Old World Monkeys is a name for a family of primates in the family of Cercopithecidae. They include baboons, red colobus, macaques, etc. These monkeys show different characteristics and physical features. Talapoin is the smallest, while male mandrill is the largest. Baboons are terrestrial, while colobus monkeys are arboreal. Some Old World monkeys have flat noses while others have snouts. Besides, most have tails, which may show coloration. We mostly find them in shrublands, savannahs, mountainous regions, and tropical rain forests of Africa and Asia. These land animals are omnivorous and opportunistic, capable of snatching food from your hand.

What is the difference between the Old World and New World monkeys?

New World monkeys are found in America. They have a prehensile tail, enabling them to climb trees faster. They also have a high rate of reproduction and a shorter lifespan. Old World monkeys, on the other hand, are usually large and have a downward-pointing nostril, two premolars, and a non-grasping tail. Besides, we can find Old World monkeys in Africa and Asia.

Why do Old World monkeys have tails?

The tails of Old World monkeys are just for providing balance and support when moving among trees and during feeding, but not for grasping or holding an object or food like those of New World monkeys. Some species of Old World monkeys have long tails and others have short tails.

What do Old World monkeys typically eat?

Old World monkeys are browsers. Their diet includes fruits, flowers, leaves, rhizomes, insects, and even small mammals. Apart from these, they can also eat handouts and even garbage. This partial omnivore feature makes them easily adaptable to most environments. Thus, you can easily find them in zoos or people’s houses as pets.

Patas Monkey (Erythrocebus patas)
Comparison drawing of the Patas Monkey compared to similar Old World Monkey species at scale

The Patas Monkey (Erythrocebus patas) is a species of primate native to Africa. They are have an orange-brown coat with a white underside and a grey mane. They also have cushioned bottoms that makes sitting more comfortable, like portable seat cushions. Patas monkeys live in the grasslands and savanna of central Africa. Unlike many other primates, they prefer to live in the open, and use the tall grasses of the savanna to hide from predators instead of trees. It also helps that they are the fastest primates in the world and can reach speeds up to thirty-five miles per hour.

Patas Monkeys have a head-body length of 19.3”-34.6” (49-88 cm), tail length of 18.9”-28.3” (48-72 cm), height on all fours of 16.5”-29.5” (42-75 cm), and body width between 5.5”-9.8” (14-25 cm). The typical weight of the Patas Monkey is in the range of 14.3-27.5 lb (6.5-12.5 kg). Patas Monkeys have lifespans between 15-24 years in the wild and 20-30 years in captivity.

Lion-Tailed Macaque (Macaca silenus)
Drawing comparing the size of the Lion-Tailed Macaque to similar Old World Monkey species

The Lion-Tailed Macaque, or wanderoo, (Macaca silenus) is a primate native to India. They are named after the tuft of fur at the end of their tail which bears resemblance to the tuft on a lion’s tail. They are also identifiable by their silver mane around their faces. It is this mane that led the Germans to call them ”bearded monkeys”. Lion-tailed macaques are omnivorous but prefer fruit to anything else. They live in the tropical forests of the Western Ghats mountains in southwestern India, and are arboreal, meaning they live their entire lives in the upper canopy of the forests.

Lion-Tailed Macaques have a head-body length of 16.5”-24” (42-61 cm), tail length of 9.8”-15.4” (25-39 cm), height on all fours of 13”-18.1” (33-46 cm), and body width between 7.9”-11” (20-28 cm). The typical weight of the Lion-Tailed Macaque is in the range of 6.6-22 lb (3-10 kg). Lion-Tailed Macaques have lifespans between 20-30 years in the wild and 30-35 years in captivity.

Proboscis Monkey (Nasalis larvatus)
Drawing comparing the size of the Proboscis Monkey to similar Old World Monkey species

The Proboscis Monkey (Nasalis larvatus) is a primate species native to Asia. They get their name from their large, bulbous noses. These noses are larger in the males, and may be used to amplify their calls and impress the others in their group. They live in the mangrove forests and lowland rainforests of the island of Borneo. They have webbing between their toes that helps them swim, an important adaptation since they live mostly on the coast and will leave their treetops to leap into rivers. They can swim up to twenty meters underwater without coming up for air.

Proboscis Monkeys have a head-body length of 20.9”-29.9” (53-76 cm), tail length of 20.5”-29.5” (52-75 cm), height on all fours of 16.1”-22.8” (41-58 cm), and body width between 8.7”-11.4” (22-29 cm). The typical weight of the Proboscis Monkey is in the range of 15.4-50.7 lb (7-23 kg). Proboscis Monkeys have lifespans between 15-20 years in the wild and 17-23 years in captivity.

Bonnet Macaque (Macaca radiata)
Drawing comparing the size of the Bonnet Macaque to similar Old World Monkey species

The Bonnet Macaque (Macaca radiata) is a small primate native to India. They are recognizable by (and named after) the tuft of fur on their head which looks like a bonnet. They are adaptable monkeys, and are found all over southern India, not only in the forests and prairies and mountains, but also in urban areas, including villages and temples. Some tourist areas even sell rice to tourists to feed them, attracting more monkeys and then more tourists. They’ll even riffle through human trash or steal from markets and temples to find a meal. They are strong swimmers and have strong color vision.

Bonnet Macaques have a head-body length of 13.8”-23.6” (35-60 cm), tail length of 18.9”-27.2” (48-69 cm), height on all fours of 11”-17.7” (28-45 cm), and body width between 5.1”-8.7” (13-22 cm). The typical weight of the Bonnet Macaque is in the range of 7.7-20 lb (3.5-9 kg). Bonnet Macaques have lifespans between 20-30 years in the wild and 30-35 years in captivity.

Mandrill (Mandrillus sphinx)
Scale illustration of an average Mandrill compared to other species of Old World Monkeys

The Mandrill (Mandrillus Sphinx) is a species of large primate native to equatorial Africa. Mandrills have brightly colored faces and just as brightly colored rumps. Their coloring not only labels them as attractive to their mates, but also helps them to follow each other through the dense and dark jungle. They are the largest of the Old World Monkeys in the world. Mandrills live in tropical rainforests, and while they mostly walk along the forest floor, their opposable thumbs allow them to climb all the way to the canopy. Much like pet hamsters, mandrills have cheek pouches for food storage. They eat fruits and nuts as well as small animals.

Mandrills have a head-body length of 21.7”-37.4” (55-95 cm), tail length of 2”-3.9” (5-10 cm), height on all fours of 20.5”-35.4” (52-90 cm), and body width between 9.4”-16.5” (24-42 cm). The typical weight of the Mandrill is in the range of 26.5-81.5 lb (12-37 kg). Mandrills have lifespans between 20-28 years in the wild and 32-40 years in captivity.
