My deep sea fishery

Everyone looked at Xiangyang.

Fang Youqun is directly smiling: "Yang Ge, you are a science fiction, how do you have a few meters long? How can I have such a big conch in this world?"

Other crew members have no Fang Friendship, "Heart", but it is also whisper.

Even Chen Qingsheng convulsted in his mouth, obviously did not believe in Xiangyang.

It is no wonder that everyone doesn't believe it.

Everyone in the scene, which is not often seen in the conch?

Because of the regular contact, everyone is familiar with the creature of the conch, so everyone thinks that the conch can not be as big as it is.

Do not.

Not everyone thinks so.

"A few meters long conch ..." One year old researchers whispered a few words, suddenly the face changed, and the face was surprised to see Professor Chen Yu: "Dean Chen, I know a conch, very This conch in accordance with Comrade Xiangyang. "

Chen Yu voice trembled, "happened, I also know a kind of conch, the kind of conch appearance is very similar to Xieyang classmates."

"What kind of conch you think is?" The two are in the same way.

Professor Chen Yu is glaring with the old researcher.

One second.

Two seconds.

Three seconds.

Suddenly, the two were brushing together to pick up a cold.

"Shui, straight shell tache!"

"Really straight shell nautigle?" Professor Chen Yu looked at Xiangyang and excitedly trembled.

"Straight shell Nautilus?" Xiangyang is confused.

The rest of the people also erect the ears.

Nautilus is known.

The parrot scache is called Nautiloidea, the generals of the head foot, the marine mollusk of the parrot.

There are 2 genus, 6 of the Nautilus.

The parrot screw is one of the four famous snails. It is really famous.

People on board almost all know that the parrot snails have curled pearls like a shell, and the shell is most only 26.8 cm, but the adult nautilus generally does not exceed 20 cm, a few meters large Nautilus? I know that it is fake.

In fact, the name of the parrot snail known as everyone is called a big umbilical parius.

The big umbilical is the name of the parrot screw, but the body is not big.

Non-but not big, the great rollover snails are actually the smallest vendial species in the entire nautilus family, usually only 16 cm.

The housing housing consists of many chambers, and the jacket is located in the housing, and there is a diaphragm between each chamber.

There are two pairs of rolls 2, with 63-94 wrists, and there is a bit similar to the eight-claws that carry a shell, but no suction cups, and more tentacles.

In addition to cocktary, all the nautilus eyes are simple.

Some of the nautilus eyes are not even lens.

Most of the Nautilus is thin and light, which is a spiral coil, and the surface of the shell is white or milky white, and the growth line is radiated from the umbilical part of the shell. It is smooth and fine, mostly reddish brown. The entire spiral outer casing is smooth, like a parrot mouth, so the name "Nautilus".

Because of the thin reasons, after a parrot is screwed, few shells can keep playing well, so it is generally very expensive.

The Nautilus is basically a bottom impersonatory animal, usually slowly in the deep water of 100 meters slowly with the wrist. It can also be attached to the rock or coral reef. Most of the scientists believe that the Nautilus cannot be swimming, but there are a lot of diving enthusiasts to take the parrot snails in the sea. Image, they can suspend themselves in the sea, sway, float like hot air balloons.

The Nautilus is a famous nightlight, which usually be more active than the day at night, most of the Nautilus is foraging at night, and the day is resting on the ocean in the bottom of the rock.

It is worth mentioning that from the deep sea of ​​the ocean until thousands of meters, there is a trace of parrot, and the Nautilus can adapt to the pressure of different depths.

All the Nautilus is a meat, the food is mainly small fish, soft animals, and underlying crustles, especially the small crab, is the main food of the Nautilus.

The parrot screw has experienced hundreds of millions of evolution on the earth, but the shape, habit, etc. are small, called "activated fossil" in the ocean, which has high value in studying biological evolution and ancient biology. In the bionic science, it also plays a seat. In 1954, the world's first nuclear submarine "Nautili" developed in the United States is to imitate the Nautilus research.

Most of these knowledge ships are basically known.

The name of the Nautilus, almost everyone is like a thunder.

It is because of the thunder, so when Professor Chen Yu touches their knowledge blind spots, they are particularly paying attention.

"Professor Chen, you said that the nautilus is also a nautilus? Why never heard this Nautilus, I have never heard of such a big snail, the supe doesn't, the field is not." Fang Friendou excited .

"Don't worry. Professor Chen Yu raised his hand to push the gold silk border glasses on the nose. After you sink, you haven't heard of the mackel snail, this marine life is too normal. Because of the rare level of this organism, there is even more than the overlord dragon. "

"The rare level exceeds the tyrants of the Dragon? Overlord Long, I have been extinct. Is this straight shell parrot screw?" Someone asked.

"Extinguish, the extinction is long, before the Overlon dragon, the straight shell parrot snail is extinct, but it has been the overlord on this planet, and one of the oldest batch of overlord on this planet is this. This is this The second hegemony on the planet. "Professor Chen Yu said.

Everyone looked at the professor of Chen Yu, as if heard the heavens.

"Teacher, what you mean, this is a fossil left by ancient creatures?" Asked a middle-aged bald researcher.

Professor Chen Yu nodded, "It can be said that the straight shell of the nautilus is the top predator in the ocean of the ancient agedo, which is still another reason why it is more powerful. In short, it is extinct, but instead Its close relatives, small rolls parrot snails are small, and the rolls of the shell and the tenacious life are survived. "

"I don't agree that the nautilus is because there is a stronger creature in the ocean and extinct, and the staple seassence enters the prosperity period, their body is huge, up to 6-10 meters, with a stroke shell, water spray Go forward, swim quickly, find that the prey will quickly pursue it, and use the tentacle to capture it. Most of the animals will be attached to the straight shell parrot. "A old biologist said.

"I said it is just a kind of guess." Professor Chen Yu smiled: "Because I don't believe it, so I need to study, understand the process of life, provide support for the disaster of human beings, this is not our people Is responsible with the mission? "
