My Deep-sea Fishery

Soon, the rested crew members went down to the sea again to continue the collection work.

This time, Xiang Yang also went to help out. He selected some mature and large rock cauliflowers and transported them from the bottom of the sea to the surface of the sea, and then asked the people staying on board to pull the rock cauliflowers up from the bottom of the sea.

Of course, Xiang Yang didn't do this all the time.

After Xiang Yang made two trips and found that the crew, under the leadership of Chen Qingsheng, could do the job very well, and he didn't need him here at all, he immediately stopped taking the initiative to collect those cauliflowers.

After being free, Xiang Yang swam towards the mysterious sea covered with hoarfrost again.

This time, Xiang Yang did not directly go down to the bottom of the sea, but swam to the top of that sea area first, and then lowered his head to look down at that sea area. He wanted to take a good look at the bottom of this sea area.

To be honest, the mysterious hoarfrost covered under this sea area is very wide, and the vast expanse of whiteness on the bottom of the sea is like a world of ice and snow. Looking down from above, it is very spectacular and beautiful, as if people are standing on high In the air, looking down on the winter of Daxinganling.

"These things, shouldn't they be coral polyps?" Xiang Yang wondered from the bottom of his heart.

Whether it is the super-large sea cucumber that Xiang Yang discovered before, or the small sea fish that are shuttling through the whiteness, it proves that these white frosty substances are not poisonous substances, at least for most marine life , it is not a toxic substance.

But Xiang Yang really couldn't figure out what these white things were.

Xiang Yang knew that some coral polyps were white.

However, these white frosty substances do not look like coral polyps.

Besides, these white things are like snow, and it is impossible for coral polyps to live so densely.

Forget it, forget about these white things, look for rare catches.

Xiang Yang started wandering around under the sea.

Although Xiang Yang did not find the second plum-blossom sea cucumber, Xiang Yang found that the species under this sea area are still extremely rich.

A large number of conch snails are hidden under those white frosty substances.

Because the conch itself is also white, it is difficult for ordinary people or marine life to find those hidden conchs.

Xiang Yang only found out after looking carefully.

Moreover, among these conch shells, there are quite a few rare ones.

Even, Xiang Yang saw a living nautilus, the little guy was twisting and twisting in the sea, swimming in the sea like a spinning top.

Maybe when Xiang Yang discovered the nautilus, the nautilus also discovered Xiang Yang.

It suddenly stopped swimming, then sank towards the bottom of the sea at a natural falling speed, landed on the white bottom, and then lay on its stomach, motionless.

Xiang Yang smiled slightly, and swam towards the nautilus.

Although the number of this kind of snail is very rare now, and it is strictly forbidden to catch it in various countries, but Xiang Yang swam over to have a look, so he didn't catch it anyway.

Xiang Yang swam to the side of the nautilus, then squatted down, and carefully looked at this small snail that was not as big as a palm.

After staring at the nautilus for a long time, Xiang Yang found that the appearance of the nautilus was a bit like a chrysanthemum fossil, and it seemed a little different from the normal nautilus shell.

In fact, the nautilus evolved from chrysanthemum fossils.

There were many creatures that no longer exist in prehistoric times. Some prehistoric creatures survived several major disasters on the earth with their strong vitality and survived until now.

But these ancient creatures that have existed until now are actually quite different from their prehistoric ancestors in appearance.

The nautilus is one such ancient creature.

The ancestor of the nautilus is the chrysanthemum fossil.

Xiang Yang once saw a picture of a huge chrysanthemum fossil in a textbook. At that time, Xiang Yang was very surprised. What kind of creature's shell can be so huge that one can almost drill into it.

Chrysanthemum fossils are creatures of the cephalopod class. Literally speaking, their feet grow on the head, just like squid, and they are also shelled molluscs. Ammonites are actually In the history of mankind, it has always been a mysterious creature.

The English scientific name of ammonite is derived from an ancient Egyptian god Amon. The image of Amon created by the Egyptians is a god with sheep horns or sheep's head. The shape of ammonite happens to be very similar to sheep horns.

At that time, many scholars directly referred to ammonite as the horn of God Amon, and believed that ammonite was a kind of holy stone at that time, possessing the magic power to exchange for the future.

In medieval England, ammonites were called serpentines.

At that time, Westerners believed that the ammonite looked like a headless snake, so there was a local legend that the ammonite was a headless snake whose head was cut off by the saint Hilda.

At that time, there were legends that wizards could use ammonites to wake up sleeping gods.

In fact, the main reason why there are so many legends of strange powers and gods in ammonites is that apart from its appearance, human beings have very limited understanding of this kind of creatures, because the origin of ammonites was 400 million years ago. , but became extinct with the dinosaurs about 66 million years ago.

Therefore, chrysanthemum fossils appear in front of human beings in the form of fossils.

In the past, human beings had limited ability to study fossils, so they had so many imaginations. Now scientists know from its fossils that ammonites are a kind of carnivore. They mainly use their tentacles to hunt some fish or animals. Crustaceous creatures.

Some tooth marks are often found on ammonite fossils. Scientists inferred that these tooth marks came from the biggest natural enemy Canglong at that time. At the same time, scholars also found ink on ammonite fossils, so they inferred that ammonites are just like octopuses. Able to evade predators by spitting ink.

Of course, it may also be that many years ago, there was a creature called squid in Chrysanthemum's recipe, and the ink in Chrysanthemum's body was actually food residue.

As far as Xiang Yang knows, female ammonites usually have larger shells than males, which may be convenient for laying eggs. At the same time, there are many types of shells. In addition to our most common spiral shape, ammonites also have this A long strip, a tower, and even this exaggerated irregular shape of the shell.

Moreover, the shell size of ammonites also varies greatly, some shells are less than one centimeter, and some shells grow to more than two meters like giant sea monsters.

Germany has discovered super-giant ammonite fossils with a size of more than two meters in North America.

Xiang Yang was a little puzzled. The more he looked at this snail, the more he felt it looked like a chrysanthemum fossil. Even if the nautilus evolved from a chrysanthemum fossil, Xiang Yang also felt that the appearance of the nautilus must be very different from its prehistoric ancestors. is.
