My Deep-sea Fishery

Xiang Yang and Wu Shiwen looked at each other and saw the helplessness in each other's eyes.

This foreigner has been arguing how beautiful this thick-shelled sea cockle is, and tried to get Xiang Yang and others to accept the aesthetics he conveyed, but never mentioned that this thick-shelled cockle is the raw material of Yuanbei. .

Xiang Yang secretly said in his heart that 80% of this foreigner did not know what the domestic sea treasures said.

To be reasonable, this should be a good thing for Xiang Yang and Wu Shiwen, so why is Xiang Yang helpless.

Because Xiang Yang also understands why Gao Chuang kept pulling the Yingwanghai Jumei and not letting go.

Obviously, Gao Chuang had also taken a fancy to these thick-shelled sea cockles, using Yingwanghai cockles as a guise, and he was bargaining vigorously.

Sure enough, after discussing with Gao Chuang to no avail, Gu Lan spread his hands helplessly, "Gao, my friend, this is the lowest price that can be given. If it is lower, I will not even be able to charge the cost. I'm back, but you like good-looking things. I have something here that you should be interested in."

"Oh?"

Gao Chuang pretended to be very interested, "What is it?"

"You wait, I will go to the cabin to take it out for you now." Nagelan said.

After Glenn left, Gao Chuang took off his gloves and lighted himself a cigarette. First he took a nice sip, and then he said boldly, "This foreign devil, he is still tender to fight with me. You will wait for a while. Look, see how I can get these thick-shelled sea cockles cheaply."

Xiang Yang wondered: "Mr. Gao, people also specialize in the production of seas, don't you know the value of sea chrysanthemums?"

"This involves the differences between Chinese and Western cultures." Gao Chuang said with a smile.

"The sea snails are called red snails in the West. They are more expensive than gold, and they are loved by people from all walks of life in the West. There are even many snail lovers who resist killing the red snails. Therefore, in foreign countries, the sea snails are generally used. Not for eating, but for viewing."

"In our East, the sea chrysanthemum is called Yuanbei, one of the eight treasures of the sea."

Xiang Yang heard the words and nodded with a smile, "Speaking of this, there is another very interesting thing."

"It is said that during the Qianlong period, a foreign envoy offered a pair of Yingwanghai chrysanthemum clams to Emperor Qianlong. The Emperor Qianlong didn’t know him and asked the royal chef to cook a dish. After eating, he thought it tasted good, so he followed that. Foreign envoys praised the sea chrysanthemum."

"In fact, the pair of red snails are not for eating at all."

Gao Chuang smiled and shook his head, "It's me, I use it to eat too, such a superb Yuanbei is not used to eat, but to keep it for viewing, it's really a gluttonous thing."

"Okay, don't say anything, that foreign devil is here, don't let him hear this, let's see what he brought here this time."

"Gao, my friend, made you wait a long time. I brought my baby. I believe you will like it this time." Glenn walked over with a smile. Behind him, there were four A tall white man carried a large water tank.

"Oh, then I must take a good look." Gao Chuang smiled and walked towards the water tank.

Xiang Yang also looked curiously into the water tank.

As a result, Xiang Yang showed a disappointed look on his face, "What? Isn't this a sponge?"

Gu Lan was immediately unhappy, and he solemnly said: "Xiang, take a closer look, this is not an ordinary sponge."

Xiang Yang stared at the inside of the water tank carefully for a long time, "Isn't this a very common six-sponge class?"

"Wrong, this is the oldest animal on this planet, and a real living fossil." Gu Lan said with a mysterious face.

"Forehead."

Xiang Yang was almost choked by Glenn's words, especially when Glenn was saying this, his expression on his face was content and mysterious. How did Xiang Yang think it was funny.

That's right.

The sponge is indeed one of the oldest creatures on earth.

But at the same time, sponges are also the simplest creatures on earth.

In the past, humans have gone through a long and complicated cognitive process of the sponge's positioning in biological evolution.

But today, sponges are no longer mysterious to humans.

Sponge is a living fossil, but it is not worthy of commercial praise.

Because sponges as living fossils, apart from providing some evidence for biological evolution research, have no commercial added value at all.

In Xiang Yang's view, the sponge is just a primitive, the lowest, aquatic multicellular animal that can be seen everywhere, and it has no commercial value at all.

Gao Chuang showed a very interested look, "I have seen these things near the equator, can they survive in Antarctica?"

Glenn quickly said: "Yes, don't you look at its structure is very simple, but it is actually a very special biological group, the body contains extremely rich biologically active substances, even if you trample it to pieces, change As a single cell, it can still live, you can think of it as a flower, and every piece of it is a seed."

Xiang Yang smiled slightly and said nothing.

In the past, when sponges were called flowers and fruits, sponges were still a very mysterious creature.

At one time, many people thought that they could not walk and could only drift with the flow, or that the sponges on rocks, shells, aquatic plants or other objects in the water were plants.

However, in modern times, since the appearance of the microscope, all mysteries about sponges have been solved by humans.

Although the sponge looks like a plant, it is actually an animal.

"Brother Yang, is this sponge really a flower?" At this time, Wu Shiwen on the side asked in a low voice.

"of course not."

Xiang Yang shook his head and said, "Although the sponge has no mouth, no digestive cavity, and no nervous system, it is indeed an animal, one of the simplest low-level animals."

Most of the sponges living in seawater are gray-yellow, brown or black lumps.

Many sponges have many bulges on the body surface, and there are many small holes of different sizes around the bulges.

Sponges can use these small holes to let prey **** themselves.

Although the individual sponges vary greatly in size, the small ones are only a few millimeters in size, and the large ones can even reach hundreds of meters, but the internal structure of the sponge is very simple regardless of the size.

The entire body of the sponge consists of two layers of cells inside and outside. There is no differentiated tissue in the body, but some cells are different in structure and function.

It is said that the sponge has a very strong filtering function. A complete sponge has 400 billion small holes on the body surface which are the same as the body cavity, and are supported by sandy fiber bones. It is like a channel system densely covered with thousands of water networks. .

A sponge with a diameter of only one centimeter can filter 20 kilograms of seawater a day. It is a very important part of the entire marine ecosystem, and it is also a very practical seafood in the aquarium.
