My Deep-sea Fishery

"Master Chen, you stare at him a little bit. In case this kid is lucky and really caught a shark, remember to give him a hand. Don't let him be dragged into the sea by the shark." Xiang Yang and Chen The birthday party joked with Fang Youqun.

Chen Qingsheng grinned, "Don't worry, Captain, if its fishing skills can catch sharks, I'll catch a whale and show it to you soon."

Xiang Yang grinned when he heard this. Of course he knew that Chen Qingsheng was also joking.

It was Fang Youqun. He curled his mouth and looked very unconvinced. He threw the fishing line into the sea and mumbled: "I will catch a shark in a while. Don't envy you."

Xiang Yang smiled and shook his head, too lazy to take care of this kid.

As a result, at this moment, Fang You's group's fishing float suddenly sank to the bottom of the water, and at the same time, the fishing line bundle also quickly turned.

Xiang Yang was startled, thinking that this kid wouldn't really catch a shark.

Xiang Yang hurried to the side of the ship and glanced towards the bottom of the sea.

At first glance, Xiang Yang did not recognize the creature that Fang Youqun had caught.

It looked like an oversized earthworm, gray-red, without eyes, a wide mouth, and a body as long as a snake.

Immediately afterwards, Xiang Yang remembered that in the south of the South Pacific, some seas were extremely deep, completely bottomless, and without any sunlight and temperature, there lived an ancient fish called hagfish.

Hagfish and gill eels are close relatives, commonly known as drill belly fish, with a body like a river eel, with a smooth and soft appearance. The front half of the fish body is cylindrical and the second half is flattened. It looks like a very fat earthworm.

Xiang Yang observed the hagfish carefully and found that it really looked like an earthworm.

Inside its wide mouth, there are no upper and lower jaws. The mouth is just a huge sucker. Inside the sucker, there are sharp **** teeth, like rows of combs, which can scrape the meat from the prey.

When Fang Youqun saw that his bait had just been put down, the float had a reaction, and the reaction was still so intense, he immediately yelled with joy, "Brother Yang, look, look at it, I caught it, I caught a big fish. "

"It's probably a hammerhead shark." Fang Youqun expected.

"It's a big fish, give me the fishing rod." Chen Qingsheng said directly.

Fang Youqun immediately handed the fishing rod to Chen Qingsheng. In terms of fishing techniques, Fang Youqun is far behind Chen Qingsheng. Although this kind of big fish does not know what it is, Fang Youqun already knows in his heart that this fish is his own. It can't be caught, so Chen Qingsheng must be asked to make a shot.

I saw Chen Qingsheng lay down the fishing line skillfully, and soon the hagfish was pulled onto the deck by Chen Qingsheng.

"Fuck, what kind of fish is this ugly." Fang Youqun, who was full of expectation, immediately cursed after seeing the hagfish.

"Be careful, this guy is called hagfish, very dangerous." Chen Qingsheng yelled.

Hagfish is very famous in the biological world.

About 600 million years ago, the mountains on the earth moved violently, and many caves were formed after collisions and fractures.

Hagfish have been living in the dark and deep sea since then.

After 600 million years of evolution, hagfish have fully adapted to an environment without sunlight, green, and competition.

Hagfish have no eyes. Their transparent body is clearly visible even their spine and internal organs. Normally, they live by filtering the microorganisms in the water. When they encounter prey, they can also use a sucker-like mouth to scrape a layer on the prey. Meat down.

Evolution is fair in a certain sense, and what is lost will be compensated in other ways.

Hagfish proves this very well.

After being exercised in the harsh environment, hagfish are not afraid of heat or cold, and can survive in water temperatures ranging from minus 40 degrees to minus 20 degrees. This is a function that all other fish do not have.

What's even more amazing is that in order to read the long lack of food, hagfish has evolved four hearts. It can live well without eating any food for half a year.

In the past, humans have always thought that hagfishes perceive environmental changes mainly relying on their mouth tentacles and facial nerves.

However, after careful research by scientists, it is found that it is not only the tentacles and facial nerves that guide the hagfish to accurately approach the target, but also the supersensory cells that are all over the body and are invisible to the naked eye.

In addition, in addition to the line measurement system of hagfish is more sensitive than ordinary fish, the function of their tiny raised sensory cells is also exerted to the extreme, which can completely replace the visual organs.

The tentacles of hagfish can not only detect very small fluctuations, but also have the taste buds on the tentacles that can distinguish different fish. The hagfish rely on these tentacles to get close to the prey.

At one time, some scientists used underwater camera technology to study the predation process of hagfish in the deep sea.

Scientists discovered that hagfish turned out to be the "natural enemy" of sharks.

Fang Youqun said nonchalantly, "Brother Yang, isn't it just a big earthworm? What's the point of caution?"

"Big earthworm?"

"Huh, do you think sharks are scary?" Xiang Yang asked.

Fang Youqun nodded, "The shark is the king of the sea. It is the most ferocious fish except the killer whale. Of course it is terrifying."

"Sharks are invincible on the bottom of the sea. No matter where they swim, other fish are frightened and fled. But hagfish are the nemesis of sharks. Are you saying that hagfish is terrible?" Xiang Yang said.

"What? This thing is the nemesis of sharks? This is impossible." Fang Youqun exclaimed.

"Don't believe it, this is the truth."

Although hagfish are not as big as a shark, their teeth are not sharp, and their strength is much smaller than that of a shark, hagfish can use their survival skills to get into the shark’s belly.

Hagfish eat a lot of food. If there is sufficient food, hagfish can eat twice as much fish per hour as their own body weight.

Hagfish are like silk. UU reading www.uukanshu.com eats and excretes them all the time. Many sharks are killed by hagfish like this.

Fang Youqun heard what Xiang Yang said, and was a little surprised: "Brother Yang, according to you, isn't this hagfish a parasite?"

"More than just a parasite?"

Xiang Yang shook his head and continued: "In addition to feeding on small crustaceans and a variety of fish, hagfish also attacked all big fish. It is a veritable deep-sea ghost. Biologists call it a fish thieves. "

Humans once found more than 120 hagfish in the body of a snowfish.

Sometimes, some seafood is made into sashimi, and there are hagfish cubs in the sashimi. After those hagfish cubs are eaten by humans, they will parasitize in the human body.

There was once a rich man who liked to eat seafood sashimi very much. As a result, his stomach hurts one day. He thought it was appendicitis. After he was sent to the hospital for examination, the doctor found that he had a hagfish more than half a meter long in his body, which was extremely terrifying.
