My Deep-sea Fishery

Xiang Yang circled the iceberg and slowly dived into the water.

This huge iceberg is like a huge flawless piece of jade. It is completely white, without any flaws, and there is a faint light in the transparency. It looks very pure and very beautiful.

After a while, Xiang Yang slowly dived to the bottom of the sea.

"Huh? Is this a murex? And it's alive?" Xiang Yang just went down to the bottom of the sea when he saw a very strange looking conch.

This conch is orange. Under its shell, there is an inverted siphon more than ten centimeters long. There are two rows of bone spurs of different lengths on the straw. These bone spurs are like a comb.

Xiang Yang stretched out his hand and grabbed the murex.

Although the comb-like thorns on the murex can be used by the murex as a sharp weapon to protect itself from being predated by other marine life, but for Xiang Yang, it has no attack effect at all.

This murex, Xiang Yang, couldn't recognize its specific species, but its shape was very graceful. The shell was slightly spherical, and the shell was about half the size of a basketball.

What caught Xiang Yang's attention in particular was that the helix of this murex was very bulging, and it was divided into twelve layers in total. Each layer had seven longitudinal veins, and a row of long spines grew on it. These things, like The patterns are average, making this murex more beautiful.

Xiang Yang couldn't help thinking of the Venus Murex.

Although the Venus murex is not the most collectible among the murexes, it is definitely the most famous among all the murexes.

The reason why the Venus murex is so famous is because Venus is a god in Greek mythology, in charge of love, marriage, and the growth and prosperity of all animals and plants.

Legend has it that the goddess Venus lives in the ocean, rides a car made of shells, and wears long embroidered hair. She is the embodiment of beauty and love. Everything about her, including the items she uses, should be beautiful.

The Venus murex dared to name it after the goddess Venus, so of course its appearance couldn't be any worse.

It is said that when humans saw the Venus murex for the first time, they were highly praised by its discoverers.

Thinking of this, Xiang Yang thought of another very interesting thing.

Anyone who is engaged in construction knows that when building a tall building, the first step is to lay a good foundation first, then build up layer by layer, and finally cap the roof.

In fact, the murex is also a construction worker.

It's just that the building steps of the murex are completely opposite to those of humans.

When the murex is very young, the mantle that protects the body will begin to secrete a building material, calcium carbonate.

It takes about a year for the murex to complete the first step of its own construction, that is, to build the top floor of the building first.

Then, when the flesh of the murex grows a bit and the top layer is not enough, it starts to build the second layer, then the third layer, and the fourth layer, building down layer by layer until the foundation is laid. .

Xiang Yang wanted to see the structure inside the shell of the murex, but the murex was alive, and Xiang Yang was reluctant to kill it.

It is said that the internal structure of the murex shell is very strange, it is a very beautiful spiral shape, and its body can fill every layer in the shell.

In other words, the shell of the murex is not born with it.

Of course, Xiang Yang is just reluctant to kill the murex, it's not that he can't kill the murex, the murex is not protecting animals.

Even, many dry aquaculture companies spend a lot of money every year to hire someone to kill the murex in the farm.

Regardless of the beautiful shell of the murex, it looks harmless to humans and animals.

In fact, for many economically important algae and shellfish, murexes are their important natural enemies.

Qiangqiang gently stroked the shell of the murex, then turned it over.

In the mouth of this bone murex, there is a radula.

There are many rows of saw-like ribbons on the radula of the murex. These ribbons are neatly arranged, soft and curved, and can scrape algae and lick small shellfish.

In addition, the drilling gland on the abdomen of this murex can secrete an acidic mucus with a pH value of 4.1, which can quickly drill through the shells of other shelled marine organisms. Whenever a round hole the size of a grain of rice appears on the shell, They are basically the work of murexes.

Xiang Yang held the murex for a while and thought about it, then took it directly and continued to swim towards other directions on the bottom of the sea.

Soon, Xiang Yang saw another skull crab unique to Antarctica.

A disgusted look immediately appeared on Xiang Yang's face.

These skeleton crabs, which look like a skeleton, are covered with bacteria. They can survive by eating the bacteria on their own body.

It has to be said that there are relatively few biological species in Antarctica.

Xiang Yang scanned the entire vicinity, only to find three creatures: skeleton crabs, murexes, and Antarctic krill.

At this time, it was nearly half an hour since Xiang Yang went into the water, so Xiang Yang had no choice but to turn back and float quickly to the surface of the sea.

After a while, Xiang Yang returned to the deck.

Chen Qingsheng also just came up from the bottom of the water. He looked at the murex in Xiang Yang's hand in surprise, "Boat, you just dived to the bottom of the sea? And you caught a murex?"

When he was underwater before, Chen Qingsheng also tried to dive to the bottom of the sea, but he only dived more than a hundred meters, and he began to feel tight in his chest and feel uncomfortable all over. The distance to the bottom of the sea is at least several hundred meters away. Naturally, Chen Qingsheng chose to give up without hesitation. He didn't think that someone could dive into the water at this depth with just a diving suit.

Xiang Yang looked at the murex in his hand, and said casually: "After all my life, I finally dived to the bottom of the sea, but the pressure on the bottom of the sea is too high, and I can't move around freely. It was a murex, so I grabbed it and brought it up."

Hearing this, Chen Qingsheng exclaimed in amazement: "Captain, you actually dived down? In such a deep water, if it were me, it would be impossible for me to dive so deep even if I risked my life."

"I can't do it now. I need to exercise more. After a while, I'll change the boat to a more advanced diving suit, and I might be able to go down by then."

"Let's not talk about this, by the way, Captain, did you just see that huge iceberg under the water?"

Xiang Yang nodded, "It's such a big piece, how could I not see it?"

As he said that, Xiang Yang himself felt emotional, "The word tip of the iceberg is really appropriate. These huge icebergs seen on the sea may actually not even have a tenth of the total volume of the entire iceberg. .”

"That's right, to be honest, I was shocked when I saw the underwater part of this iceberg just now," Chen Qingsheng said.
