of Africa. Chimpanzees are the most common type of ape, and they are known for being highly intelligent and social animals.

Gorilla

The Gorilla is a type of ape that lives in the rainforests of Africa. Gorillas are the largest living land animals on Earth. Male gorillas can weigh up to 400 pounds, and females can weigh up to 200 pounds! They have black fur, and their faces are covered in long silver hair. Gorillas are very social animals, and they live in groups that can number up to 50 individuals.

Bonobo

The Bonobo is a type of ape that lives in the rainforests of the Democratic Republic of Congo. Bonobos are very similar to Chimpanzees, however, they are considered to be more peaceful and less aggressive than their cousins. They use tools, make decisions for themselves, and solve fairly complex problems.

Humans

Well, you know this animal I assume… We, as humans, are the most adaptive type of ape that has managed to colonize almost the entire planet! Humans are the only species in the group of Apes that can speak.

We are also separating ourselves from the remainder of apes by being highly intelligent and having the ability to use advanced tools, think abstract thoughts, and solve abstract and complicated problems.

What are the main differences between Apes and Monkeys?

The main difference is that apes are more intelligent and can use tools, while Monkeys cannot.

This is due to the bigger brains of apes compared to monkeys. The more complex brain also allows apes to communicate, which allows them to form more complex social groups than monkeys do.

Other anatomical differences between apes and monkeys include:

  1. A tail – monkeys have tails and apes do not!
  2. Apes have larger and heavier bodies.
  3. Apes have the ability to walk upright using only their hind legs.
  4. They also tend to move around threes by swinging rather than climbing.
  5. Apes have appendixes, while monkeys don’t.

To understand how apes and monkeys are related, we need to look into the two groups or types of currently living monkeys. These are divided into the “new world” and “old world” monkeys and the apes diverged from the Old World monkeys approximately 27 million years ago.

What types of monkeys live in Australia?

There are no monkeys that live in Australia. The closest monkey to Australia would be the Rhesus Macaque, which is found in Asia.
However, there have been some cases of Rhesus Macaques being brought over to Australia illegally and then released into the wild. So it is possible for monkeys to live in Australia although there are not originally from there.

What types of monkeys live in Europe?

Only the Barbary Macaque lives outside of Zoos in Europe. They live on the rocky cliffs of Gibraltar in Southern Europe.

What types of monkeys live in Hawaii?

Although the Islands of Hawaii are tropical and seem ideal as a monkey habitat, no wild monkeys currently live in Hawaii.

What types of monkeys live in Nepal?

The following types of monkey live in Nepal: the rhesus macaque, Hanuman langur and stump-tailed macaque. The first two breeds are found throughout most of Nepal, while the stump-tailed macaque is only found in the southern part of the country. All three of these breeds are considered sacred in Hinduism.

What types of monkeys live in North America?

There are no native monkeys that live in North America, however, there are invasive species of Rhesus Macaque monkeys that live in smaller colonies in Florida and Morgan Island, in South Carolina.

The closest wild monkey to the continent would be the monkeys of Central and South America.

What types of monkeys live in South America?

The following types of monkey live in South America: the squirrel monkey, the common marmoset, the capuchin monkey, the howler monkey and the spider monkey. The squirrel monkey is found in the tropical rain forests of Brazil. Common marmosets, capuchin monkeys and howler monkeys are only found in the Brazilian rain forests as well (though capuchins can also be found in parts of Venezuela). The squirrel monkey is a small species that usually weighs around 150g.

The common marmoset lives mainly outside on branches high off the ground, while the capuchin monkey is a very social species that lives in large groups. The howler and spider monkeys are both arboreal (tree-dwelling) creatures, with the latter being able to move around on all fours as well.

What types of monkeys live on the island of Madagascar? 

While no actual monkeys live in Madagascar, there are other primates in the form of lemurs that look and behave like monkeys.

The following breeds of lemurs live on the African island of Madagascar: the ring-tailed lemur, black lemur, white-fronted lemur, red-ruffed lemur, and brown lemur.

The most common and widely distributed species of lemur in Madagascar is the ring-tailed lemur, which has a black body with white rings on its tail. The other breeds of lemur that live on the island are smaller and less numerous than the ring-tailed variety.
