Where Do Monkeys Live?

Monkeys can be divided into two geographically distinct groups – New World Monkeys (Ateloidea species) and Old World Monkeys (Cercopithecoidea species).

New World Monkeys

New World Monkeys are native to Central and South American countries and include the Spider, Red Howler, Squirrel, Saki, Saddleback Tamarin, Lion Tamarin, Owl, Marmoset, Titi, and Ukaris. Most species of New World monkeys are characterized by a prehensile (or grasping) tail that can be used like a hand, and this extra limb facilitates their existence as exclusively arboreal, spending their lives in trees. (These tails have a bare patch of skin that can grip like the palm of your hand.) 

Research has shown that there is no living form of a New World Monkey, nor any evidence of a fossil form, to indicate that these creatures habitually come to ground level in normal behavioral patterns. It should be noted that monkeys, in their arboreal existence, use all four limbs to leap from tree to tree, and are known to run along branches rather than swinging arm over arm like apes.

In addition to New World monkeys’ adaptation to trees, a few of these primates possess additional adaptations-i.e., the Saki that inhabits mountainous terrains of South America and has a coarse fur that keeps it dry during the region’s frequent downpours. The Woolly, another of the New World species that lives in the Amazon rainforest and in the mountain ranges of Peru, has adapted to dwelling high up in tree canopies because of the wet and very hot climatic conditions.

With fruit, wild berries, leaves and nuts making up a large part of the New World monkey’s diet (also comprised of eggs, flowers and small animals and insects), the primate plays an important ecological role in the life of the rainforest by the dispersion of seed for many tree species.

Old World Monkeys

Old World Monkeys (including the Japanese Macaque, Rhesus Macaque, Gelada, Hamadryas Baboon, Hanuman Langur, Red Colobus, Black Colobus, Patas and Savanna Baboon) are a common sight on African and Asian continents. These primates exist in more varied habitats, as they are both arboreal and terrestrial (ground dwellers).

Old World Monkeys may indeed have a tail (ranging from short to long) but the appendage is usually nonprehensile. This “non-functioning” tail, however, does not preclude Old World primates from tree dwelling, as all possess adaptations for climbing trees.

One of the largest of Old World monkeys – the Baboon – is a ferocious ground-dwelling primate seen in Africa’s savannas, open woods, grasslands, rocky areas and dry lands. This primate is also common in similar areas on the Arabian Peninsula. 

The large  and powerful Baboon (as well as the similarly-sized Macaque which inhabits southern Asia) live mostly on the ground. As well, the Mandrill, a close relative of the Baboon, (residing in West African countries of Gabon, Cameroon and Congo) also lives on the ground, but sleeps in trees. These three terrestrial creatures (Baboon, Macaque and Mandrill) are endangered due to a loss of habitat.

While most Old World Monkeys live in African and Asian regions with forested habitats of tropical or semi-tropical latitude, there are a few of these creatures that exist outside of the tropics including the Japanese Macaque which lives in the mountainous region north of Honshu which is covered in snow for eight months of the year, and the Barbary Macaque which lives in the Atlas Mountains of Algeria and Morroco. Savannas (which are characterized by distinct wet and dry seasons with year-round warm climates) are home to some of the larger Old World terrestrial monkeys, such as Baboons (see above).

Monkey Habitats

In concluding a search to the query, “where do monkeys live?”,  it can be said for certain that monkey (Old and New World) habitat has been well established in regions across Africa, Asia and Central and South America. Their existence in the wild of Australia, North America or Antarctica is extremely rare.

In terms of climatic and ecological environments, it has been determined that rainforests (distinguished by heavy rainfall and relatively high temperatures) claim the majority of the world’s monkey population. However, because of their remarkable and varied adaptations, the characteristics of the monkey’s habitats can easily cross a range of extremes – from the hottest of tropical climates to cold and frosty environments - and from ground level dwellings up to the highest tree-top canopies and mountainous altitudes.  Some of these primates, such as the Rhesus Macaque, have even learned to utilize human-modified environment and are now living in cities. One environment where you’d hardly ever find a monkey, however, is in a swamp or wetland environment although they are known to be good swimmers.

Loss of habitat continues to be the biggest threat to the majority of the world’s wild population of monkeys. Destruction of rainforests, encroachment along forest fringes and indiscriminate logging practices all contribute to a dwindling environment in which these intriguing creatures can survive.

The ability to stop the destruction of these (and other important) habitats before it is too late is a challenge that we, as responsible world citizens, must all face now and into the future. For as it was so aptly stated by the late conservationist and naturalist John Muir, “when one tugs at a single thing in nature, he finds it attached to the rest of the world.” The sooner we humans get this message, the better for the preservation of the world’s environment and for those creatures, including monkeys, who dwell within.
