Chapter 1185: Lighthouse jellyfish

But in this sea, there are many sharks. How could this one be the big shark they saw before!
When Li Yu said this, Zhao Zhongyao took a closer look at this big shark for a while, and he felt that this big shark was really the big shark they had encountered before. Because he saw some wounds on the back of this big shark, which was caused by the impact of Zhao Zhongnian in a speedboat.
After seeing this situation, Zhao Zhongyao said to Lin Xiaowei and the others: "This big shark is the big shark we encountered before. It seems that we are also related to this big shark!"
Upon hearing what Zhao Zhongyao said, Li Yu said with some confusion: "Mr. Zhao, how do you judge, don't all these sharks look the same!"
"Look carefully at the back of this big shark, are there some small wounds on it?" Zhao Zhongyao said to Li Yu and the others.
Li Yu and the others listened to Zhao Zhongyao's words, and looked at the big shark outside the porthole that was still swimming outside their spacecraft.
At this time, Li Yu saw the wounds on the back of this great shark, and now he can be sure that this great shark is the same great shark they encountered before.
"Hey, what Mr. Zhao said is, look, this big shark has some wounds on its back. This was caused by Mr. Zhao hitting the back of this big shark when he drove a speedboat to rescue Sun Ming."
When Li Yu said this, Lin Xiaowei and Sun Ming also looked at the wounds on the back of this big shark. They can also be sure that this big shark is the same big shark they encountered in this sea before. shark.
"This is really interesting! This time when we came to this sea in a spacecraft, we encountered the big shark that attacked us last time. It's a coincidence!" Lin Xiaowei looked at the back of this big shark. The wound, he also felt that this big shark must have been the one that attacked them when they were swimming here.
"Yeah! This big shark dared to challenge us. Or, let's clean him up now! Is there any weapon that can attack on our spaceship! We let the spaceship fire some bullets, Shot this shark."
Sun Ming had a bit of hatred for this big shark! After all, he almost became the delicacy of this big shark before.
On this moon landing spacecraft, there are also some weapons used for self-defense. After all, it is unimaginable that something will be encountered in the universe. This spacecraft must have the ability to defend itself.
Sun Ming's words made Zhao Zhongyao clear. He heard Sun Ming's words and said: "Sun Ming, I know you are full of hostility towards this shark. But we are now driving the spacecraft here. The experiment in the deep sea is not here to seek revenge. Let's continue to sneak down! This big shark, just leave it alone."
After hearing what Zhao Zhongyao said, Lin Xiaowei came to persuade Sun Ming: "Sun Ming, what Zhao said is that we are not here to avenge you when we come to this sea by spacecraft. We are here to do experiments. We don’t care about this big shark. Now, when we are advocating the protection of wild animals, we don’t know how many shark fins will become humans’ dishes every year! This big shark, although now Still swimming freely in the water, who knows that for a while, some criminals will be poached! We just don’t have to worry about this big shark."
Sun Ming heard what Lin Xiaowei said and felt reasonable, so he smiled and said: "How can I be so stingy! How can we humans have trouble with a shark! What Zhao said is that we should still finish The task of the experiment is heavy. We don't care about this big shark."
After hearing Sun Ming's words, Zhao Zhongyao said to Lin Xiaowei and the others: "Well, you don't care about this big shark, let's continue diving quickly!"
"Okay, we don't care about this big shark. Let's quickly complete the spacecraft sneak mission this time!" Lin Xiaowei followed Zhao Zhongyao's words and said so.
After that, Lin Xiaowei drove the spacecraft and continued to dive into the deep sea.
At this time, the spacecraft had already dived to a depth of more than 100 meters. That big shark was originally the spaceship that had been following them. Wandering around the portholes of their spacecraft from time to time, as if it had seen Sun Ming through the porthole, and wanted to swallow Sun Ming!
Li Yu saw this big shark wandering by the porthole from time to time, he watched Sun Ming play a joke: "Sun Ming, you think this big shark recognizes you, and it wants to eat you! If it didn't eat you once, it will never forget you!"
After hearing what Li Yu said, Lin Xiaowei also watched Sun Ming joking: "Sun Ming, please go over and shake hands with this shark! Otherwise, it will always follow us!"
After hearing what Lin Xiaowei said, Sun Ming smiled and said, "Haha, isn't it? Then I will shake hands with this shark and say okay!"
After Sun Ming finished speaking, he walked to the porthole of the spacecraft. He stretched out his hand and placed it on the porthole. Then he looked at the big shark and said, "Hey, big shark, let's shake hands and say okay! You don't want to eat me. Now, I’m still young! I’m not married yet! It’s a bit of a loss to let you eat like this! You should eat some small fish! It’s useless if you keep following us like this, our spaceship is much better. Don't make us angry, or we will kill you."
The big shark seemed to have seen Sun Ming and recognized him again. He leaned his head to the side of the porthole and opened his mouth wide, thinking about eating Sun Ming! But through the thick and sturdy portholes, it naturally has no choice but to take Sun Ming.
When Sun Ming saw the appearance of this big shark, he was really angry and funny.
Now look at Sun Ming pointing at the head of this big shark and smiling: "Haha, you still want to eat me! Then you can eat it! Why don't you come in! I think you have nothing to do with me, you just If I look at this delicious meal, I just can’t eat it!"
"Haha! Haha! Haha!---"
After Sun Ming said these things, Lin Xiaowei and Li Yu naturally laughed when they heard Sun Ming's words. Zhao Zhongyao, who was connected to the surface of the sea, heard Sun Ming's words and couldn't help laughing twice.
However, things are really amazing. After Sun Ming said this, the big shark seemed to understand Sun Ming's words. It looked at Sun Ming, and had to turn its head and swim away.
The spacecraft continued to dive, and now it has dived to a depth of five hundred meters. At this depth, there is no longer a finger in the sea.
Zhao Zhongyao was above the sea, and through the monitoring equipment, he could not see the spacecraft in the sea. So he ordered Lin Xiaowei to turn on all the photo equipment in the spacecraft. Both the photo system inside the spacecraft or the lighting system outside the spacecraft are all turned on.
The lighting system on the spacecraft is very advanced. The power of a searchlight installed outside the spacecraft exceeds 10,000 watts. It can illuminate the sea water more than 100 meters near the spacecraft.
When Lin Xiaowei turned on all the lighting equipment on the spacecraft, the inside and outside of the spacecraft were almost as if they were on the sea. Of course, this artificial light can't be compared with sunlight.
However, now that Lin Xiaowei and the others are inside the spacecraft, they can see far away. While Zhao Zhongyao is on the sea surface, he can also see the spacecraft under the sea through monitoring equipment.
Lin Xiaowei saw that the spacecraft had already dived to a depth of more than 500 meters. He looked at Sun Ming and Li Yu and said, "You said, in such a deep sea, what creatures are there!"
After hearing what Lin Xiaowei said, Sun Ming thought for a while and said: "Of course there are no living things in such a deep sea. Even the sun can't shine in here, so what living things can there be!"
Sun Ming knew little about marine biology. He listened to Lin Xiaowei and thought that there would be no living things in such a deep sea.
But Li Yu heard Sun Ming’s words and looked at him and said,
In the depths of the sea several hundred meters deep, there will still be some living things. Let’s take a look! There will be some in the depths of the sea. Amazing creature."
Lin Xiaowei heard Li Yu's words and said: "Yes, there will be creatures in the depths of the sea. Let's watch it slowly!"
In this way, the three of Lin Xiaowei and the others were watching the movement in the sea outside quietly. At first they couldn't see anything, but when the spacecraft continued to dive to a depth of more than 800 meters, they suddenly saw the spacecraft outside. There are many circular things moving up and down.
"What's that?" Sun Ming sat beside the porthole. He chose to see that outside the spacecraft, many round creatures suddenly appeared.
After Sun Ming said this, Lin Xiaowei and Li Yu also looked outside through the portholes. The two of them knew what the round creature outside was.
"This is a lighthouse jellyfish. It is a deep sea jellyfish." Lin Xiaowei said first.
"Yes, this is the lighthouse jellyfish, which can survive several hundred meters below the surface of the sea." Li Yu echoed Lin Xiaowei's words.
"Ah! This jellyfish is really amazing. It can survive in such deep sea water. This is really beyond our imagination."
For Sun Ming, it was the first time he heard that there would be jellyfish living in such a deep sea!
At this time, Zhao Zhongyao also saw the situation near the spacecraft through the monitoring equipment. He also saw many lighthouse jellyfish surrounding the spacecraft. It seems that they were also attracted by the lights of the spacecraft.
Zhao Zhongyao is also very familiar with this lighthouse jellyfish.
The diameter of lighthouse jellyfish is only 4 to 5 millimeters and belongs to the class of Hydroids. They are predatory organisms that can reproduce asexually from hydroids. They are the only known organisms that can return from sexual maturity to larval stage. In theory, this cycle can be repeated continuously, that is, the lighthouse jellyfish can live forever without facing death.
Once a scientist who studied lighthouse jellyfish observed 4000 lighthouse jellyfish and confirmed that all of them can rejuvenate and none of them died. A kind of lighthouse jellyfish-the lighthouse jellyfish will return to the hydroid state after sexual maturity, and this process can be repeated indefinitely.
According to the newspaper, this jellyfish is the only animal that can theoretically live forever as long as it is not eaten or died of illness (Bacillus coli can be immortal because of its circular DNA.). The lighthouse jellyfish is about 4 to 5 mm long, and it takes 25 to 30 days to reach sexual maturity at a water temperature of 20 degrees Celsius.
Lighthouse jellyfish mostly live in tropical waters. It is carnivorous and feeds on plankton, small crustaceans, hairy species and even small fish. Due to the mechanical and chemical stimulation of the food, this hydroid animal stretches its tentacles and releases barbed wire sacs to entangle, paralyze, and poison the prey, and then feed the food into the mouth.
The mucus secreted by the gland cells in the mouth area is conducive to the swallowing of food. After the food enters the gastric cavity, the gland cells in the gastric layer begin to secrete proteases to decompose and digest the food to form many polypeptides. Can be mixed and promoted.
After this extracellular digestion, the intracellular digestion process begins. The pseudopodia that nourishes the muscle cells engulf food particles and form a large number of food bubbles in the cell. After the acidic and alkaline chemical processes, nutrients diffuse from the cells. The effect is delivered to the whole body.
Zhao Zhongyao also knows something about this kind of marine life. When he saw such a miraculous creature, he said to Lin Xiaowei and the others: "Do you know what this creature is?"
Lin Xiaowei heard what Zhao Zhongyao said, "Isn't this kind of creature a lighthouse jellyfish!"
After hearing what Lin Xiaowei said, Zhao Zhongyao smiled and said, "Yes, this is a lighthouse jellyfish, a creature that can live forever."
"What can be immortal." Lin Xiaowei only knows the life of lighthouse jellyfish, but he still doesn't know much about the life habits of lighthouse jellyfish.
Now when he heard Zhao Zhongyao say that this kind of jellyfish can live forever, he feels very strange. After all, he has not heard of any creature that can live forever.
Sun Ming and Li Yu heard what Zhao Zhongyao said, of course they also felt very strange. Sun Ming also asked incomprehensibly: "Mr. Zhao, what are you talking about, this kind of lighthouse jellyfish can live forever, what is going on, can you tell us in detail!"
"Yes! Mr. Zhao, you can tell us some knowledge about lighthouse jellyfish!" Li Yu is naturally very curious now, and wants to know some knowledge about lighthouse jellyfish.
