Who are the ten rarest monkey tribes in the world?

1. Night monkey Under normal circumstances, most monkeys are active during the day, except those of the genus Night Monkey. Known as night monkeys and owl monkeys, this monkey has evolved large eyes with strong light-gathering abilities, allowing them to travel through the woods and catch flying insects even in the dark. The most famous night monkey is the Brazilian night monkey. Their calls are high and low, and changeable, causing loud echoes in the dense forest. This complex and varied cry is very unique. Its noisy chirping often disturbs the "neighbors" from sleeping. They are often found in Latin America in Ecuador, Peru, Colombia and Brazil. 2. Capuchin monkey If you are looking for a monkey butler in the market, you might as well take a look at the capuchin monkey. In the early days, the monkeys worked alongside street performers and as jockeys in hunting dog races. Nowadays, they often serve as home assistants for people with disabilities. Among New World monkeys, capuchin monkeys are widely regarded as the most intelligent. Capuchin monkeys, which have tufts of hair on their heads, are able to work with tools for long periods of time. They mainly live in the tropical forests of South America and Central America. They often move in groups in the canopy. They mainly eat wild fruits, insects and bird eggs, and rarely go to the ground. Capuchin monkeys are relatively slow and eccentric. It has a very docile temperament, and the most eye-catching thing is that it has a long tail that can be curled and twisted, and its face always looks infinitely sad. 3. Mandrill The mandrill is the largest monkey in the world. Its face has red and blue ridges and thick olive-colored long hair. Their nose and rump are bright red, and the color of their nose and rump is more vivid when they are excited. They stand up to 3 feet (about 90 centimeters) tall. Although mandrills are huge and colorful, they actually live in seclusion in the tropical rainforests of Central and West African countries such as Cameroon, Gabon, Equatorial Guinea, and Congo. They have huge tusks, but among similar species, exposing huge tusks is a sign of friendship. Mandrills spend most of their lives on land, feeding on fruits, nuts, insects and small lizards. They have small pouches on their faces where they store food. They sleep in trees at night and choose a different tree to roost in every night. 4. Proboscis monkey Proboscis monkey is native to the island of Borneo in Southeast Asia. It is famous for its huge nose and uses it to attract the opposite sex. Its big nose also serves as a whistle when warning of danger. Proboscis monkeys spend most of their time in trees. It is an excellent swimmer. It was found by fishing boats a mile off the coast. Groups of proboscis monkeys have also been photographed walking upright, making them the only monkey species known to use two legs for effective upright walking. In addition to its huge long snout, the monkey is also known for its pot-shaped belly. This led the locals to call this monkey "Dutch monkey" because the Dutch colonists here often had similar big noses and bellies. There are only about 1,000 proboscis monkeys known to exist. 5. Marmoset The marmoset, which is only 6 inches (about 15 centimeters) long, is a dwarf among monkeys. It is the smallest monkey in the world. However, it can jump 16 feet high. It's like a six-foot tall human being able to jump 200 feet. So if you're a comic book publisher looking for a new superhero, Captain Marmoset would be a good choice. However, what really makes the marmoset famous is that it combines the characteristics of 22 species of organisms, a phenomenon called reproductive mosaicism. This phenomenon has not been found in other primate species. 6. Macaques It’s hard to imagine any other species of monkey suffering more abuse than macaques. In 1948, the first monkey astronaut named Albert was launched on a V2 rocket and suffocated to death on the rocket. In the 1950s, psychologist Harry Harlow used macaque monkeys to study the effects of social isolation on them. As a result, these macaques developed severe mental disorders. Today, a large number of macaques are widely used in medical and biological research experiments instead of humans. Most of them experience stress, pain and death. 7. Howler monkeys Howler monkeys are the loudest land animals in the world. Using large vocal cords and a hyoid bone that can hold large amounts of air, howler monkeys can easily emit loud roars that can be heard up to three miles away. When does the howler monkey's roar occur? So far there is no consensus.

One theory is that it roars when it is excited; another theory is that they will hold this deafening "concert" every night; another theory is that it happens when the sun rises. Howler monkeys live in forested areas in eastern Bolivia, southern Brazil and Paraguay, and northern Argentina. 8. Japanese macaques Japanese macaques, also known as snow monkeys, are the northernmost non-human primates in the world. These monkeys are known for their intelligence and are the only animals besides humans and raccoons that know how to clean their food. Generally speaking, the ratio of female Japanese macaques to male monkeys is about 3:1. Japanese macaques spend a lot of time relaxing in the hot springs of the crater. The monkeys have also been observed snowballing, but seemingly just for fun. 9. Spider-Ape Needless to say, if Spider-Man were a monkey, he would be a Spider-Monkey. Spider apes live in tropical forests in Central and South America 80 to 100 feet above the ground. This monkey has a long curly tail with a tactile pad at the end. Spider-apes with slender arms and legs are very flexible and can spin, swoop, and jump freely in the air. The genus Aranepithecus contains seven species, six of which are endangered and one is probably extinct. 10. Emperor's tamarin The Emperor's tamarin, a primate, got its name because its beard resembles the German monarch Wilhelm II. Although the name came from a joke, it became the official name. Emperor tamarins live in the southwestern Amazon Basin and are distributed in Peru, Bolivia and other countries. Adult emperor tamarins are 24 to 26 centimeters long and weigh about 300 to 400 grams. Emperor tamarins are nimble and can jump from tree to tree all day long. The ten most rare monkeys in the world /Efs/20111117/83613.html
