Introduction map of the world's largest monkey mandrill and the fiercest colorful mandrill. Colorful mandrill is the largest monkey in the world, with a strong body and a height of more than 70 cm, which is equivalent to a one-year-old or two-year-old child, but it is not a docile monkey. It is very violent and aggressive. An adult certainly doesn't want to face a crazy colored mandrill. It will turn blue, which is also of interest to scientists. Let's uncover the secret of the colorful blue face of mandrill.

The largest monkey mandrill in the world.

Mandrill is the largest primate in the world, with a large and long head, 1 bony processes on both sides of the nasal bone, vertical ridges, grooves between the ridges, and green and bright red skin between the ridges. The male has about six main sulcus on each side, and the red part extends around the nasal bone and snout. This colorful special pattern looks like a ghost, so it is called mandrill.

Mandrill is strong, with a body length of 6 1-76.4 cm and a short tail of 5.2-7.6 cm. The average weight of females is 1 1.5 kg, and that of males is 25 kg. Mandrill has a ghostly face, a long face and a bright red nose, which makes this bright color stand out more than the surrounding dark color. There are deep longitudinal stripes on both sides of the nose, a pinch of goatee under the chin, and the head is hidden in long hair. The hair on the body is brown and fluffy; The ventral surface is yellow and brown, and the hair is long and dense; The back is red, so are the genitals; Hips are purple because they are rich in blood vessels, and the color will be more obvious when you are emotional. This is partly because female mandrills like it, and another reason is that it is easier for them to see the positions of other members when they walk in the dense forest. The facial color of female and underage mandrills is much darker than that of males. Bright colors help mandrills identify and communicate with each other in the dense jungle. The forelimbs are longer and stronger than the hind limbs, so the rear part leans down when exercising.

Why do colorful mandrills turn blue?

Evolutionary biologists at Yale University and mathematicians at the University of Kansas observed the blue skin tissues of animals, including the cheeks of mandrills and some body parts of long-tailed monkeys. It is found that the collagen fibers in the skin are regularly arranged in parallel. As the main extracellular adhesion protein of the skin, collagen can maintain the integrity and elasticity of the skin and affect the color of the skin at the same time. Scientists have found the optical characteristics of these fibers with the same thickness, equal distance and parallel arrangement through calculation. They reflect a single wavelength of blue light, and other reflections cancel each other out, so the skin looks blue. If the distance between fibers increases, the blue color will become lighter. Therefore, the blue color of animal skin comes from the reflection effect formed by the regular arrangement of protein fibers, rather than aimless scattering.

Male mandrill is a unique species in tropical African rainforests. Its face is bright red and blue, which perfectly matches the striking colors of its hind legs and buttocks. The brighter the color of male mandrill's face, tail and vulva, the higher its status. A study in 2005 showed that the bright colors of these parts can sometimes help them avoid conflicts. In addition, female mandrills also prefer males with more gorgeous fur.

What are the life habits of colorful mandrills?

Feeding habits:

Mandrill is an omnivore with a diversified diet. It usually eats plants, and there are more than 100 kinds of plants that it can eat. It likes to eat fruit, but it also eats leaves, vines, bark, stems and fibers. It also eats mushrooms and soil. Most mandrills eat invertebrates, especially ants, beetles, termites, crickets, spiders, snails and scorpions; It also eats eggs, even including vertebrates, turtles, frogs, porcupines, mice and shrews. If given the chance, mandrills may also eat larger vertebrates.

Typical activities:

Mandrills are social animals, with an average of more than 600 animals in each community, up to more than 800 animals. The largest population observed was over 65,438+0,300 mandrills. There is a strict hierarchy, and a male mandrill is a monkey. Head monkeys are usually brightly colored and have huge patterns. Most adult male mandrills live alone in the mountains, and there are also small families. Male leaders lead several female mandrills to live with young mandrills. The mother mandrill and the little mandrill basically move under the tree and don't like climbing. They spend most of their time on the ground and usually only climb trees at night to rest.

In addition to climbing trees when looking for food and avoiding danger, mandrills spend most of their time in open areas of forests. Their running ability is very strong, the fastest can reach 40 kilometers per hour, far exceeding the macaques known for their agility. Sometimes mandrills will gather in large groups to feed in agricultural areas, which will bring huge losses to agriculture and be killed. However, due to the rampant poaching and the decrease of habitat, the survival of mandrill is facing a great threat.

Fight:

Adult mandrills are violent, fierce and aggressive, and can fight with medium-sized beasts. The leading old male monkey is brave and aggressive, with long and sharp teeth, sharp claws and great arm strength, which is about three times that of ordinary adults. It threatens all kinds of enemies. Angry, even the little leopards are in awe of them, and sometimes attack animals such as poisonous snakes. Mandrill's IQ is also quite high, comparable to that of baboons, and it is one of the smartest primates.
