Types of Monkeys: Many things come to mind when you think monkeys. They are often considered to be cute and very intelligent animals. Many species have their characteristics regarding location, size, color, and even abilities.
Monkeys are very vocal animals, which is how they communicate. They emit different tones to protect themselves from danger, call a mate, and communicate with their young.
Monkeys consist of many species throughout the world. On this page, the BioExplorer team explores all types of monkeys in the mammalian world.

Frequently Asked Questions
What are the most common monkey?
The Rhesus macaque is one of the most common monkeys, especially in Asia. Found in diverse habitats, from grasslands to urban areas, they have a wide distribution. Another prevalent species is the Vervet monkey, native to Africa and known for its adaptability to various environments.
What is the most friendliest monkey?
The capuchin monkey is often considered the friendliest among monkey species. Renowned for its sociable behavior, intelligence, and playful nature, it frequently interacts positively with humans, making it a popular choice in the pet trade and entertainment industries. However, like all primates, they have complex needs and can be challenging to care for.
What is a monkey that starts with G?
A monkey that starts with “G” is the “Golden lion tamarin“. It’s a small New World monkey known for its bright reddish-orange fur and mane, resembling a lion’s. They are native to the Atlantic coastal forests of Brazil.
Suggested Reading:
Monkeys Starting with G
Explore all monkeys from the world of primates that start with the letter G, including Gray-Shanked Douc Langur, Golden-faced Saki, Geoffroy’s Saddleback Tamarin, Germain’s Langur, and more.
What are the two main types of monkeys?
The two types of monkeys are:
Old World Monkeys: Native to Africa and Asia, they include species like baboons, macaques, and colobus monkeys.
New World Monkeys: Found in Central and South America, they include capuchins, howler monkeys, and tamarins.
Old World Monkeys Vs. New World Monkeys
Old-world and New-world monkeys are two types of monkeys within Primates. Explore all differences between them from all aspects here.
How many types of monkeys are there in the world?
As of 2023, there are over 330 different species of monkeys in the world, classified into two main groups: Old World Monkeys and New World Monkeys.
Which is the smallest monkey?
The smallest monkey is the pygmy marmoset (Cebuella pygmaea). It weighs around 100 grams (3.5 ounces) and measures about 4.6 to 6.2 inches (11.7 to 15.8 cm) in length, excluding its tail. Native to the rainforests of the western Amazon Basin in South America, pygmy marmosets are known for their tiny size and distinctive vocalizations.
Monkeys vs. Monkies
Let’s get one of the fundamental confusion out of the way first. Is it monkeys or monkies?
When a noun word ends with “y”, there is always confusion as to whether the plural form ends with “ies” or “ys”.
Many English dictionary sources say the grammar rule is simple. When a noun ends with a vowel followed by y, the plural form gets an “s”; otherwise, it would end with “ies”.
For instance, the plural form of “Dictionary” is “Dictionaries”.
Based on that principle, the plural form of monkey is indeed monkeys.
First Grouping of Primates
An English biologist, St. George Jackson Mivart first published the classification of primates in his book ‘Man and Apes’ in 1873[1]. His categorization of monkeys was based purely on anatomical differences, habits, and geographical distribution. According to this book, the early classification of order Primates contained two sub-groups, namely:
- Group-1: Man, and all the apes, which were first called Anthropoidea.
- Group-2: All Lemurs and the animals most like them were called Lemuroidea; the creatures contained in it when spoken of being generally also termed “Half-apes” or “Lemuroids“.
Modern Grouping of Primates
After so many debates and further data collection and analyses and discoveries of new monkey species over a century, another British-born biological anthropologist, Robert D. Martin, currently a curator at Chicago Natural Museum, has published an excellent book called “Primate Origins and Evolution: A Phylogenetic Reconstruction” in 1994[2]. This research attempted to classify living primates into 6 different sub-groups based on geographical importance.
| 1 | Lemurs | Madagascar | |
| 2 | Lorises and bushbabies | Africa and Asia | Prosimians |
| 3 | Tarsiers | Southeast Asia | |
| 4 | Marmosets, Tamarins, Capuchins, Squirrel monkeys, Owl monkeys, Titis, Sakis, and Howlers (Ceboidea) | South and Latin America | New World Monkeys |
| 5 | Talapoins, Guenons, Baboons, Colobus, Macaques, Vervets, Geladas, Mangabeys, Langurs, Mandrills, Surili, Patas, Proboscis Monkeys (Cercopithecoids meaning “elongated apes“) | Africa and Asia | Old World Monkeys |
| 6 | Apes and humans (Hominoids) | Africa and Asia | Apes |
This primate grouping is based on grade or level of organization, and in no way does it implies any superiority or inferiority between them.
According to the fossil study in Tanzania by paleontologists in 2013[3], it became evident that the old-world monkeys (baboons, macaques) and apes (humans & chimpanzees) were already separated 25 million years ago!
Classification of Primates
Here are 4 major types of primate and their characteristics:
Prosimians
The earliest primates that roamed the earth about 25 million years before monkeys evolved were Prosimians, meaning “pre-monkeys” or “proto-primates”.
- These prosimian species live today, including lemurs, lorises, tarsiers, aye-aye, and bush babies. The prosimians were classified into order Primates mainly because their hands with flexible fingers and opposable thumbs made it possible to fetch things up.
- Most prosimians rely heavily on a sense of smell for communication and finding food. With the tarsier, eyesight has become more critical as it can swivel its head 180 degrees in each direction. On the other hand, the apes and monkeys rely primarily on their sight.
Today, Prosimians live in some parts of Asia and Africa, especially Madagascar. No prosimian species are found in the Americas or Australia.
Old-World Monkeys
Old World Monkeys are a mixed group of primates with varied body sizes (medium to large-sized), habitats, diets, social behaviors, and anatomical differences.
- All Old-World monkeys are classified under two families: Cercopithecinae and Colobinae.
- Unique characteristics-wise, Old-World monkeys have downward-pointing nostrils, tend to stay mainly on the ground than trees (non-arboreal), and have a simple digestive system with cheek pouches for plant matters. Also, these primates have a tail which makes them different from apes.
- The Old-World monkeys hail from various countries in South and East Asia, the Middle East, and Africa, except for Madagascar.
New-World Monkeys
New World monkeys are a varied group of small to medium-sized arboreal (i.e., living on trees) primates.
- These primates are restricted to the tropical forests of Southern Mexico and Central and Latin America.
- Taxonomically, New World monkeys are classified into two prominent families Cebidae and Callitricidae.
- Exclusive attributes-wise, these kinds of monkeys are primarily herbivores, twin births, and no-cheek-pouches unlike Old-World counterparts, and some have a prehensile tail (Spider monkeys).
Apes
Apes are another clade of old-world monkeys collectively called Hominoidea, native to Africa and Southeast Asian countries.
- Apes do not have tails (except L’Hoest monkey – a great ape) due to the mutation of the TXBT[4] gene cell.
- Also, apes cannot perform brachiation (arm swinging in the arboreal movements on tree tops, unlike the other three kinds listed above).
- There are two main branches of apes: gibbons (“lesser apes”) and hominids (“great apes”). Orangutans, gorillas, chimpanzees, and bonobos are examples of greater apes, whereas the lesser apes contain all types of gibbons, including Lar gibbon, Agile gibbon, Silvery gibbon, and more.
Hominoids are swift tree climbers except for gorillas and humans. Apes feed on various plants such as fruits, leaves, stalks, seeds, roots, and small animals.
