My Deep-sea Fishery

At the beginning, the huge sand anemone didn't pay attention to the small nudibranch, which looked harmless to humans and animals. It waved its poisonous tentacles recklessly, threatening those who approached it. Only nudibranchs.

Xiang Yang, who was watching the video at the time, felt that the nudibranch must have escaped in embarrassment. After all, no matter in terms of body size or attack and defense methods, the sand group sea anemone far surpasses the nudibranch. of marine life.

The two aren't rivals at all.

Unexpectedly, the moment Xiang Yang just had that idea, the nudibranch jumped up, its body drew a parabola in the ocean, and then accurately passed through the tentacles, directly on the rushed into the large mouth of the sand anemone.

Sand colony anemones wave their tentacles contentedly after devouring the nudibranch.

However, only a second or two later, the sand anemone quickly retracted its tentacles and began to struggle desperately.

It turned out that the nudibranch marine creature got into the body of the sand anemone and was devouring the internal organs of the sand anemone bit by bit.

The injured sand anemone writhed frantically, waving and flapping its poisonous tentacles, but it couldn't resist the attack from inside its body at all.

However, the clownfish and anemone shrimp that parasitize on the sea anemone in the sand group are not opponents of nudibranch marine life at all.

The sand colony anemone in the video became motionless after struggling for a while, apparently dead.

It wasn't until the sand group sea anemone lost its life that the nudibranch marine creature got out of the sand group sea anemone's stomach and began to enjoy the food.

The poisonous tentacles of sand anemones are a favorite of nudibranchs.

The sight of them eating is very bloody and terrifying.

They will eat together with the stingers on the venomous tentacles of the sand group sea anemones. After eating, the nudibranchs will twist their bodies, so that the stingers they eat will pierce their bodies full of holes. It's like a person being "pierced by ten thousand arrows".

But even if nudibranchs are riddled with poisonous stingers from sea anemones, they still won't die.

Although their bodies are riddled with holes and scars, they are actually not dangerous at all.

In fact, in order to protect themselves, the nudibranch marine life pierced all the poisonous burrs in the body through the cavity in the body, without causing any harm to itself.

Nudibranch marine organisms can use the internal air pressure of their bodies to firmly absorb those burrs on their backs. When they need it, it is their means of defense against natural enemies. When they don't need it, they can squeeze and deform their bodies to change The pressure will remove all those burrs.

This kind of self-defense method of "resisting the enemy with poison" can be summed up as no guns, no cannons, and the enemy made it for us. It is very rare among animals. Currently, only nudibranch marine organisms are known to have this skill.

Moreover, this skill is also a special skill among nudibranchs, not all nudibranch marine creatures have such skills.

Only those nudibranch marine organisms that like to prey on hydrozoans can do it. They can store most of the nematodes in the body of hydrozoans in the horn process of their backs, but they will not be harmed themselves.

Scientists have discovered through experiments that the secret of nudibranch marine organisms being uninjured is that they have special cells with very large vacuoles in their bodies.

Also, it's worth mentioning that nudibranchs reproduce parthenosexually.

They are hermaphrodites, and each nudibranch is both a father and a mother when it comes to breeding season.

Spring is the breeding season for nudibranchs. Divers often find several or even dozens of nudibranchs connected in series in spring.

This is the adult nudibranch nurturing and protecting the laughing nudibranch.

There are not many hermaphroditic animals. Nudibranch marine organisms have two very complete reproductive systems. They can lay a lot of eggs at a time. Those eggs will stick to long egg cords and attach to nearby rocks or corals. , like roses in full bloom, red, white, yellow, all the colors of life.

Someone once fished an 18-meter-long egg cable in the sea. After statistics, it was found that it was made of 108,000 eggs.

Of course.

Under normal circumstances, less than one-tenth of those 108,000 eggs would hatch.

Because there are so many natural enemies of nudibranch marine organisms, normally only one in a thousand eggs can grow into an adult, and the chance of survival is appallingly low.

Nudibranch marine organisms have not become extinct until now, probably related to their growth cycle, they grow very fast.

A nudibranch hatches from an egg and takes only two to three months to grow into an adult.

Since there are special fish feeds for raising nudibranchs in the market, it is much easier to raise these nudibranchs. Xiang Yang first thanked Li Chao, and then sent two crew members on duty to let them feed the nudibranchs. This sea tank was carried to the top of the cabin, and he planned to put this sea tank in the library as a decoration.

"Brother Xiang, I'm leaving first." Li Chao bid farewell to Xiang Yang: "If you are free during this time, come to my hotel and taste the chef's craftsmanship in my shop. If the ingredients are bluefin tuna."

Naturally, Xiang Yang wouldn't foolishly agree, if Xiang Yang had to pay for things that cost tens of thousands of dollars a catty, he would be reluctant to do so, and if he asked Li Chao to treat him, he would be a bad person, he said politely: "I'm free." The words must come."

He thought to himself, I will go to sea in these two days, so I am sure I will not be free.

Li Chao waved his hand, "Let's go."

"Bon Voyage."

After Li Chao left, Xiang Yang stood on the deck for a while, thinking about the future.

Originally, Xiang Yang wanted to invite the crew to have some supper.

As a result, the crew who went to play in Huhai Town did not come back until after nine o'clock in the evening. Xiang Yang guessed that they must have gone crazy, so before the crew came back, he ate some snacks to satisfy his hunger, and sat on the boat. After taking a shower, I headed home.

The house at home is not decorated, and the living environment is not as good as the room on Xiang Yang's boat, but because his parents are there, Xiang Yang usually lives at home when he comes back.

Xiang Yang is relatively rich now, so he came up with the idea of ​​redecorating the house.

It's just a fine decoration or a simple decoration, Xiang Yang still needs to discuss some specific matters with Xiang's father.

When I got home, Mother Xiang was making a video call with Father Xiang.

Father Xiang went to Longcheng City, and he hasn't come back yet.

Ever since Xiang's father collected the seafood, he spent more and more time going to Longcheng City, often for a day or two.
