When Xiang Yang heard this, he immediately knew that neither Zhang Qicheng nor Li Chao cared much about the sunfish.
He immediately stopped dwelling on the sunfish and brought the topic back to the vampire squid.
Xiang Yang asked: "Mr. Zhang, do you like to raise small luminous fish like vampire squids?"
"That's not the case." Zhang Qicheng shook his head and said, "I went out this time mainly because I wanted to bring back some local specialties, so I bought some strange and exotic seafood."
"By the way, I also brought back a treasure. I'll take it out and show it to you."
Zhang Qicheng stood up, walked to the huge desk, opened a drawer, and took out a wooden box.
He held the wooden box and walked to Xiang Yang with a smile, "Let me show you this. If you hadn't come, I wouldn't have dared to show this to Lao Li."
Li Chao laughed, "What a rubbish! You dare not show it to me? Are you afraid that I will snatch it away?"
Zhang Qicheng ignored Li Chao and opened the wooden box.
Inside the wooden box lay a very strange conch.
Li Chao stood up suddenly.
Xiang Yang also narrowed his eyes.
That strange conch is the Nautilus, which now only exists in the Indian Ocean and the Pacific Ocean.
The Nautilus is a very ancient mollusk that has an evolutionary history of hundreds of millions of years on this planet of life.
Among existing cephalopods, only the nautilus has a shell on its back, and the shell is inseparable from the body.
The nautilus' shell is the miracle of its life, and it also brings endless scientific imagination to human scientists.
When it comes to cephalopods, many people may say they don't know much about them.
In fact, cephalopods are one of the large categories of mollusks. Other cephalopods include squid, octopus, etc. The nautilus is definitely the most special species in this category. Some scientists even boldly speculated that the nautilus is not a native creature on Earth at all, but was brought to Earth by alien civilizations.
The nautilus shell is thin and light, spirally rolled, and the surface of the shell is milky white.
There are growth lines on the shell, which are generally reddish-brown, smooth and dense.
The entire nautilus shell is shaped like a smooth disc and resembles a parrot's beak. It is extremely gorgeous in shape and has great ornamental and artistic value. It is a well-deserved work of art.
Most organisms have undergone billions of years of evolution over the centuries. In order to survive better, they generally follow the natural law of "survival of the fittest" and change some of their body structures as the environment changes.
Like giraffes, as generations pass, their necks will become longer and longer.
Another example is the vampire squid.
The ancient vampire squid fossil was one meter long, almost three times the size of the current vampire squid.
Ancient vampire squids lived in shallow oceans and in the same era as plesiosaurs.
The plesiosaurs at that time were more than ten meters long, swift and extremely ferocious. Vampire squids without hard shell protection could easily become food for the plesiosaurs. Faced with the pursuit of plesiosaurs, the ancient vampire squids had to flee to deeper seas.
As vampire squids migrate to the deep sea from generation to generation, they continue to adapt to the ocean pressure in deeper waters.
During this evolution process, not only did the vampire squid become smaller and smaller in appearance, but its internal structure also underwent earth-shaking changes. They evolved a pigment that allows their blood to store five times more oxygen than other squids. Therefore, the oxygen-deficient environment one thousand meters below the deep sea can become their paradise, and they can still be found even in a 4,000-meter-deep trench.
This is the natural law of survival of the fittest.
But the Nautilus did not follow this rule.
After 450 million years, the habits and appearance of the Nautilus have hardly changed.
There are many people who do not obey Newton's law of universal gravitation.
The only species that does not follow Darwin's theory of biological evolution is the Nautilus.
This phenomenon even puzzles scientists.
When Jules Verne, the father of science fiction, was writing "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 actually 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 nautilus shells are extremely rare.
Because after the nautilus dies, the shell and the animal body will separate. The animal body will sink to the bottom of the sea and rot, while the outer shell will drift on the sea forever. After countless days and nights, one day it will be smashed to pieces by the waves.
"I'll give you one million, this one..."
"Even if you offer five million, this Nautilus will never be transferred to you." Before Li Chao finished speaking, Zhang Qicheng interrupted him without hesitation.
Xiang Yang was amazed when he heard this.
Are you selling nugget gold
The buyer's starting price is one million.
The seller had no intention of selling at all, and was not even willing to pretend to ask for a sky-high price.
Zhang Qicheng closed the wooden box with great care, "I want to treat this Nautilus as a family heirloom. No one is allowed to covet it."
Li Chao quickly stopped him, saying, "Why are you closing it? We don't want to take it. Let us take another look at it."
"Brother Chao." Xiang Yang asked with a smile, "Do you like shells so much? You were like that the last time you saw the conch."
Li Chao glanced at Xiang Yang and said, "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 it in the sea, I will help you fish it out."
Li Chao almost laughed out of anger at Xiang Yang's words, "What do you think a nautilus is? Can you just catch it if you want to?"
Zhang Qicheng also laughed. "The main reason why the four famous conches are known as the four famous conches is because they are extremely rare. Ordinary sailors may not be able to catch a famous conch even if they drift on the sea for a lifetime. I know you caught a few phoenix orchids some time ago, but don't think that it will be easy to catch the four famous conches. You basically won't be able to catch a nautilus in your lifetime."
Xiang Yang raised his eyebrows. He had a nautilus hidden in the Qinglong Bend.
It is also the ancestor of the Nautilus, the straight-shelled Nautilus.
Li Chao also smiled and said, "Forget about the Nautilus. It's impossible to catch any of the four famous conchs again. I appreciate your kindness, but in all these years I have never seen anyone catch the four famous conchs from the sea twice in a row. But the probability of catching one is the same as winning the lottery. How could someone win the lottery twice in a row?"
Xiang Yang was silent for a moment, then took something out from his arms, "This, I just fished it out this morning."
