Most of the nautilus shells on the domestic market are made by Filipino fishermen who retrieve dead nautiluses floating on the sea and dig out the carrion.
Existing nautiluses are mainly distributed in tropical oceans such as the Indian Ocean and Pacific Ocean from the South China Sea to the Philippines and Indonesia. They usually live in relatively deep oceans and like to live in groups.
They live on the seafloor during the day and come out to feed at night. Their main food is plankton and algae.
They have a pair of well-developed large eyes and 88 tentacles. There are 20-30 "air chambers" in the inner cavity of the Nautilus shell.
When the Nautilus wants to sink, it will fill the air chamber with water. On the contrary, if it wants to rise, it will inflate the air chamber. The Nautilus has a record of diving to 600 meters underwater, so look for the best Nautilus underwater.
, is not that easy.
I have made all preparations, but this time, the deepest dive will not exceed 100 meters, which is regarded as adaptive training.
Seeing Chen Qing and the others playing diving happily, Han Peacock did not stop them. Since they liked it, let them do this kind of optional exercise. If there was danger, Han Peacock would help.
At a depth of one hundred meters, there is no difficulty for Chen Qing and others. After all, they are wearing a full set of protective clothing.
Han Peacock did not follow Chen Qing and the others to play in the water a hundred meters deep, but slowly crossed a canyon and continued deep into the seabed.
Those who don’t know the Nautilus don’t know the magic of the Nautilus. Through the Chinese Sinian Corner Stone, the Nautilus tells the world a beautiful story. In ancient times, the Three Gorges of the Yangtze River used to be deep water.
However, through Nautilus, it also provided support for the theory of cosmic explosion, which proved that during the Ordovician period, the moon may have only taken 9 days to orbit the earth.
In 1978, American scientists Kamm and Predy boldly hypothesized from their observations of nautilus shells and fossils that the distance between the moon and the earth was not fixed, but getting further and further away.
Two scientists discovered that the corrugated growth lines on the nautilus shell have the special function of tree rings recording history.
They first observed 40 air cells in nine modern nautilus shells and found that the number of growth lines in each air cell was about 30, which coincided with the number of days in a modern synodic period of 29 and a half days.
This means that the modern nautilus grows once a day, which can be called a "solar line".
Then, they observed 36 cases of ancient nautilus fossils from different geological ages. The results showed that the longer the geological age, the fewer the number of growth lines, but the number of growth lines in the same generation is the same.
On this basis, the two scientists used their unique discoveries in biology to explain difficult problems in cosmology. They believed that in the Ordovician period, the moon orbited the earth in only 9 days, while in the Carboniferous period it took 15 days.
In the Jurassic it took 18 days and so on.
Han Peacock was naturally very interested in such a magical creature, so he couldn't wait to find some nautiluses and raise them in the chaotic space.
Thinking of a large group of nautiluses living freely in a chaotic space, Han Peacock smiled like a fool.
"The snail, the nautilus, the crown snail, and the fourth one is the Wanbao snail. These four famous snails must be well-deserved." While walking on the beach at the bottom of the sea, Han Peacock wondered where to look for the other three kinds of conches.
traces.
Crown snail, also known as Tang crown snail, ranks third and is one of the four famous snails in the world. Because its shape resembles the helmet of a warrior in the Tang Dynasty in my country, it is called Tang crown snail.
It is a rare large conch in the ocean world. The shell is large and thick, with a unique and beautiful shape. The length and height can reach 30 centimeters.
The color of the shell ranges from off-white to golden yellow, with a metallic luster, and the inside and outside of the shell lip show an orange-yellow shield. It is a treasure for home display and play.
Mainly distributed in the Indian Ocean and Pacific Ocean, its habitat is the coral sand bottom. The snail has a beautiful shape and is very suitable for home decoration.
Wanbao snail is the fourth of the four famous snails. It is a large shellfish. Its habitat is near coral reefs. Its general size is 15 cm.
Wanbao snails can not only be used as an ornamental collection, but can also be placed in the palm of the hand for massage and health care. The overall color is golden, extremely noble, the hand feels smooth and moist, and the number is rare and difficult to catch. It has first-class collection, ornamental and decorative value.
According to folklore, collectors can attract wealth and treasures. The placement of Wanbao snails also pays attention to the direction. The lips facing the door means welcoming noble people and bringing treasures.
Wanbao snails have a wide range of origins, and are mostly found around coral reefs in tropical areas of the Pacific and Indian Oceans. They make a living by preying on tiny seaweeds and other marine plants and marine plankton.
Most of China's Wanbao snails are produced in the northeastern waters of Hainan Island.
"When you have time, go to the South China Sea. Although it is a mess every day, there are still many species."
There are many good things in the South China Sea and the Indian Ocean, which gave Han Peacock the idea of going there again.
However, it is too far away to think about that now, after all, he has not even found a nautilus.
As he continued to go deeper into the seabed, Han Peacock felt that the light was getting darker and darker. He took out a strong flashlight from the chaotic space and shined it freely underwater.
As he refined the chaotic space, Han Kongque felt that his abilities were getting stronger and stronger. Originally, he only had the magical power to control water. Now, he not only controls water, but also controls metal, wood, earth, and fire. It can be said that Yin, Yang, and the Five Elements are all
Within his control.
While paying attention to the various creatures on the seabed, Han Peacock walked toward the deep sea. He walked for an unknown amount of time. He looked at the seawater in the distance and opened his mouth wide.
"What is that?" Looking at a huge "black chimney" in the distance, Han Peacock was very surprised.
"Is there a volcanic crater over there?" Han Peacock knew that only places with very high temperatures can heat seawater and cause hydrothermal fluid to spurt out, forming this kind of "black chimney."
"I wonder if there are any special minerals here. If there are, they are very easy to collect!" Han Peacock approached the "black chimney" happily.
In recent years, deep-sea mineral exploration activities have been mainly concentrated in the territorial waters of several countries such as western Japan, New Zealand and Australia. Recently, this activity has also been carried out in the Peacock Sea area of Korea, so he is no stranger to seabed mining.
However, it was the first time for Han Kongque to see the real "black smokestack" on the seabed, because such underwater wonders do not exist everywhere.
Undersea "black smokestacks" are generally formed near the rupture of two plates on the seafloor.
Due to the high temperature of the oceanic crust, seawater heats up in the deep part of the crust. After dissolving various metal elements in the surrounding rocks, it convects up along the cracks and erupts on the seafloor.
Due to the difference in composition and temperature between the mineral liquid and seawater, dense black smoke is formed. After cooling, sulfide particles accumulate on the seabed and its shallow channels, commonly known as "black smokestacks."
The goal of some mining companies is to accumulate sulfide particles on the seabed and its shallow channels after the dense black smoke cools.
"If there is an eruption, there will be convection. If an undercurrent can be formed on the sea floor, it will bring countless microorganisms. With the higher temperature, some tropical marine life can survive around it. Could it be that nautiluses grow nearby?"
Han Peacock knows that most nautiluses now live in tropical seas, and there is now a living environment for nautiluses here.
"Go over and take a look. Even if you can't find a nautilus, you might be able to find some gold and silver ore."
Han Peacock immediately sped up. The minerals on the seabed are too rich. Therefore, even if seabed mining may destroy the living environment of seabed organisms, there are still many people engaged in deep-sea mining.
Regarding deep-sea mining, the debate between mining companies and opponents has never stopped for decades, but it has long been limited to the academic level.
This is because from an economic perspective, it is not feasible to mine minerals on the seabed with a depth of more than 1,000 meters.
Exploiting seabed massive sulfide deposits is a new field for mining companies. This requires not only the development experience and recovery system of oil and gas companies, but also the use of coastal sand ore and other mining technology and experience.
Due to the huge difficulty, there are not many companies with leading technologies in this field. As Han Kongque knows, Canada's Nautilus Company is undoubtedly the leader among them.
With the continuous advancement of technology, Nautilus and other mining companies have begun to try to take steps towards deep-sea exploration. After all, the temptation of resources from the deep sea is irresistible, and this also means that the long-standing debate has intensified.
In some places, the seafloor contains large amounts of manganese nodules that are hard and slowly precipitate in the seawater, becoming rich in iron, manganese, nickel and other metals, making it relatively easy for mining machines to dig.
In other areas, mineral-rich water surges from hydrothermal vents on the seafloor, creating rich outcrops.
Although mining in the vent is extremely difficult, the rewards are also more generous and attractive.
Because the sediment is rich in precious metals and rare earth elements needed to make computers, mobile phones and other modern technology products.
There is obviously a submarine vent here. Mining in such a place is difficult, but it also means greater harvest.
"It's a pity that this place is occupied by Americans. Otherwise, I really hope to mine here. Even if there are no gold and silver mines, it would be great to have rare earth ores and iron, manganese, nickel and other metals dissolved by sea water."
The closer you get, the more you can feel the rich minerals erupted from the seabed vents here.
After controlling the sea water and sending himself in front of the "black smoker", Han Peacock hid in a trench. The resistance of the sea water that continued to move forward was too great, and the temperature was also rising, so Han Peacock did not want to continue to get closer.
Anyway, there is no benefit in getting too close, because even if there are rich minerals in the uncooled sea water, he cannot collect them.
On the contrary, there may be mineral deposits erupted in this trench, or there may simply be nautiluses. (To be continued.)
