My Deep-sea Fishery

As soon as Xiang Yang heard it, he immediately knew that neither Zhang Qicheng nor Li Chao cared much about the sunfish.

He immediately stopped worrying about the sunfish and brought the topic back to the vampire squid.

Xiang Yang asked, "Mr. Zhang, do you like raising small glowing fish like vampire squid?"

"That's not true." Zhang Qicheng shook his head and said, "I went out this time, mainly because I also wanted to bring back some local products, so I bought some weird seafood."

"By the way, I brought back a baby, I'll take it out and show you."

Zhang Qicheng got up, went to the huge desk, opened a drawer, and took out a wooden box from it.

Holding the wooden box, he walked up to Xiang Yang with a smile, "I'll show you this, if you don't come, I really dare not show it to Lao Li."

Li Chao chuckled, "What kind of crap, don't you dare to see it, for fear that I will snatch it?"

Zhang Qicheng ignored Li Chao, he opened the wooden box.

Inside the wooden box lay a very strange conch.

Li Chao suddenly got up.

Xiang Yang also squinted his eyes.

That strange conch is the nautilus that only exists in the Indian Ocean and the Pacific Ocean today.

Nautilus is a very ancient mollusc, which has a history of hundreds of millions of years of evolution on this living planet.

Among the extant cephalopods, only the nautilus has shells on its back, and the shells are not separated from the body.

The shell of the nautilus is the miracle of life of the nautilus, and it also brings infinite scientific reverie to human scientists.

When it comes to cephalopods, many people may say they don't know much about it.

In fact, cephalopods are one of the major categories of molluscs. Other cephalopods include squid and octopus. It is not the native organisms on the earth, they were brought to the earth from alien civilizations.

The nautilus shell is thin and light, spiral-shaped, and the surface of the shell is milky white.

There are growth lines on the shell, and the growth lines are generally reddish brown, smooth and dense.

The entire nautilus shell is shaped like a smooth disc, like a parrot's beak.

Most organisms have undergone hundreds of millions of years of evolution with the changes of the century. In order to survive better, they generally follow the natural law of "survival of the fittest" and change some body structures as the environment changes.

Like the giraffe, after generations of reproduction, their necks will become longer and longer.

Another example is the vampire squid.

The fossilized vampire squid from ancient times was one meter long and almost three times the size of today's vampire squid.

Ancient vampire squid lived in shallow seas, and they were in the same era as plesiosaurs.

At that time, the plesiosaur was more than ten meters long, and it moved swiftly and extremely ferociously. The vampire squid without hard shell protection could easily become the food of the plesiosaur. In ancient times, the vampire squid had to escape from the pursuit of the plesiosaur. to deeper seas.

In the process of migrating to the deep sea from generation to generation, the vampire squid is constantly adapting to the sea pressure in the deeper sea.

In the process of this evolution, not only the appearance of the vampire squid has become smaller and smaller, but also the structure of the body has undergone earth-shaking changes. They have evolved a pigment that allows their blood to store more blood than other squid. 5 times the oxygen, so the hypoxic environment in the deep sea below 1,000 meters can become a paradise for them to live in, and they can still be found even in the 4,000-meter-deep trench.

This is the natural law of survival of the fittest.

The Nautilus did not abide by this law.

After 450 million years, the habits and appearance of the nautilus have hardly changed.

There are many guys who don't obey Newton's law of gravity.

The only one that does not follow Darwin's theory of biological evolution is the nautilus.

This phenomenon is puzzling even to scientists.

When Jules Verne, the father of science fiction, created "Twenty Thousand Leagues Under the Sea", the submarine he imagined was called the Nautilus.

Perhaps Jules Verne himself did not expect that more than a hundred years after his death, the United States really built the world's first nuclear submarine based on the shape of the Nautilus, and that nuclear submarine was also called the Nautilus.

It is also worth mentioning that the number of nautilus shells is very rare.

After the nautilus dies, the shell is separated from the animal body, and the animal body sinks to rot in the bottom of the sea, while the shell floats on the sea forever. After countless days and nights, it will be smashed to pieces by the waves one day.

"I offer one million, this one."

"Even if you pay five million, it is impossible for this nautilus to be transferred to you." Zhang Qicheng interrupted without hesitation before Li Chao finished speaking.

Xiang Yang clicked his tongue when he heard that.

Is this selling dog money?

The buyer's asking price starts at one million.

The seller has no intention of selling it at all, and is not even willing to make a show of asking for a sky-high price.

Zhang Qicheng closed the wooden box very preciously, "I want to keep this nautilus as a family heirloom, and no one is allowed to think about it."

Li Chao hastily stopped him and said, "What are you closing it for? We don't have any idea about it, so let us take another look."

"Brother Chao." Xiang Yang asked with a smile: "Do you like shells so much? Last time you saw the snail, it was the same."

Li Chao glanced at Xiang Yang, "You don't understand."

"I don't really understand." Xiang Yang said with a smile: "But if you really like it so much, next time I see you in the sea, I will help you catch it."

Li Chao was almost annoyed by Xiang Yang's words, "What do you think a nautilus is? You can get it if you want it?"

Zhang Qicheng also laughed, "The main reason why the four famous snails can become the four famous snails is because they are extremely rare. An ordinary seaman may not be able to catch a single famous snail after a lifetime at sea. I know You caught a few phoenix orchids a while ago, but don’t think that it’s easy to catch the four famous snails, it’s basically impossible to catch a nautilus in your life.”

Xiang Yang raised his eyebrows, he was hiding a nautilus in Qinglong Bend.

Also the ancestor of the nautilus, the straight-shelled nautilus.

Li Chao also smiled and said: "Let's not talk about nautilus, any of the four famous snails can no longer be caught. I appreciate your kindness, but I have never seen anyone in a row twice in a row for so many years. The four famous snails were caught from the sea, but the odds of catching one are like winning the lottery, how could someone win the lottery twice in a row?"

Xiang Yang was silent for a moment, then took out something from his pocket, "This one, I just caught it this morning."
