Chapter 241 240. Close relatives of crocodiles

Su Yun was startled, and the bloody mouth in his sight quickly drew closer, but Su Yun was no longer a fledgling coward, he already had experience in surviving sudden attacks.

With the toes as the center of the circle, Su Yun propped up the ground with one hand, the strength in his waist and abdomen twisted violently, and the whole person rolled out in the air, narrowly dodging the opponent's bite.

What is the habit of the crocodile? Su Yun couldn't understand it in his heart, that is, there is a target prey, and it is a continuous attack.

But how could Su Yun give the other party a chance?Finding the right time, he punched the opponent's nose firmly and firmly, and then saw the crocodile, which was still aggressive and wanted to charge again, suddenly lay on the ground as if its limbs were exhausted, and it took a while before it reacted and stood up again.

Su Yun also quickly retreated to a safe distance, looked provocatively at the crocodile standing up again and said, "Come over again and try, it's not about the nose anymore, I'll just pick out the eyeballs for you."

As he spoke, he scolded, "Get out!"

As if frightened by Su Yun's sharp shout, the crocodile turned around in a panic and dived into the water, disappearing under the water plants.

[This is domineering and domineering! 】

[Can this crocodile recover?Why do they always pop out suddenly and startle people?I dropped my phone again! 】

[Let the anchor pretend again. In ancient times, Zhang Fei shouted back Cao Cao, and now Su Yun shouted back the crocodile! 】

【Is it just me who noticed that the tarantula was trampled to death by Su Yun? 】

Su Yun looked at the affinity that disappeared from his field of vision, and awkwardly picked up the tarantula that had been flattened on the ground and said, "I didn't do it on purpose, I just wanted to let it go, but there was a crocodile attacking me, I was in a hurry Under the circumstances, I can only dodge."

As he said that, he glanced at the tarantula's battered body with pity and said, "If you want to blame it, just blame the crocodile. It has nothing to do with me."

After finishing speaking, he casually threw the body of the tarantula into the water. This is meat, and it would be better to bury the fish in the water than to bury it in the soil.

Looking at the kangaroo corpse with bloodshot eyes not far away, Su Yun rode on the back of the crocodile again and said, "It is indeed easier to popularize science at close range than the great white shark. The reason is obvious."

Touching the scales on the back of the crocodile, Su Yun said, "There are 23 species of crocodiles, and the largest of these 23 species is the crocodile. Not only that, the crocodile is also one of the largest reptiles in the world."

"Like other crocodiles, the crocodile is also a member of the dinosaur family. It has continued since its appearance on the earth 2 million years ago, and its appearance has never changed."

Caressing the quiet crocodile, Su Yun asked with a smile, "So do you know what the close relatives of the crocodile are?"

"For example, the closest relatives of humans are orangutans and gibbons. The closest relatives of cats are rabbit cats and lemon cats. So, what are the closest relatives of crocodiles?"

Hearing Su Yun's question, the audience in the live broadcast room discussed and expressed their opinions one after another. Some said lizards, some said turtles, and even more outrageously, some said it was geckos.

Su Yun smiled, and said, "If you guess based on the size of the crocodile, you may not be able to guess it all day, so I just told you the answer."

"Crocodile, or crocodile, what kind of animal is this? It's a cold-blooded reptile that lays eggs, not a fish! Logically speaking, its closest relatives should be snakes, but it just so happens that their closest relatives are birds."

"As for why, let me tell you. Before we introduced the special stomach of the crocodile, we pointed out that people's digestive system is very good, but sometimes, the food is very large, and there is no chewing function, so the crocodile will eat some stones to grind food and achieve a more comfortable eating state."

"Think about it, do the chickens at home and the common sparrows in the wild all have the habit of pecking at pebbles? This is also for the purpose of crushing food for easier digestion and absorption. This is the first point!"

"The second point is scales. The scales of crocodiles can be seen at a glance, but the scales of birds are attached to the feet. This is the second point in common. The third point is that birds and crocodiles The skull structure is similar, and the skull is connected to the spine through a point to achieve the characteristics of flexible use."

"The most critical point is egg production, so, in summary, the close relatives of crocodiles are birds."

[Increased knowledge! 】

[Then why don’t crocodiles have wings? I want to see crocodiles grow wings! 】

[I also want to see it. It is estimated that crocodiles in the Jurassic period had wings. 】

Su Yun rolled his eyes, I still want to see it, it's really nonsense, if the crocodile has wings, will it still make animals in the sea, land and air alive?
Touching the neck of the crocodile, Su Yun said, "The crocodile also has another name, the naked-necked crocodile. Its neck is very smooth and there are no large scales. Only the crocodile has this feature. Other crocodile species have the same neck. There are large scales as a defense, and through this, the identity of the opponent can be quickly judged."

After a pause, Su Yun continued, "It's summer here in Tu'ao, and it happens to be the mating season for crocodiles. If we have the chance, let's watch them up close."

With that said, Su Yun got up and lifted the crocodile's tail, glanced at the anus of the other party, then put down the tail, reached out and pressed the tailbone above the anus, and said, "Teach you how to distinguish male and female crocodiles. What we have in front of you is an adult male crocodile." Alligator, the distinction is very simple, touch the tail vertebrae above the anus, the tail vertebrae above the anus of the male alligator are more than the tail vertebrae above the anus of the female, and the reason for the large number is because the female needs to grow ovaries."

"Of course, this method of identification is difficult for ordinary people. There are other relatively simple methods. If you know that when both parties are of the same age, the larger one is the male. Moreover, when a mating crocodile is found, the upper one It's a male."

[It is difficult for ordinary people!Does the anchor overestimate the concept of ordinary people?Ordinary people dare to get close to crocodiles. 】

[I live well enough to distinguish what the male and female crocodiles are doing, whether the game is not fun or the food is not delicious. 】

[Holy shit, I found out that Su Yun really wants to teach us!Did this kid get bitten by a tarantula and become stupid? 】

A group of psychopaths, Su Yun slandered inwardly, coughed dryly, Su Yun continued, "As territorial animals, male alligators do not allow other males to enter their territory. They practice polygamy, so the one that attacked me just now Salt crocodiles can only be females."

"Suppose you meet a crocodile in the wild. Normal people can't run away at close range. For example, did you react when the crocodile attacked me? No, and even if you reacted, you couldn't run away from the crocodile. , this thing runs a few minutes faster than Bolt.”

"However, there is a saying that is good, it is to dare to face the bleak life, so when you can't run away from it, you can try to fight back. It's good to scare the opponent away. If you can't scare away, at least die with some dignity."

He smiled and said, "It's like the action I punched on the nose of the crocodile just now. Do you think I scare the crocodile away with a loud shout? Actually it's not, it's because the nerves on the crocodile's nose are developed Extremely sharp, as long as it suffers a heavy blow, it can instantly make the crocodile completely weak, which is the best way to scare the crocodile off on land."
