Chapter 1613: Mandrill

Chapter 1801 Mandrill
The old man with white beard who was squatting on the rock just now suddenly looked up at Zhao Zhongyao and Feifei. It didn't run away immediately, but stared at the two strange humanoid animals, Zhao Zhongyao and Feifei. It feels too strange for these two humanoid animals.
When Zhao Zhongyao and Feifei came to this rock, they could clearly see the true appearance of this old white beard.
This old man with white beard turned out to be a strange monkey. It's just that its cheeks are white. The hair on the whole body is black. In this way, when it sits on a rock, if you don't come to look at it, it feels like an old man with a white beard sitting on the rock.
‘Dad, what kind of animal is this? It should also be a monkey! Feifei said, looking at the little animal on the rock.
‘Of course, this is also a monkey, and we have entered a monkey kingdom. Zhao Zhongyao looked at Feifei and said.
After hearing what my dad said, Feifei joked, ‘dad, then let’s wait a while, will we see Monkey King, the grandson monkey! ’
After hearing what his son said, Zhao Zhongyao smiled and said, ‘Of course it is possible. Monkey King is a six-eared macaque. In fact, it is a macaque. The macaque is not a particularly magical species. Since this underground forest is a monkey kingdom, then we should be able to see some macaques. ’
After hearing what his father said, Feifei smiled again and said, ‘haha, if there are such macaques, we can really see what Monkey King looks like. ’
At this time, Zhao Zhongyao looked at Feifei and said, ‘Don’t worry about what monkey Monkey is, you should see what monkey the monkey in front of us is! ’
Feifei looked at the strange monkey in front of him, and felt a little strange. He didn't know what monkey it was. So he looked at Zhao Zhongyao and asked, ‘Dad, what kind of monkey is this? It doesn’t seem to be afraid of us at all! ’
‘This is called the White-cheeked Gibbon. Zhao Zhongyao looked at Feifei and said.
'what! White-cheeked gibbon. What are the characteristics of this kind of monkey! I want to know something about this white-cheeked gibbon. Feifei looked at Zhao Zhongyao again and said.
‘Okay, let me tell you something about this white-cheeked gibbon! After finishing speaking, Zhao Zhongyao thought about it for a moment, and then told Feifei some knowledge about the white-cheeked gibbon.
White-cheeked gibbon. The body length is 45-62 cm and the weight is 5-7 kg. The legs are short, the palms are longer than the soles of the feet, and the knuckles are longer; the body is slender, with shoulder widths and narrow buttocks; it has long canine teeth. The body hair is long and rough. The male animal is mainly black, mixed with inconspicuous silver, except that there is a piece of white or yellow hair on both sides of the cheek from the corner of the mouth to the upper part of the ear. The body hair of the female animal is orange to milky white, and the abdomen is not black. The hair is distinguished from the black-crowned gibbon.
Inhabits tropical rain forests and subtropical monsoon forests, arboreal. Activities during the day. She is good at using her arms to swing alternately, her fingers bend into hooks, and she gently grasps the branches to throw her body out and move forward in the air. It is an endemic species at the border of China, Laos, and Vietnam. The total number of this species is estimated to be less than 350, and it has become a highly endangered species.
In addition, its canine teeth, molars and other bones are also different from the black gibbon. The canine teeth are longer and have a sharp knife shape. The premolars have double tips. The first lower molar is fan-shaped. The upper molars are covered with 4 tips and the lower molars. There are 5 tips on the top. There is a trapezoidal auburn patch on the top of the head. The male animal has a raised crest while the female has no crest hair. The white-cheeked gibbon has a more slender body and longer limbs. The male is black with a large white spot on each cheek, and the tufted crest at the top is more pointed, long and obvious. The female dark brown crown spots are polygonal. The body is mostly stained yellow, and the chest and abdomen are sparsely dark brown.
The white-cheeked gibbon is a strictly arboreal animal, and its habitat is usually no more than 900 meters above sea level.
During the dry season, activities usually start at 06:30 in the morning and the morning sounds begin. The foraging peak is between 07:00-08:00; the second peak is between 11:00-12:00; the third peak is between 14:00-15:00. Foraging, exercising, playing, and resting are all group activities. The distance between individuals when foraging does not exceed 70 meters.
Usually one hand grabs and hangs on a branch, the other hand picks food, and the two hands alternate. Foraging mostly in the middle and upper part of the tall tree canopy, the height is about 10-25 meters, and it starts to cry every morning, and does not cry when foraging. It takes a variety of tropical wild fruits (berries, stone fruits, nuts, especially like banyan fruit), tender leaves, flower buds, tree buds, etc. as the main food, and also eats insects, birds and bird eggs. There are about 85 kinds of food, among which, plant foods account for 90.6% of the total food. Camp lives in small groups, generally 3-5 per group, a few can reach 7-8.
After Zhao Zhongyao told Feifei about this knowledge about the white-cheeked gibbon, he had some understanding of this kind of monkey.
At this moment, Feifei looked at his father again and said, ‘Dad, so to speak, this monkey is a white-cheeked gibbon. ’
‘Yes, this is a white-cheeked gibbon. It's just that this is a white-cheeked gibbon on Mars, not on Earth. Zhao Zhongyao said again.
After hearing what my father said, Feifei said again, ‘what is the difference between these two gibbons. Feifei said again.
‘The difference is that the gibbons on Mars are bigger than those on Earth. Said Zhao Zhongyao.
‘Then will it attack us. Feifei said again.
‘It should not be. This is also a kind of monkey with a milder temperament. Said Zhao Zhongyao.
‘Then let’s go ahead! Feifei said again.
‘Okay, let’s keep going! Zhao Zhongyao said again.
So Zhao Zhongyao and Feifei walked forward again. Soon, they reached a relatively open area. The trees in this place are not very tall. But there are some huge rocks between the trees.
After arriving at this place, they felt that this place was a little special, different from other places in the forest.
At this moment, Feifei suddenly saw a humanoid animal squatting on a rock with colorful hair on its face, which made people feel like seeing a ghost.
When Feifei saw it, he was taken aback. He looked at the thing and said to Zhao Zhongyao next to him, ‘Dad, see what it is and is it a ghost. ’
After hearing Feifei's words, Zhao Zhongyao stared at the animal. He knew what animal it was right away. So he looked at Feifei and smiled, ‘that’s not a ghost, that’s a ghost-faced baboon. ’
‘What, ghost face baboon. When Feifei heard what his father said, he looked at the animal in surprise and said.
‘Yes, this should be a ghost-faced baboon. So, it looks a little scary. Said Zhao Zhongyao.
‘Then what is a ghost face baboon. Feifei wants to learn more about this ghost-faced baboon.
At this time, Zhao Zhongyao said, ‘this is a kind of baboon in the baboon family. Because of its strange appearance, it is also called the ghost face baboon. ’
‘Dad, does that person understand this kind of baboon! Can you tell me about this kind of baboon? Feifei said again.
‘I know a little bit, I will tell you about this kind of ghost-faced baboon now! Zhao Zhongyao looked at Feifei and said.
Next, Zhao Zhongyao talked about some knowledge about this ghost-faced baboon.
The ghost-faced baboon is actually a mandrill.
Mandrill, the largest monkey primate in the world. The head is large and long, with a bony protrusion on each side of the nasal bone, on which there are longitudinally arranged ridges with grooves in between, green skin on the outside, and bright red between the ridges. Males have about 6 main grooves on each side, the red part of which extends around the nasal bone and snout. This brightly colored special pattern resembles a ghost, so it is called a mandrill.
Mandrills live in small communities and play in the jungle and rocks. The main natural enemy is leopards, but leopards generally hunt only female mandrills and juvenile mandrills.
Mandrill is stout, with a body length of 61-76.4 cm, a stubby tail and a length of 5.2-7.6 cm. The average female weight is 11.5 kg and the average male weight is 25 kg.
Mandrill has a ghostly face, a long face, and a bright red nose, which makes this bright color more prominent than the dark colors around it. There are deep vertical stripes on both sides of the nose, a goatee under the chin, and the head is hidden in the long hair. The hair on the body is brown, fluffy and dense; the ventral surface is pale yellowish brown with long and dense hair; the back is red , The are the same.
The buttocks are purple due to the accumulation of a large number of blood vessels. When emotionally, the color will be more obvious. Part of the reason is that female mandrills like it. Another reason is that they are easier to see when they are walking in the dense forest. The location of other members. The facial color of females and juvenile mandrills is relatively darker than that of males.
The bright colors help the mandrills to recognize each other and communicate with each other in the dense jungle. The forelegs are longer and stronger than the hind legs, so the back tilts downward when moving.
Blue is very common in birds, because birds can use blue pigments to appear blue, such as blue peacocks and blue parrots. Mammals lack this similar blue pigment, and mammals have almost no blue color. So how does a mammal like Mandrill show a blue appearance?
An evolutionary biologist at Yale University in the United States and a mathematician at the University of Kansas used electron microscopes to observe the blue skin tissue of animals, including mandrill’s cheeks and certain body parts of vervet monkeys, and found that the skin The collagen fibers are regularly arranged in parallel, and collagen, which is the main extracellular adhesion protein of the skin, can maintain the integrity and elasticity of the skin, and affect the tone of the skin.
. Scientists have found through calculations that the optical properties of these fibers of the same thickness, equal distance, and arranged in parallel, they reflect a single wavelength of blue light, and other reflections cancel each other out, so the skin looks blue. If the distance between the fibers increases, the blue color becomes lighter. Therefore, the blue color of animal skin comes from the reflection effect formed by the regular arrangement of protein fibers, rather than random scattering.
The male mandrill is an endemic species in the equatorial African rainforest. Its face is bright red and blue, which perfectly matches the eye-catching color of its hind legs and buttocks. The brighter the male mandrill’s face, tail, and vulva, the higher its status. A 2005 study showed that the bright colors of these parts can sometimes help them avoid conflict. In addition, female mandrills also prefer males with brighter fur.
Mandrill is a social animal, each community has an average of more than 600, and the number reaches more than 800. The largest population that has been observed exceeds 1,300 mandrills. There is a strict hierarchical system. A male mandrill acts as the "headed monkey". "The head monkeys are usually bright in color with huge patterns. Most adult male mandrills live alone in the forest. Others have a small family. The male leader leads several female mandrills to live with young mandrills. Female mandrills and small mandrills are basically active under trees and do not like to climb. Most of the time they live on the ground, and generally only climb to the tree to rest at night.
In addition to climbing up trees when foraging and avoiding danger, mandrills spend most of their time in the open areas of the woods. They have a strong running ability, reaching 40 kilometers per hour at the fastest, far exceeding the known agility and agility. Macaque. Sometimes mandrills will gather in large groups and go to farming areas for food, causing huge losses to agriculture and being killed. Due to the rampant poaching activities and the reduction of habitats, the survival of mandrills is facing a great threat.
The adult mandrill has a violent personality, fierce and aggressive, and can fight against medium-sized beasts. The leading old male monkey is fierce and aggressive. The teeth are long and sharp, the claws are also sharp, and the arm strength is also quite big, which is about three times that of ordinary adults; All kinds of enemies are threatening. When they got angry, even the small leopards were in awe of them, and sometimes they attacked snakes and other animals. Mandrill is also quite high in IQ, comparable to that of baboons, and is one of the smartest primates.
Zhao Zhongyao looked at Feifei, and told him the knowledge about Mandrill. After Feifei heard what his father said about mandrills, he knew that mandrills are a very ferocious primate.
So Feifei looked at Zhao Zhongyao again and said, ‘Dad, this animal has a fierce temperament, then can’t we provoke it? ’
After hearing what his son said, Zhao Zhongyao smiled and said, ‘Of course, this animal is no better than the little monkeys we saw before. This animal is tall and is the largest primate. Let's not bother it. ’
After hearing what Zhao Zhongyao said, Feifei said again, ‘then where should we go now. Should we walk past this place? ’
'Yes! We must walk past this place. Because only this place is relatively open. There are cliffs on both sides. It will be more troublesome if we want to walk from both sides. Zhao Zhongyao looked at the surrounding terrain, then looked at Feifei and said.
