My Deep-sea Fishery

Li Chao pointed to the bungalow and asked, "Brother Xiang, why did you bring us here?"

"come in."

After Xiang Yang finished speaking, he walked towards the house first.

Li Chao and Xu Yue looked at each other halfway, and then followed.

This house is the old house of Xiang Yang's third uncle's family. Since the third uncle's family has gone out to make a living, this old house has been vacant and has not been lived in for many years.

"The house has been in disrepair for a long time and is a bit dilapidated, but you don't have to worry about safety issues. There are some treasures hidden here." Xiang Yang said.

"Baby?" Li Chao and Xu Yueban's eyes lit up.

"Actually, they are some sea fish that I think are valuable, but I can't find a buyer for a while." Xiang Yang opened the door, and there were two rows of fish tanks neatly arranged in the somewhat dim living room. Each fish tank contained various figures. Beautiful daughters, big and small, with different colors and strange shapes, if ordinary people came, they would definitely be dazzled at first sight.

There was a group of festive and cute fishes in a fish tank with exaggerated body color and nimble swimming that caught the attention of Li Chao and Xu Yueban.

"This is a clownfish. It's very difficult to catch. I managed to catch these." Xiang Yang said with a smile.

When Xiang Yang met the clownfish for the first time, he was fascinated by the appearance of the clownfish. Although there are not many colors on the clownfish, they are very eye-catching, making people unforgettable, especially on its face. The white spots are particularly joyful, which makes people feel happy when they look at them.

"I found these clownfish among giant sea anemones when I was fishing for sea anemones," said Xiang Yang.

Clownfish, also known as anemonefish, is a general term for a variety of tropical seawater fish that can co-exist with sea anemones. They are distributed in various tropical seas around the world. There are currently 28 known species of clownfish, most of which are All of them are of the genus Amphipeus, the largest of them is 11 cm in length.

Each of the clownfish caught by Xiang Yang has one or two white stripes on its head, resembling the oil paint on the face of a clown in a circus.

Li Chao looked at Xiang Yang and asked doubtfully, "Can the clownfish be fed alone without the sea anemone?"

Xu Yueban also wondered, "I've also heard that clownfish and sea anemones have a symbiotic relationship."

The so-called symbiosis refers to the existence of a symbiotic relationship between two or more species in the biological world, which is interdependent and mutually beneficial.

This symbiotic relationship can be a long-term behavior or a short-term behavior. Generally, two species in this relationship either live together or die together, and neither can do without the two parties.

"There is a symbiotic relationship between the clownfish and the sea anemone, but it doesn't mean that it can't survive without the sea anemone. It's just that its body color is very bright and easy to be spotted by enemies. It doesn't have the ability to protect itself, so it relies on the sea anemone. The toxin is just for protecting itself, I keep it in the fish tank, it has no natural enemies, why can't it survive?" Xiang Yang asked rhetorically.

Many weak marine creatures must find a strong backer if they want to survive in the extremely dangerous ocean world.

The clownfish is one of many weak sea creatures, so it chose the sea anemone as its backer.

So can sea anemone be a backer for clownfish?

The answer is yes, sea anemones have tentacles that can secrete venom, which can protect themselves and clownfish from being attacked by other fierce sea creatures.

Moreover, the clownfish is extremely small, even if it only eats the food scraps left by sea anemones, it can still maintain its own living needs.

So would the sea anemone be willing to be a backer for the clownfish?

The answer is yes.

Sea anemones are more than happy to provide shelter to clownfish because sea anemones cannot actively attack their prey.

Kong has a strong toxin but can't take the initiative to attack. If the sea anemone can't find a way to get its prey to come to its door, it will starve to death.

So how exactly do sea anemones get their prey to come to their door?

The answer is clownfish.

The clownfish can easily attract other fish to approach by using its body and its bright colors, providing opportunities for sea anemones to prey.

Moreover, the clownfish is also the "personal doctor fish" of the sea anemone. After living with the sea anemone, the clownfish will take the initiative to help the sea anemone remove necrotic tissue and parasites. In addition, the clownfish is also responsible for the cleaning of the sea anemone.

The clownfish parasitic with sea anemones will reduce the probability of food debris remaining in the sea anemone bushes through fast swimming.

"And not every clownfish can get along well with sea anemones, at least most of the clownfish have a bad relationship with sea anemones in the early stage." Xiang Yang laughed.

Clownfish don't choose suitable sea anemones to parasitize until they are adults.

Many clownfish are accidentally injured by sea anemones when they first live in symbiosis with sea anemones.

Xiang Yang pointed to a beautiful clownfish with an orange background, a black back, and two sky blue stripes behind the eyes, and said: "When I caught this clownfish, it hadn't reached a symbiotic relationship with the sea anemone, and it was approaching cautiously. The tentacles on the giant sea anemone, as a result, the sea anemone moved, and it was poisoned and overturned on the bottom of the sea. If I hadn't happened to pass by, it would have been poisoned to death by the sea anemone."

Li Chao blinked, "The clownfish will be poisoned by the sea anemone?"

Xu Yueban also had a look of disbelief.

"Yes, the toxins of sea anemones are also useful to clownfish. Clownfish do not have the ability to be immune to the toxins of sea anemones." Xiang Yang affirmed.

"Clownfish cannot be immune to sea anemone toxins, so how does it achieve symbiosis with sea anemones?" Xu Yueban asked.

"A species secreted by the poisonous tentacles of sea anemones." Xiang Yang said.

The so-called highly poisonous thing must have an antidote within seven steps.

The tentacles of sea anemones are both highly poisonous and detoxifying.

The tentacles of sea anemones can secrete an unknown substance, which can not only neutralize the toxins of the stinging cells on the poisonous tentacles, but also inhibit the ejection of the stinging cells.

When clownfish first come into contact with sea anemones, they need to carefully touch the poisonous tentacles of the sea anemone, and keep scratching their bodies on the poisonous tentacles of the sea anemone, so that the whole body is covered with the unknown substance secreted by the poisonous tentacles of the sea anemone.

When the clownfish is completely covered by the unknown substance, it is the "self" of the sea anemone. It no longer needs to be afraid of being stabbed by the poisonous tentacles of the sea anemone, and can nest in the sea anemone bushes with peace of mind. reproduce.

Of course, as soon as the bred anemone hatches, it will immediately leave its parents and live in the water layer. It will not find a new anemone until it reaches adulthood, repeat the tradition left by its parents, and continue to reach new heights with the new anemone. Symbiotic relationship, and build nests in sea anemone bushes to reproduce the next generation.
