My Deep-sea Fishery

Wrasse has a very magical sex change magic.

When not breeding, all wrasses in the entire area are female.

During the breeding period, countless wrasses will gather together, and the oldest female will change into a male wrasse, responsible for protecting the female fish and breeding habitat, while the second oldest female wrasse will will be the ruler of the entire clan.

If the male of a wrasse school dies, the oldest female that dominates the wrasse population becomes a male, taking over the deceased male's position.

It is very amazing that the sex change of wrasse takes only a few hours, and it can fertilize fish eggs in just two or three weeks.

And the degeneration of wrasse is not irreversible.

Females can turn into males, and males can turn back into females.

For example, when two groups of wrasses meet and one of the males cannot beat the other, it will become a female, allowing the leader of the other group to lead the two groups.

Fang Youqun opened his mouth wide after hearing this, "Isn't this fish amazing?"

Chen Qingsheng snorted, "Amazing? That's called miraculous? What's more miraculous is yet to come."

"Ah? There's more?" Fang Youqun was stunned.

Xiang Yang smiled and nodded, "Look at what fish we caught in this net."

"Bass, pike, saury, octopus. There is also a double-faced turtle. The fish in this net are too mixed, and the catch is not many, but the variety of fish is outrageous." Fang Youqun replied.

Xiang Yang smiled, "Let's talk about barracuda and hairtail, these two kinds of fish are very ferocious fish, they both belong to the ranks of marine predators, and they are natural enemies of each other. Normally speaking, it is impossible for them to be in the same sea at the same time. These two kinds of fish appear, because as soon as they appear, they will fight until the other one is eaten. With this net, we not only caught these two kinds of fish at the same time, but also many other kinds of fish. Don’t you think Is it amazing?"

Fang Youqun nodded, and then shook his head again, "Maybe these fish just happened to pass by this sea area. Although it is a bit magical, what does it have to do with whether the wrasse is magical or not?"

"The relationship is getting bigger." Xiang Yang shook his head and said with a smile: "Actually, strictly speaking, the wrasse is an invincible fish."

"Ha, invincible?" Fang Youqun almost didn't laugh, "Brother Yang, isn't your statement too outrageous? If you say that killer whales or humpback whales are invincible fish, it makes sense, but wrasse is invincible? It's just that small What does it use to be invincible?"

"The invincible I said is not the same as the invincible you think." Xiang Yang said with a smile: "When I say that the wrasse is invincible, I don't mean how strong the wrasse is in fighting, but that the wrasse has no power. enemy."

"No enemies?" Fang Youqun shook his head like a splashing drum. "That's even more impossible. This is not a poisonous fish. How could there be no enemies?"

"There is a word called benevolence is invincible. I think this word is just right to describe wrasses. Wrasses are very enthusiastic about the noble cause of "saving lives and healing the wounded". They have set up "free hospitals" in the ocean for generations. "Giving virtue and doing good deeds" treats all fish equally and responds to their needs. Over time, there are not many marine life that will attack wrasse in the entire ocean."

Fang Youqun opened his mouth wide, as if he was listening to the Arabian Nights.

In fact, what Xiang Yang said is true.

In 1971, a biologist in the Netherlands discovered that a lot of marine fish often gather around wrasses while observing fish.

There are all kinds of fish in these sea fish, there are docile vegetarians, there are weak ones that can only prey on scallops or conch, there are also fierce marine predators, and even terrifying creatures like sharks.

However, when those sea fish met the wrasse, they formed a circle and did not interfere with each other, just like a lion and a zebra drinking water calmly at the water source in a prairie in a certain video, which is indescribably weird and peaceful .

Later, biologists discovered through observation that most of the marine fish surrounding the wrasse were "sick fish".

When people are sick, they should ask a doctor for diagnosis and treatment.

Cats and dogs will find herbs when they are sick.

Do fish have to wait to die when they are sick?

The answer is no.

Biologists and scientists have discovered through observation that fish actually have their own doctors.

Among them, the wrasse is one of the fish doctors.

Especially the double-banded kingfish species among wrasses, they seem to have inherited memories, they are born with extremely superb medical skills, and they are simply rejuvenated. Many of them seem to be dying soon, and they are already powerless. Sea fish that have died, as long as they touch the double-striped wrasse, they will be alive and kicking again in a few minutes.

In one set of experiments, scientists put a group of fish with infected tissues and parasites in a tank containing wrasses.

The group of sick fish were sick at first, and they all looked listless.

However, when they saw the wrasse, their eyes immediately glowed, as if they were shining back, and they immediately swam to the wrasse to wait for treatment.

And the method of the wrasse made the researchers who did this set of experiments exclaim inconceivable.

The infected tissue on the sick fish is removed by the wrasse.

The parasites on the sick fish are eaten directly by the wrasse as snacks.

What's even more amazing is that a carnivorous fish with infected tissues in its mouth opened its mouth immediately after seeing the wrasse, and the wrasse was not afraid of being eaten, and swam directly to the carnivorous fish Heal it in the mouth of the human being.

That carnivorous fish really didn't eat the wrasse. On the contrary, it loved the "doctor" who treated him very much, stayed at the bottom of the water very quietly, and showed the injured part unreservedly on the wrasse. In front of the fish "doctor", even the most fragile fish gills allow the wrasse to come in and out of it.

A diver once took a group of very interesting videos underwater.

A group of sea fish of different types and sizes lined up quietly on the seabed waiting for the treatment of the wrasse.

At this moment, a ferocious bull shark ran over to make trouble.

The diver felt sorry in his heart, thinking that the fish would definitely panic and run away, and that video recording would definitely end.

As a result, the development of the matter was far beyond the photographer's expectations.

Including the wrasse, the fish did not escape at all.

Fish of different species, groups, and sizes all surrounded the wrasse together. The smaller fish worked together to protect the wrasse, while the stronger fish worked together to drive away the ferocious bull shark. , and then the school of fish rectified the order by themselves, lined up again, and quietly waited for the wrasse to heal themselves.
