After explaining the rhino’s sleeping behavior, Liu Wei said to Rama: “We can slowly get closer now!”

Rama nodded, he couldn't wait any longer.

The two men walked along the marsh bank to where Cook was sleeping.

The Indian rhinoceros sleeps for a long time every day, and its sleep quality is very high. After bathing, it slathers itself with mud to prevent mosquito bites, and falls asleep as soon as it lies down.

The approach of Liu Wei and Rama did not disturb it, and it slept soundly.

Lama's eyes showed deep care. She squatted next to Cook and stared at the sleeping Cook with a smile.

"Brothers, while the rhino is asleep, let me add some knowledge about the Indian rhinoceros."

Liu Wei moved to Cook's head to take a photo: "The Indian rhinoceros is the largest single-horned rhinoceros in the world. It only has one horn growing on its nose, while subspecies such as the African rhinoceros can grow a horn on its head. Two rhino horns, one long and one short.

Many viewers will be very interested in rhino horns, and I think in your mind, you must think that rhino horns are its weapons?"

"Huh? Isn't it?"

“Don’t all bovines use their horns as weapons?”

Liu Wei smiled and said: "First of all, let me correct a common sense question. The Indian rhinoceros belongs to the Rhinocerosidae family. There are four genera and five species of the Rhinocerosidae family. It is the largest odd-dactyl animal in the world. It has nothing to do with the bovids. It cannot be because of it. If there is a word for cow in its name, it is considered to belong to the bovine family."

"Laughing and crying, I always thought rhinoceros was a member of the bovid family!"

"You have gained a lot of knowledge, remember it quickly and don't embarrass yourself next time!"

"Awkward, I remember, a rhinoceros is not a cow!"

Liu Wei went on to popularize the science: "Let's continue talking about rhino horns. When Indian rhinos fight, rhino horns are not the weapons they use to win. They rely on the strength of their bodies to hit their opponents or use their tusks to bite them. Usually the wounds caused by fights between two rhinos are on the edges of the ears or sides.

Therefore, researchers in the reserve often see rhinos with missing ears, which were bitten off by their opponents during fights.

When fighting against each other, their heads do not collide head-on, but lean together sideways, and their necks wrap around their necks to exert force.

Rhino horns are basically useless in combat.

Many people will intuitively guess that rhino horn is very hard. In fact, this is not the case. Its main component is protein, so it is not too hard and is similar to the hardness of sheep horn.

Through the analysis of the chemical composition of Indian rhino horns using infrared spectrometers, , rich in medicinal amino acids, and the closeness of the amino acid composition to standard protein is 0.74!”

"????"

"I'm crying, anchor, what are you talking about?"

"Can you speak human language?"

“A high school degree means you can understand a little bit!”

"Is there any medical student in the live broadcast room who can come out and translate!"

Liu Wei looked at the rolling barrages and could infer that the viewers watching the live broadcast at this moment were all in a state of confusion.

He smiled and said: "It seems that I can't tell you too professionally. To put it more familiarly, rhinoceros horns have high nutritional value!"

"By the way, you can talk about things that can be summed up in one sentence. Really, hey, the anchor still needs to improve his expressive skills!"

Liu Wei smiled awkwardly and thought: Grandma, you don’t understand and blame me?

He shook his head and sighed secretly. He was looked down upon by others for being too educated. He continued: "It is precisely because of the medicinal value of rhino horns that indirectly caused the conflict between Indian rhinos and humans. Wild Indian rhinos are too big because of their size. The big reason is that in its range of distribution, apart from Asian elephants, its biggest natural enemy is humans.

The primary purpose of humans hunting rhinos is for their horns. Poachers kill rhinos and sell their horns. In Arab countries, rhino horns are used as a symbol of social class. In Yemen and Oman, they are used to make ceremonial dagger handles. People He will brutally cut off the rhino horns with a saw.

This is the main reason for the sharp decline in the number of rhinos in India at the end of the last century!"

The barrage slowed down.

The audience was silent for a moment.

They didn't know what to say. It seemed that the main reason why every living thing on earth went extinct was because of human beings' pursuit of profits.

After hearing this before, the audience would get angry, curse the rampant poachers, and sympathize with endangered animals. Today, the audience in the live broadcast room has some sympathy for humans.

Liu Wei could feel the mood of the audience at this time from the barrage atmosphere in the live broadcast room. He smiled and said: "Brothers, what happened in the past can no longer be undone. Fortunately, countries all over the world are now trying their best to solve the problem. To make up for the serious ecological problems caused in the past, the Cook in front of us is already twenty-five years old, and I think he can also feel the change in human attitudes towards them!"

Although Rama could not understand Chinese, he could feel Liu Wei's love for wild animals from Liu Wei's tone.

He turned his head to look at Liu Wei with the kind eyes he looked at Cook, and smiled, indicating that he felt Liu Wei's attitude.

Liu Wei returned to the topic of popular science and said: "Brothers, apart from the rhino horns, the most interesting thing about the Indian rhinoceros is its mouth!"

Focus on Cook's mouth as he exhales.

The upper lip is obviously longer and more pointed than the lower lip, and protrudes quite a bit.

"The huge body of the Indian rhinoceros determines its food requirements. I have mentioned before that its life is not only sleeping but also eating. This living habit is very similar to our country's national treasure, the giant panda, and the giant panda's food amount is also It is very large, and it can rely on its soft forepaws to grab and crush food to improve eating efficiency and ensure the caloric needs for physical activity.

The Indian rhinoceros, which is several times the size of the giant panda, does not have soft forepaws. It can only rely on its own lips to improve the efficiency of eating. Its upper lip is very flexible and can function as a hand. It can twist its lips to grab a piece of food while eating. The big bundle of grass was swallowed into his mouth with his lower lip chewing.

After Cook wakes up in a while, he should go to eat grass. I will take a close-up photo for everyone to see, which will be more intuitive!" Liu Wei explained carefully.

Cook was sleeping deeply and was not affected by Liu Wei's voice. On the contrary, the heavy snoring sound continued to flow into the live broadcast mobile phone, which made the audience unbearable.

Liu Wei had no choice but to stand up and walk to its back to keep the live broadcast phone slightly away from Cook's mouth and nose.

Liu Wei couldn't help but reach out and touch the armor where the Indian rhinoceros' legs meet its body. The raised bumps on the armor were very tactile. If you touch it with a little force, it would feel like massaging your palms.

"Awesome!" Rama also touched it and said to Liu Wei.

He was familiar with Cook's body. Touching Cook's body brought him not only comfort, but also the replay of a memory that reminded him of the time when he first met Cook.

He was looking forward to it, hoping that Cook would recognize him when he woke up and re-establish a strong friendship.
