Ye Xuan smiled helplessly after hearing what they said.

Teacher Huang and Teacher He were a little embarrassed.

"Why are you so afraid of me? Did you guys do something bad? Didn't you just secretly discuss me here just now?"

Seeing the terrified faces of the few of them, Ye Xuan made a little joke.

"how is this possible!"

Sister Zifeng said quickly after hearing this, how could they discuss bad things about Ye Xuan?

"Grandpa Ye, you must have heard it wrong. All we said were good things about you."

Peng Peng also quickly said that Ye Xuan's status in their hearts is getting higher and higher, how could they discuss bad things about him.

"Okay, let's not talk about this. I just heard you talking about crayfish again. What's the matter? Do you have any doubts about crayfish?"

In fact, Ye Xuan really couldn't understand why there were so many problems in the heads of these juniors.

After all, these problems are very easy to solve for him, and he really doesn't understand where the many problems in their heads come from.

After hearing this, sister Zifeng exchanged glances with Mr. Huang, and then expressed their doubts just now.

"So you're wondering who the hell came up with the idea of ​​eating crayfish first?"

After Ye Xuan heard this, he couldn't laugh or cry, he really had never heard of such a problem.

"Yes, yes, I read in the encyclopedia that crayfish were a kind of pest at the beginning, and they are very harmful to rice."

"But I don't know who came up with it later. Crayfish are edible, which solves a big hazard."

Sister Zifeng blinked and looked at Ye Xuan, hoping that he would answer this doubt for herself.

"Since you want to know so much, let's talk about it."

Ye Xuan shook his head helplessly, these junior questions are mostly good things, but if you don't even know the answer to such a simple question, it's really unreasonable.

"No way, Ye Xuan wants to know who is the first to discover that crayfish can be eaten?"

"The small bench has been set up, just wait and listen to Mr. Ye telling a story."

"It's amazing. The past few days have really opened my eyes. One is more exciting than the other, and one is more curious than the other."

When the netizens in the live broadcast room heard that Ye Xuan was going to talk about crayfish, they frantically tapped on the barrage.

"Grandpa Ye, please tell me quickly, what is going on with this crayfish?"

Sister Zifeng looked at Ye Xuan excitedly, her eyes were shining brightly, and she was looking forward to the answer to this question.

"Why don't you also talk about popular science about crayfish. Although everyone likes to eat crayfish very much now, not many people know what kind of animal it is and why it swims here."

Teacher Huang continued to talk, but unexpectedly, after finishing speaking, Peng Peng raised his hand quickly.

"I know this."

Peng Peng was very proud when he spoke, after all, this was one of the few questions he knew the answer to.

"Then tell me, what are the attributes of this crayfish?"

After listening to Peng Peng's words, Mr. Huang was also very appreciative, and immediately threw a question in the past.

"This question is super simple. Crayfish belongs to the decapod crayfish family. In fact, it has a very special name, but crayfish is the simplest. It is best to remember that she is also called Procambarus clarkii. This name is a little bit It’s a mouthful, so most people don’t know it.”

Chapter 226 About Crayfish

When Peng Peng spoke eloquently, the people around him were taken aback. They really didn't know that Peng Peng could be so powerful.

"You are really hiding something. I didn't expect to know a lot about crayfish. Let's talk about it. How did you get here?"

Teacher Huang patted Peng Peng's shoulder and seemed very satisfied with him.

"In fact, I took a course in college, which was about animals, but I really like crayfish, so I chose crayfish, and I was my research object."

Peng Peng scratched his head in embarrassment. He didn't expect that the courses he took in college could still be useful now.

"Well said, but not clear."

Ye Xuan also nodded rarely, giving Peng Peng affirmation, and then he continued to add.

"In fact, crayfish are freshwater economic shrimps. They don't live in the sea. They live in fresh water, which is our common pond and lake water."

When Ye Xuan talked about the crayfish, he looked a bit like a professor, which brought everyone back to the time when they were listening to the teacher in class in college.

Everyone nodded after hearing this.

"Because of its delicious meat, it is popular with people. Crayfish smell and permanent streams and swamps. They also have temporary habitats, but in streams, they are usually mixed with plants and woody debris. That would break and weaken the embankment."

Ye Xuan continued.

Everyone nodded after hearing this, and it turned out that this is one of the hazards of crayfish.

"Fortunately, now we know that crayfish are edible, and we have killed many of them with one mouth. Otherwise, the damage to the image would be unimaginable. If the embankment is destroyed, it will cause a torrent. "

Teacher Huang also continued to say that human beings can really do anything.

"That's true, and crayfish are extremely adaptable and have a wide range of suitable growth temperatures. As long as the water temperature is between [-] and [-] degrees Celsius, it can grow and develop normally."

Ye Xuan continued to speak with a serious expression on his face.

"So that's the case, isn't it almost like a cockroach?"

Teacher He also nodded. Cockroaches are also one of the pests. Its adaptability is also very strong, and its reproduction ability is particularly strong. It can lay tens of thousands of eggs at a time.

"Almost, but crayfish can't be compared with cockroaches. Crayfish are things with practical value."

Ye Xuan nodded slightly, and continued to educate everyone about crayfish.

"That's about it for a crayfish."

After Ye Xuan finished speaking, everyone's faces suddenly realized.

However, Ye Xuan still didn't mention who was the first to discover that the crayfish could be used.

"But now we only know about the species of crayfish and some knowledge about it. We don't know who first discovered that crayfish can be eaten."

Sister Zifeng tilted her head and continued to ask.
