Primates are a fascinating group of animals. They include monkeys, apes, and lemurs.
They are all members of the order Primates and can be found in different parts of the world.
There are many different primates, each with unique adaptations and behaviors.
With their unique characteristics and interesting behaviors, primates are one of the world’s most studied groups of animals.
This blog post will introduce you to the different types of monkeys and provide some basic information about them.
We’ll also discuss the importance of Monkeys in their natural habitats and what we can do to help protect them.
Stay tuned for an enlightening look at the world of primates!
How Many Types of Monkeys Are There?

There are more than 260 species of monkeys in the world.
That said, most monkey species can be classified into two groups: Old World monkeys and New World monkeys.
Old World monkeys are found in Africa and Asia, while New World monkeys are found in Central and South America.
The two groups are further distinguished by their physical characteristics and behaviors.
For example, Old World monkeys are catarrhines (Meaning they have nostrils that point downwards), while New World monkeys are platyrrhines (Meaning they have nostrils that point outwards).
Old World monkeys also tend to be larger than New World monkeys.
Within these groups, there are many different species of monkeys. Here are a few examples:
Types of Old-World Monkeys
Old World monkeys all belong to the same family: The Cercopithecoidea family.
This family includes some of the most well-known monkey species, such as the:
- Macaque
- Baboon
- Gibbon
- Red-shanked douc
- Langur
- Colobus monkey
- Mandrill
- Guenon
- Howler monkey
- Tamarind
- Patas monkey
- Proboscis monkey
Types of New World Monkeys
New World monkeys are classified into five families: Callitrichidae, Cebidae, Aotidae, Atelidae, and lastly, Pitheciidae.
The Callitrichidae family includes marmosets and tamarins, while the Cebidae family includes capuchins and squirrel monkeys.
The Aotidae family includes the night monkeys, while the Atelidae family includes the howler, spider, and woolly monkeys.
The Pitheciidae family consists of the titi, uakaris, and saki monkeys.
Although there is some variation among these families, New World monkeys share some standard features.
For example, they are all prehensile, meaning they can grasp objects with their tails. This adaptation is helpful for life in the trees.
Now, let’s take a closer look at some of the most exciting monkey species worldwide.
1. The Pygmy Marmoset: The World’s Smallest Monkey

The pygmy marmoset (Callithrix pygmaea) is native to the rainforests of South America. It is one of the smallest primates in the world, with an average body length of only 5-6 inches (12-15 cm).
The pygmy marmoset is a vocal monkey. It communicates with various sounds, including clicks, chirps, and trills.
This species is also unusual because it is the only known monkey to give birth to twins.
The pygmy marmoset is an endangered species due to habitat loss and hunting.
2. The Mandrill: The World’s Most Colorful Monkey

The mandrill (Mandrillus sphinx) is a giant Old-World monkey.
It is native to the tropical rainforests of Central and South-Western Africa.
The mandrill is the most prominent member of the mongoose family.
It has an average body length of 3 feet (90 cm) and can weigh up to 77 pounds (35 kg).
Mandrills are easily recognizable by their bright colors and distinctive facial features.
The males have large, colorful noses and are much more brightly colored than the females.
The mandrill is an omnivorous species. It feeds on various fruits, leaves, insects, and small vertebrates.
The mandrill is classified as vulnerable by the IUCN Red List. The main threats to this species are habitat loss and hunting.
3. The Gelada: The World’s Only True Grass-Eater

The gelada (Theropithecus gelada) is a giant Old-World monkey. It is native to the Ethiopian Highlands.
The gelada is the only primate that is classified as a true grass-eater. Around 85% of its diet consists of grass.
The gelada is a social monkey. It lives in groups of up to 500 individuals. Within these groups, there is a strict hierarchy.
Males are at the top of the hierarchy, followed by females and their young.
Geladas communicate with each other using a variety of sounds, including grunts, screams, and bleats.
The gelada is classified as endangered by the IUCN Red List. The main threat to this species is habitat loss.
4. The Proboscis Monkey: The World’s Largest Nose

The proboscis monkey (Nasalis larvatus) is a giant Old-World monkey. It is native to the island of Borneo.
The proboscis monkey gets its name from its large nose. The male’s nose can grow up to 7 inches (18 cm) long!
Proboscis monkeys are good swimmers. They often travel between trees by jumping into rivers and swimming to the other side.
This species is also notable for its loud, honking call. The probosci’s monkey is an endangered species due to habitat loss and hunting.
5. The Japanese Macaque: The World’s Snow Monkey

The Japanese macaque (Macaca fuscata) is a medium-sized Old-World monkey. It is native to the island of Japan.
The Japanese macaque is known as the “snow monkey” because it lives in cold, snowy habitats.
It is the only non-human primate known to survive in such a climate.
Japanese macaques are social animals. They live in groups of up to 200 individuals. Within these groups, there is a strict hierarchy.
Males are at the top of the hierarchy, followed by females and their young.
Japanese macaques communicate with each other using a variety of sounds, including screams, barks, and grunts.
The Japanese macaque is not considered to be endangered at this time.
As you can see, there is a great deal of variation among the different types of monkeys worldwide.
Each species has its unique features, habitat, and diet. But one thing that all monkeys have in common is their fascinating world of primates!
What is the Importance of Monkeys in Their Natural Habitats?

Primates, including monkeys, are an essential part of the delicate ecosystem.
They help keep nature balanced by dispersing fruit and regulating the populations of animals they prey on.
In addition, they are a vital food source for many other animals, such as large cats, snakes, and birds of prey.
The ecosystem would be out of balance without monkeys, and many other animals would suffer. The loss of even one monkey species can devastate the local environment.
Therefore, we must do our best to protect these amazing animals and their habitats.
By learning about the different types of monkeys and their importance in the wild, we can help to raise awareness and make a difference!
