Monkeys

Monkeys are not just mischievous; they are strong-minded mammals in the World. As socially agile animals, they are known for their tactics, like leaping through trees. They can sit upright like humans and are playful creatures that look great when grasping peanuts, holding a stick, and climbing up trees. Monkeys are different from apes. Along with Intelligent Arboreal activity, they are one of the Senseless creatures of the World.

Different Families of Monkeys

Cladistically, monkeys are divided into two groups. These groups are known as Old World groups and New World groups. Twenty genres of Old and New World families comprise nearly 300 species. Further, these groups are divided into families.

Old World Monkeys:

It comprises only one family, Cercopithecidae, further divided into two subfamilies under 21 genera. Old World monkeys have 135 species.

New World Monkeys:

These are known as Platyrrhini. New World monkeys comprise 5 families present under 20 genera. More than 130 species of New World monkeys exist in the World.

Families of New World monkeys:

Callitrichidae: species 42 (marmosets and tamarins)

Cebidae: species 14 (capuchins and squirrel monkeys)

Aotidae: species 11 (night monkeys)

Pitheciidae: species 4 (titis, sakis, uakaris)

Atelidae: species 24 (howler, spider, and wooly monkeys)

Physical Characteristics

Size and Weight: Male monkeys are larger than males. Their sizes are about 15 to 28 inches. As a look, they are not much in weight. The smallest monkey weighs about 3 ounces, while the largest weighs about 75 pounds.

Noses: Noses of Old and New World monkeys are dissimilar. Old and New World monkeys have narrow downward and wide nostrils, respectively.

Speed: Monkeys can run at a fast speed of 34 mph.

Body and Tails: Monkeys have flat faces with flexible, short-chested bodies. Arboreal monkeys have flexible bodies and prehensile tails, which help them climb trees. Diurnal monkeys have strong bodies which allow them to play on the ground.

Limbs: Monkeys have four limbs, including two hands and two feet. Their limbs support their bodies when walking, running, and climbing.

Coat Colouration: Monkeys’ coat coloration varies with age. At birth, infants are orange in color. After some time, they become silver and then black. They are black, silver and brown in different species.

Distribution and Habitat

Monkeys are distributed among continents and savannas. They are diurnal or arboreals from Asia and Africa to Central America and from South America to the savannas of Africa. Across Asia, members of Old World monkeys rest in Afghanistan and the islands of the Philippines, Timor, and Bacon. The Aotidae family spend their lives in Panama and Argentina.

Japanese monkeys spend their lives in the snowy areas of Japan. Monkeys inhabit tropical rainforests. They mostly live in forests where they enjoy themselves in trees. Baboons are diurnals and spend their lives in grounds, grasslands, wooded areas, and rocky sidehills. Some monkeys inhabit warm areas, while some in cold areas.

Diet and Digestion

Monkeys have prehensile tails, which help them when they need food. They collect food like fruits, seeds, leaves and nuts. Monkeys are omnivores. Along with fruits and plant matter, they eat insects, bird’s eggs, small mammals and spiders. Baboons are the largest monkeys that can eat rabbits, antelopes, and guinea fowl.

Monkeys have a complex digestive system with a multi-chambered stomach. Their digestive system is similar to humans because monkeys are mammals. Howler monkeys have a fibrous diet that takes time to digest. The food is going through a process of peristalsis. Monkeys’ stomachs break down enzymes and defecate extra matter from the body through a well-defecated system.

What are Cheek Pouches?

The pockets on both sides of the head, between the jaw and cheek, are called Cheek Pouches. Cheek Pouches are a feature of Old World monkeys. In macaques, mandrills, baboons, and patas monkeys, there are Cheek Pouches, which store food for later chewing.

Behavioral Adaptations

Monkeys adapt to many behaviors. They learn tactics, use vocalizations and perform many actions.

Social Behaviour

Monkeys are socially constructed mammals. They tend to live in troops that comprise one male with young and several females. Males are the leaders of troops. Females can spend their lives in troops where they are born, while males join other troops when mature males move to other troops and make their own families.

Learning Behaviour

Monkeys are clever but genius acrobats. They can learn things hurriedly just by seeing. They move tree by tree and show their skills. Monkey bars for children are designed after their enchanted skills. Stick-using behavior is an excellent technique. Monkeys use sticks to capture food or to probe their nose.

Social Grooming

Monkeys are fascinating creatures. Their bonds are socially strong. One of their unique abilities is maintaining and cleaning their bodies(allogrooming) by using water and picking up lice from each other’s bodies. They clean themselves in swimming pools.

Communication

Monkeys are captivating mammals that use different vocalizations. They use alarm calls that prevent species or individuals of a family from predators. Monkeys produce a Krak sound for a leopard alarm and a Hook for an eagle alarm. They communicate through scent marking and showing facial expressions. Vocalizations of screaming, barking, grunting, moaning, wailing, and hooting are used by New World monkeys.

Reproduction and Parenting

Different species of monkeys reproduce in different seasons. Their gestation period is 4 to 8 months. Studies show that some species reproduce in the rainy and spring seasons, while others in late summer. On average, they are sexually mature 1.5 to 8 years. Females and males become sexually mature at 4 and 5 years, respectively. In marmosets and tamarins, the number of births is 1 to 3.

Old World species give birth to 1 individual, while 2 young are rare. Male and female monkeys both raise their young. Females can nurse their babies, but male also raises their young at 5 months. They carry young on their backs and take them to forests to leap through trees and do some tactics. Babies cling to their mothers because they are helpless when they are infants.

Mortality Rate and Life Span

The infant mortality rate of Macaques is 57%. In monkeys, the highest mortality occurs in the first year of life.
Thirty-three percent of Macaques reach 33%. Monkeys’ mortality can exceed 55%.

The life expectancy of Baboons exceeds 45 years in captivity, while in the wild, they can live up to 25 years.
In comparison, Macaques rhesus spend 26 to 40 years in captivity, while 30 to 36 years in the wild.

Ecological Importance

Monkeys are ecologically crucial animals and are herbivores. Monkeys consume fruits and nuts and defecate seeds, which helps disperse them. They are prominent in the regrowth of forests and fertilize the soil. Monkeys live in most regions of the World, so forests and grasslands are significant for them. They also protect grasses and land by eating insects and small mammals.

Conservation Status and Efforts

There are 200 species of monkeys left in the World. According to the Red List of the International Union for Conservation of Nature, monkey species are critically endangered, least Concerned, and vulnerable. More than 38% of monkey species are endangered and critically endangered. Approximately 22% of species of monkeys are Vulnerable, and 57% are Least Concern.

They are suffering from threats. Their lives are at risk, and they are arrested for eating meat and fur. Monkeys are used in animal research. Private organizations train them and suffer from threats when they are kept for public entertainment. Deforestation is another reason for the loss of habitat. That’s why their species are at a loss. To preserve these animals, there is a need to take decisive action.
