Chapter 380 381. White Rhinoceros
The little rhinoceros was a bit introverted. Even though Su Yun was very attractive to it, it still didn't dare to take half a step away from its mother. It could only wait to look at Su Yun with its dark eyes, and the eyes were shining brightly.

With a smile on his face, Su Yun walked over and put his hand on the little rhino's head.

The female rhinoceros glanced at Su Yun, but she didn't show a defensive attitude, so Su Yun rubbed the little rhinoceros more reassuringly.

"Why do you still have a rhinoceros in the camp?" Su Yun asked while holding the little rhinoceros on him.

Linda didn't get close either, because she couldn't get close to each other like Su Yun. A mother rhino with children is not the same species as a mother without children. She has only been here for more than a year, and she has been growing up with rhinos. It takes two professors to get close to them.

"This is a white rhinoceros on the northern plains. The horns of the female rhino are too long, which is a dangerous factor. The two professors who have been growing up with her plan to remove her horns to avoid being harmed by poachers. It was attracted by food, and after its horns were cut off, they were sent back to the rhino herd."

Hearing Linda's words, Su Yun paused, looked at the female rhinoceros, reached out and stroked the other's horn, and said helplessly, "A rhinoceros without a rhinoceros horn is still a rhinoceros, but a rhinoceros with a rhinoceros horn is not safe." Guaranteed."

He patted the 20cm-long rhino horn and said, "Oh, let's just live!"

[Sorrowful, this is a true portrayal of the innocence of a man, but the guilt of his wife! 】

[A rhino is so big?Damn, it's taller than Su Yun! 】

[When a species is favored by capital, its life begins to become dark, just like the former slaves. 】

[White rhinoceros?Isn't the white rhino almost extinct?Can I still see it here?really? 】

Su Yun touched the slightly rough horn of the rhino and said, "The white rhino you mentioned that is about to become extinct is the northern white rhino. The white rhino here is the southern white rhino. It is a subspecies, but not a species."

"In 2018, the last male northern white rhino died at the age of 45, and the only two northern white rhinos still alive are his daughter and granddaughter, both of whom are female and have no chance of reproduction. Therefore, In other words, after the death of these two female northern white rhinos, this species will be completely extinct in the world."

After a pause, Su Yun said, "Perhaps you don't understand how this kind of extinction feels. Just imagine, in the interstellar world, the only surviving human being is raised by aliens and posted on the interstellar video website, saying in alien language that this is the last Does a human being understand this horror?"

"But this situation can no longer be saved by humans. As for cloning, some people say that there are conditions for cloning. Although the dead male northern white rhinoceros left behind sperm, the only two surviving white rhinos are his descendants. , even if fertilization is successful, it can only be inbreeding, and I don’t need to explain the harm of inbreeding to everyone, so we can only delay the extinction of northern rhinos, but cannot make any effective changes."

Glancing at the barrage, Su Yun said again, "I saw someone on the barrage saying that you can try to hybridize with the southern white rhino."

Sighing slightly, Su Yun said, "But the northern white rhino is a pure northern white rhino? They are a subspecies, but not a species. Although there is no reproductive isolation, the hybrid products can only be hybridization."

"You can understand the northern and southern white rhinos as Siberian tigers and South China tigers, which is easier to understand. Then do you think the Siberian tiger can replace the South China tiger? Or can the South China tiger replace the Siberian tiger? No one can replace it. The same goes for northern and southern rhinos."

[You can try to crossbreed with a black rhino to see if you can produce a spotted rhino!I think, in the past, there were only white horses and black horses on the African continent, and they are about to become extinct. Once the two sides combine, they will become zebras.]

[I saw the last male white rhino when I was traveling in Kenya, but I didn't expect it to be the last one! 】

[Gan!I also went to Kenya when I was 17 years old to watch the great migration of animals. I forgot about the white rhino. I missed it! 】

[Hey guys, these are all rich people, I’m so sad]

The bald professors also gathered around the fire and began to fry the food. They were surprised to see Su Yun who approached the rhino so easily.

"It seems that there is a reason why he has gained so many fans around the world. I thought that only Brown and I could get close to Eva. After all, Eva has known us since childhood."

Brown turned the steaks one by one and said, "There is an old saying in Huaguo, if you don't have diamonds, you can't do porcelain work, otherwise you don't have the skills, and dare to go into the wilderness alone?"

Not paying attention to the discussion around the bonfire, Su Yun said, "Since I am lucky enough to meet a white rhinoceros, I will share some popular science with you here. The original name of the white rhinoceros comes from the Dutch word "weit", which means wide and flat, but it was gradually said to be "" white" white, and finally became a white rhinoceros."

"As the second largest animal among terrestrial vertebrates in the world, the white rhino is also the only grass-eating rhino, almost all of which feed on short grass."

"Unlike the tragic fate of the northern white rhino, the fate of the southern white rhino is much better. Their numbers are healthy, which is the only consolation for the imminent extinction of the northern rhino."

Touching the back of the female rhino, Su Yun said, "Whether it is a northern or southern rhino, they are very docile and like to live in groups, but there are only female rhinos and calves in the population, and the male rhinos like to live alone."

After a pause, Su Yundao said, "There is a mistake in language. The northern white rhino can no longer form a cluster."

"Unlike other animals, whether it is the wolverine, Siberian tiger or brown bear we have seen, their territories are larger for males than for females, but the white rhinoceros is different. The territory of the female white rhinoceros is larger than that of the male white rhinoceros. Yes, but the male white rhino remains dominant and allows subdominant males and adult females to roam his territory."

"The white rhino's eyesight is poor, and it mainly relies on hearing and smell. It can run at a maximum speed of 40 kilometers per hour, and its body shape does not match at all. Therefore, even if it does not have the horn in front of it, if it causes the opponent to attack, the speed and body size alone will be enough to kill the white rhino. No animal dares stand in front of it."

Taking a look at the female rhino's lips, Su Yun continued, "Just like humans, the estrus period of white rhinos is not fixed. Males will sing love songs when they are courting, but the sound is a bit strange, and humans cannot appreciate it."

"The female gives birth every three years, and the gestation period is about 547 days, which means that at about 18 months, only one calf is born each time. The newly born rhinoceros will follow the mother's buttocks in the first three days, But after three days, they prefer to run in front of their mother."

"The little rhino in front of us has been hiding next to the mother rhino. It is probably due to the unfamiliar environment and perhaps personality problems."

Taking a long breath, Su Yun said, "The northern white rhino will become extinct sooner or later. This cannot be changed, and don't wait for the real pain to take painkillers. Then, protecting the southern white rhino is the most important thing." It's too heavy."

"I think it's more important than looking at the only northern white rhino."
