Xiang Yang actually tends to believe that sea walnut is a plant.
Because the appearance of sea walnut really looks like a plant.
The fishermen in the past also named it after plants. Walnut is a plant.
However, although there is still controversy in the biological science community about whether sea walnuts are animals or plants, it is generally believed in general academic papers that sea walnuts are animals.
Because sea walnuts have many characteristics of animals, such as eating meat, various small crustaceans and small fish and shrimps are on their menu. When food is extremely scarce, they will devour their own kind without any discrimination. This is a characteristic that no other plant has.
"Cat's eye jellyfish, what a good thing." Zhang Qicheng said with a smile, "This cat's eye jellyfish can glow. There are several parallel light bands around its upper body and in the middle of its body. It can emit beautiful and dazzling light in a dark environment. Especially when it swims in a zigzag manner in the water, the tentacles behind it will emit a pleasing blue light that flashes like neon."
Xiang Yang couldn't smile, and even looked a little ugly.
Any old fisherman who is familiar with sea walnuts does not hope to catch such a creature one day, especially when this creature appears very close to his permanent port.
Because sea walnuts will devour oyster larvae, eggs and fry without restraint, and their reproductive capacity is extremely terrifying, they pose a devastating threat to many fish.
In the 1990s, the fishery resources in the Black Sea suddenly decreased significantly, the fishing industry was in a depression, countless fishermen lost all their money, and the prices of seafood in the market were very low.
The local officials could no longer sit still and immediately sent people to investigate.
Soon, the results of the investigation came out. It turned out that an American cargo ship accidentally transported a batch of sea walnuts to the Black Sea.
After that batch of sea walnuts brought the Black Sea, they immediately reproduced on a large scale. Their reproductive ability was so terrifying that one sea walnut could give birth to 8,000 offspring in a single day.
By the time local scientists launched an investigation, it was too late. The number of sea walnuts in the Black Sea was conservatively estimated to have reached 1 billion tons. They had eaten most of the plankton in the Black Sea like locusts, causing irreparable damage to the Black Sea's fishery resources.
The Black Sea's main economic fish, anchovies, lost their food source and their numbers plummeted. Fishermen were unable to catch any more fish and went bankrupt.
It’s not just the Black Sea that has been poisoned by sea walnuts.
The Caspian Sea was once "invaded" by sea walnuts.
Even sturgeon, the main raw material for caviar, which was once one of the economic pillars of the Caspian Sea, has been completely wiped out by sea walnuts.
In order to eliminate this beautiful but rampant strange creature, local fishermen collected huge amounts of money and purchased a large number of oval melon jellyfish from other places to prey on sea walnuts. It took several years to clear all the sea walnuts.
After the Black Sea incident and the Caspian Sea incident, the sea walnut was given another name, "monster". Many fishermen called this strange creature a monster and hated it to the core.
Once some fishermen discover this creature, they will immediately gather several large ships and go to that sea area. Several large ships will sail side by side, dragging a family-destroying net with a grappling hook at the stern. They will go back and forth in that sea area to scrape the nets regardless of the cost. The sharp claws can even crush the reefs on the seabed into pieces.
After Xiang Yang told everyone about the characteristics of the sea walnut, many crew members were stunned.
Fang Youqun even screamed in surprise: "A sea walnut can reproduce 8,000 offspring in one day?"
"Is this the sow giving birth to piglets?"
Xiang Yang rolled his eyes and said, "If your sows can give birth to 8,000 piglets a day, I will stop fishing and start farming with you."
Xiang Yang picked up a sea walnut and said, "The reason why the reproduction ability of sea walnuts is so terrifying is that the reproduction system of sea walnuts is very simple. Each sea walnut can produce sperm and eggs at the same time, and their young grow very fast. They are like the sponge Bob that we raised when we were children and could grow up in a water cup. Water accounts for the vast majority of their body composition, and only a small part is the mesoglea."
Chen Qingsheng asked Xiang Yang, "Brother Yang, what should we do now?"
Xiang Yang smiled indifferently, "What can we do? Sea walnuts are distributed worldwide. As long as they are not invasive species, their distribution range is mostly very limited. In this sea area, with the presence of sea walnuts, we can still catch thousands of kilograms of fish with one net, which proves that these sea walnuts have lived here for generations. They also have their own natural enemies. The number is always maintained at a certain number, and the range of activities is also very limited. They cannot cause a devastating blow to other fish."
"Then? Shall we continue cleaning the catch?" Chen Qingsheng asked.
Xiang Yang nodded, "You guys continue to clean up the catch, I'll go down to the bottom of the sea to take a look."
"Okay, I'll go get you a diving suit." Chen Qingsheng trotted towards the cabin.
Soon, Xiang Yang put on his diving suit, put on his helmet, and climbed down the ladder.
The water in this sea area is deeper than Xiang Yang expected.
When he reached the bottom of the sea, Xiang Yang immediately discovered that the water in this area was at least five hundred meters deep.
The sea water is five hundred meters deep, which is beyond the scope of ordinary human activities, but Xiang Yang is obviously not among these ordinary people.
Xiang Yang swam in front, and the killer whale followed behind, and the man and the killer whale sank towards the bottom of the sea.
After diving more than 400 meters, Xiang Yang finally found the figure of sea walnut.
I saw a group of sea walnuts emitting soft blue light, swimming leisurely on the seabed.
The eight tentacles behind their big heads flapped rhythmically, making them look like elves.
What was very magical was that a sea walnut that swam past Xiang Yang seemed to be injured, and the injury was very serious, with almost half of its body gone. What was amazing was that this sea walnut with half of its body missing seemed to be uninjured, and it also followed the flow, gently waving its tentacles and swimming slowly in the dark sea.
Xiang Yang looked at the injured sea walnut and didn't make a fuss.
The reason why sea walnuts are called monsters is not only because their reproductive ability is extremely abnormal, but also because their vitality is equally abnormal.
The regenerative ability of sea walnuts is even stronger than that of sea cucumbers. If their tentacles are broken, they can regenerate the broken arms. Even if half of their bodies are gone, they can still regenerate into a complete individual.
Xiang Yang swam towards the direction of the sea walnuts.
The sea walnuts did not scatter when Xiang Yang approached. They had no eyes and could not see Xiang Yang. Even if they saw him, they had no brains and would not feel afraid.
