Monkeys are tree-dwelling animals known for their high level of intelligence as they belong to the order of primates. Though they are mostly arboreal, some dwell on land in the savannas and mountainous regions, the baboon being a primary example. The Old World and New World monkeys are primarily distinguished based on their physical features, particularly the structure of their nose.

List
of Common Types of Monkey
Species
There are about 24 genera and 138 species of the Old World monkeys, while the New World monkeys possess 19 genera and 100 species categorized into four families. The Old World monkeys are named so since they inhabit the Old World, comprising of the continents of Europe, Africa, and Asia. The New World species are the ones native to North and South America.

Appearance and Physical Description
Size: The smallest species of monkeys are 6 inches long, while the bigger ones can have lengths of up to 36 inches.
Weight: The
average weight of monkeys vary between 4 ounces and 77 pounds.
Color: Though
brown and gray are the most standard colors, other shades include red, golden,
and white individually or in combination.
Nose: The Old
World monkeys have narrow noses with side-facing nostrils, while those
belonging to the New World are flat-nosed.
Tail: The tails
of the New World monkeys are long and grasping (prehensile), helping them to
get a grip on objects, while the Old World species have short, non-grasping
tails. There are also tailless monkeys like the Barbary macaques.
Legs: They have
two legs like humans but cannot walk solely on them. Instead, they take the support
of their big, black palm.
Distribution
They exist throughout the continents of Africa, Asia, South America, and Central
America.
Habitat
As mentioned above, most of them live on trees, while there
are also some ground-dwelling monkeys.
How
Long Do They Live
In the wild, monkeys live between 10 and 50 years on an average, whereas in captivity their lifespan could be longer. Bueno, a black spider monkey who passed away in 2005, lived till the age of
What Do They Eat
Their diet mainly comprises of nuts, seeds, fruits like bananas,
roots, and grass. Some monkeys are omnivores, as they also eat lizards, spiders,
and insects
Behavioral
Traits
These primates express their emotions and needs through various sounds like clicking, chattering, and yelling at a high pitch.
Another characteristic feature is that they display a strong fellow feeling. They help their mates by ensuring protection, sharing food, and caring for the little ones of other monkeys.
They often indulge in grooming one another by taking off debris and fur from the body of their fellow mates.
Adaptation
The long, prehensile tails help them to hang with ease from branches as well as get a firm grip on objects.
Their sharp molars help them to chew leaves with ease.
The skin around the genital areas of the females become swollen, turning bright red or pink during hormonal changes to indicate to the males that they are ready for mating.
Most of the Old World monkeys possess cheek pouches helping them to store food that they may eat later.
They have prominent olfactory receptors, which makes their smelling ability stronger, helping them to sense a threat with ease,
Reproduction
and Mating
They mature at the age of 4 or 5, with only a few of them mating in the first half of their life. Certain species are known to wash with urine to appear attractive to females. The babies are born after 160 days post-mating, and the mother shares an instant close bond with her young one. The life cycle of a monkey is similar to humans as it starts with gestation, proceeding to babyhood and finally, adulthood.
What
Do The Baby Monkeys Look Like
The baby monkeys have black furs at birth, the color of
which changes in three months, though this may vary from one species to the
other.
Conservation
Some of them are endangered, or even at risk of extinction, with certain species having a population of only 1,000 in the wild. The Tana River Red Colobus and the Tonkin Snub-Nosed belong to list of the 25 most endangered primates. The Hainan Black-crested Gibbon is critically endangered since only about 20 of them are left. Conservation efforts to keep a check on their population include protecting trees in their habitat range, as well as increasing awareness among people.
Some species like the proboscis monkeys, macaques, and snow
monkeys, possess the ability to swim.
5. Where do monkeys originally
come from?
It has been a topic of debate, with the common belief being that they belonged to Africa according to fossil evidence traced in Egypt. Recent studies, however, suggest Asia as their place of origin. The Proconsul is the first monkey genus to exist in the world.
