My Deep-sea Fishery

Fang Youqun's hands pressed slightly, breaking on the biscuit sea urchin's body.

"I don't think the shell of this thing is very strong, why, except for cod, can't bite its shell?" Fang Youqun asked.

"That's not true. There are many shelled creatures in the ocean, and there are many ways to break their shells." Xiang Yang said.

"Brother Yang, didn't you just say that apart from cod, biscuit sea urchins have no natural enemies?" Fang Youqun questioned.

Xiang Yang smiled and said, "The reason why the biscuit sea urchin has no natural enemies is not how hard its shell is."

The edible part of biscuit sea urchins is very small, and there are hard shells on the surface. Therefore, in the entire ocean, few marine life are interested in biscuit sea urchins. Even sea dogs who love sea urchins do not eat biscuit sea urchins. of.

However, among the cod, there is a sturgeon called ocean cod, and sometimes it needs to swallow some **** sea urchins to help its digestion.

"Speaking of which, the reproduction ability of biscuit sea urchins is very terrifying." Xiang Yang said suddenly.

"Oh?"

Everyone became interested in an instant and looked towards Xiang Yang.

Fang Youqun directly asked, "How scary is it?"

Xiang Yang pondered for a moment, and then said: "During the reproduction of biscuit sea urchins, female biscuit sea urchins can eliminate 400 million eggs at a time, and male biscuit sea urchins can excrete 100 billion sperm at a time."

Hearing this, everyone took a breath.

With this way of multiplying biscuit sea urchins, and there are no natural enemies in the ocean, then the whole sea shouldn't have been occupied by biscuit sea urchins long ago?

In fact, the normal embryos of biscuit sea urchins can develop normally after many morphological changes and changes in diet.

Every time the shape changes, the biscuit sea urchin will die in large numbers. In the end, the one that really survives can be said to be one in a million.

"Okay, this biscuit sea urchin is worthless, throw it back into the sea." Xiang Yang said with a smile.

Fang Youqun nodded, and in accordance with Xiang Yang's request, he threw the biscuit sea urchin to the bottom of the sea.

The biscuit sea urchin thing came to an end, and everyone continued to clean up the catch on the deck.

Although the number of catches in this net is small, Xiang Yang is still standing by the catch, his eyes fixed on the fish pile, whether it is a treasured marine fish or a dangerous marine fish, Xiang Yang can spot it at a glance. .

"Fuck." Suddenly, a crew member squatting on the edge of the fish pile picking eagle pomfret exclaimed, and then suddenly jumped up from the place.

"What's the matter?" Xiang Yang asked quickly.

"Captain, there are jellyfish." The crew said.

Xiang Yang was shocked, and quickly said: "Okay, I see, you step back, I'll take a look."

Xiang Yang walked to the place and looked down. There was a strange sea creature with sky blue that looked a bit like a starfruit and was transparent all over.

"This jellyfish is very beautiful, what kind of jellyfish is this?" Fang Youqun came over and asked.

Xiang Yang shook his head speechlessly, stretched out his hand directly, and grabbed the strange marine creature with one hand.

Fang Youqun hurriedly shouted: "Captain, be careful."

"Be careful? This thing is called sea walnut, it's not a jellyfish at all."

The appearance of the sea walnut is indeed very similar to the jellyfish.

But in fact, the difference between the sea walnut and the jellyfish is a total difference of tens of thousands of miles. Except that they are both marine organisms, they have almost nothing to do with each other.

"We were lucky, and we got a azure sea walnut."

Although sea walnuts are distributed worldwide, the distribution of some beautiful colors is very limited. Such blue sea walnuts generally only exist in extremely cold waters.

"Is this thing an animal or a plant? It's transparent, why didn't I see any internal organs in it?" Fang Youqun asked.

"The sea walnut is a very simple animal. It has no heart, eyes and ears, and no blood or bones in the body." Xia Pengjie answered.

Xiang Yang pondered for a moment, and suddenly said, "Xia Pengjie, your whole answer is inaccurate."

"Is it a plant?" Fang Youqun wondered.

Xiang Yang shook his head, "Of course it can't be a plant, but if it is simply an animal, it would be wrong."

Now everyone is puzzled.

It's not a plant, and it's not an animal, so what is it?

Xiang Yang said: "There are all kinds of animals living on the earth today, and there are many kinds of creatures, but hundreds of millions of years ago, there was no life on land, and there were only a few creatures in the ocean."

Everyone nodded.

Everyone knows this. About five to six billion years ago, there were only a few animals on the earth, such as worms, sponges, and jellyfish.

"After hundreds of millions of years of evolution, the once worms have now evolved countless branches. Sponges and jellyfish have hardly changed from hundreds of millions of years ago. As for sea walnuts, in fact, in the early years, biologists and natural scientists also made it. It is not clear whether it is an animal or a plant, so they have a special classification called phyto-animals." Xiang Yang said.

From the outside, the sea walnut is indeed more like a plant.

Therefore, biologists named sea walnuts with fruits and vegetables, and named them sea walnuts.

However, the sea walnut is indeed an animal, and it is also a kind of animal without meat. All kinds of small crustaceans and small fish and shrimps are the food that sea walnuts like to eat. Sometimes, the hungry sea walnuts will be right. Similar to start.

"Captain, can this sea walnut be sold for money?" Fang Youqun asked.

Xiang Yang nodded, "Of course."

Fang Youqun's eyes lit up when he heard the words, "Then is this thing worth the money?"

Xiang Yang smiled and shook his head, "I don't know yet."

Fang Youqun was anxious immediately, "Brother Yang, what is worth is worth, and what is worthless is worthless. How can I not know?"

Xiang Yang pointed to the carambola-like diamond-shaped edges around the sea walnut body and said: "These parallel bands distributed on the sea walnut body are actually its luminous bands. At night, it can emit light. Very beautiful light, especially when it is swimming in the water, the long tentacles dragging behind will also emit a pleasant blue light that flickers like a neon."

When Fang Youqun heard it, he immediately understood, "Brother Yang, you mean, is this sea walnut worth any money? You have to wait until the night to see if the light it emits is good?"

Xiang Yang nodded, "Yes, that's right, even if it is the same azure sea walnut, it can also emit a beautiful blue light. At night, the brightness of the light on their tail tentacles is different, and the difference caused by it is also a difference between clouds and mud."

Fang Youqun hurriedly said, "Captain, I will put it in the water tank first."
