Ling Fei was immediately frightened, he heard that jellyfish are all poisonous, some of them can even kill people lightly, and the poison is very fast, he won't explain here today, right?

Thinking of this, his heart felt a wave of fear. After a while, he noticed that there was no discomfort, and the red spot on his arm did not spread, so he breathed a sigh of relief, it seems that this jellyfish is not very poisonous.

Moreover, the jellyfish did not seem to think of him as food, and ignored him, and continued to float upward, its long tentacles dragging behind it like a ribbon.

Ling Fei was glad for a while, but for the sake of safety, he still avoided those tentacles and swam quickly towards the surface of the sea.

"Ling Fei, what's wrong with you?

"I just encountered a very big jellyfish on the bottom of the sea, and I was stung by it, and my arm was numb, can you help me see if it is poisoned?" Ling Fei said.

He is also sick and goes to the doctor, regardless of whether the tourist understands it or not.

"Is there a jellyfish here?Ling Fei, are you okay?, how do you feel?" the others said when they heard that he had been stung by a jellyfish.

"It's just that my arm is a little itchy and a little painful, and I don't feel anything else. Ling Fei said.

"It's all red and swollen, and I don't know if it's poisoned, so why don't we go back? The tourist noticed the abnormality on his arm and said with some concern.

"Don't panic yet, you better go and take a look at the uncle who drove the boat! Another tourist reminded him.

Everyone thinks it makes sense. So they went to find the uncle who was resting in the cabin.

"Uncle, come and see, Ling Fei was stung by a jellyfish. ”

The villager had heard that someone had been stung by a jellyfish. I was also taken aback, now is the time for Tangjia Village to build a tourist area, if something happens, the impact will be very large, and it may even make all efforts in vain.

In terms of personal safety, they have done a lot of work, and no one dares to be negligent.

Look at his wounds. The villager was also a little anxious, there were not many jellyfish in the waters of Fisherman's Bay, and he didn't know much about it. Coupled with the fact that they used to fish on boats and would not drill into the sea every day as they do now, how many people would be bitten by jellyfish?

"Well, let's wash the wound with seawater first. The villager said. He still has this basic common sense.

Bitten by a jellyfish. Do not rinse with fresh water, which will exacerbate the release of jellyfish toxins and have the opposite effect.

"Didn't the TV show say you were going to rinse with urine?" muttered another tourist.

He had seen a show on TV about someone who had been stung by a jellyfish and was cleaned with urine.

"It's not as good as using sea water and white vinegar, and rinsing with urine with too low salinity will have the same effect as fresh water. In fact, this is done to keep the salt concentration of the solution inside and outside the stinging cells of the jellyfish in balance, once it is destroyed. More toxins will be released. The top student explained.

"You have stinging cells in this wound, you have to scrape it off. Rinse well again and apply some antibiotics. Also, don't go outside, don't let the sun get to the wound, the sun can also exacerbate the release of toxins. ”

Another experienced tourist also offered to build yì, who often goes out to sea with friends and knows a little about these situations.

In addition, it is necessary to pay attention to the appearance of abnormal symptoms such as difficulty breathing, chest pain, difficulty swallowing, voice changes, sore throat, dizziness, abnormal heartbeat, sudden weakness, nausea, muscle spasms, loss of consciousness, etc. If these reactions occur, you should be taken to the doctor immediately.

"Most of the poison of jellyfish is neurotoxin, which is more harmful to the body, so it is better to go to the hospital to deal with it and inject antivenom serum, so that you can rest assured. Someone mentioned yì.

Everyone had to let that uncle sail back, which is really a disadvantage!

"Don't worry too much, generally speaking, as long as you don't die on the spot, you won't die. Fortunately, it wasn't stung by a box jellyfish, otherwise I don't know if you could swim up, its toxin can kill people in thirty seconds, and it can only last a few minutes at most. The scholar said to Ling Fei.

He knew that the box jellyfish was the most poisonous animal in the world, and its tentacles grew thousands of stinging cells that stored venom, and the venom released by the stinging cells was a neurotoxin, and the poisonous cobra was even stronger, which could kill people in thirty seconds, and there was no time to rescue them.

What's more, it is very aggressive, often maliciously attacking other creatures, and once it encounters its prey, it never lets it go.

Moreover, it itself is only twenty or thirty centimeters long, but it has sixty tentacles that can reach more than three meters long, even if some creatures inadvertently scratch it, it will stimulate the tiny stingers on the tentacles, and put it to death.

Ling Fei's face turned white, it didn't sound like a comforting person, did he? Who knows what the general situation is? What time period does the spot refer to?

He subconsciously felt a hotter pain in his arm, and hurriedly urged his uncle to hurry up and start the boat.

"Look, what is this? Is it a jellyfish?" said someone at this time, pointing to the sea.

On the surface of the sea, an umbrella-shaped blue animal floats on the surface of the sea, shining beautifully in the sun, somewhat similar to the pictures of jellyfish that you usually see.

"It's really a jellyfish! It's a big one, Ling Fei, it can't be the jellyfish that stung you, right?" said one tourist.

"I guess it's about the same size and color as the jellyfish that stung me. Ling Fei looked at it for a while and said.

He knew that the jellyfish swam very slowly, and that the jellyfish swam here with the current, otherwise it would not be so coincidental.

Everyone suddenly became interested, and they all stopped on the side of the boat to watch, if it wasn't for Ling Fei's injury and going to the hospital, they all wanted to ask the uncle to drive the boat and go up.

"There's a turtle there, do you see that?" said someone excitedly.

"I saw it too, what kind of turtle is that?" the others found their focus under his guidance.

I saw a sea turtle swimming awkwardly in the sea in the distance, and its gray-brown body looked a little large, two or three meters long.

In the current, as if it had seen a delicacy, it flapped its limbs vigorously and approached the beautiful jellyfish, and soon pounced on the jellyfish, fixed it with its forelimbs, and then began to bite.

"It's like a leatherback turtle. The scholar said that he had never seen it, and he couldn't be sure, but the book said that the leatherback turtle was the largest turtle, and it had no shell, and its head was so large that it couldn't be retracted into the carapace, which was very consistent with the image of the turtle in front of him.

"Isn't the jellyfish poisonous? How dare it eat it? Is that jellyfish not poisonous? Then Ling Fei, you don't have to worry. A tourist said.

"Then you are wrong, sea turtles are the natural enemies of jellyfish, and in the stomach juice of sea turtles, there is a special substance that can dissolve the poison of jellyfish. The scholar said, as for what substance, he didn't know.

"In fact, many sea turtles have the ability to detoxify, so their diet also includes some poisonous creatures such as sponges. Maybe that's why they've got enough food to survive to this day? That's how they survive. However, this leatherback turtle will become extinct within a decade or two. ”

The scholar continued, with a faint sadness and powerlessness in his voice. Others are a little sentimental, and they may have known it before, but they weren't as impactful as they are now.

A living species is right in front of you, knowing that it is going extinct, but finding that you don't know what you can do.

In everyone's astonishment, the turtle tore the big blue jellyfish to pieces in two clicks, like tearing a plastic bag full of water, and then tasted the delicious food as if no one was around.

In fact, jellyfish also have their own evasion methods, because its tentacles are very sensitive to changes in water flow, and 100 tentacles can quickly react to changes in water flow in any direction.

Jellyfish have a special gland in their umbrella body that emits carbon monoxide, which causes the umbrella to swell. When a jellyfish encounters an enemy or a major storm, it automatically releases all the gas in its body and sinks to the bottom of the sea.

Some jellyfish can even shrink to a tenth of their original size. Once the sea is calm, it only takes a few minutes to produce gas that expands and floats itself.

It is by virtue of this "floating" jellyfish that has escaped the catastrophe of 650 million years and survived to this day.

It's just clear that in this encounter, it lost and became a ration for the turtles.

This kind of thing was new and interesting to these tourists, and it quickly diluted their sadness, and one by one they were judged, and some even tried to salvage it, but no one else agreed.

Ling Fei was so excited that he didn't even care about the injuries on his body, and ran to the side of the boat with the camera. It's a rare opportunity, so let's take a few more photos. As for the injuries on the body, it shouldn't be in the way, right?

"Jellyfish are the most water-rich creatures in the world!" someone sighed, looking so beautiful.

However, there is a good saying that the more beautiful something is, the more poisonous it is!

Jellyfish do not have a digestive system and circulatory system, and the captured food is directly digested and absorbed in the digestive glands, and the absorbed substances are directly transported through the digestive circulation cavity of guò coelenterates.

The flow of water in the digestive cavity can transport the digested nutrients to all parts of the body, and it also has a circulatory effect. Therefore, the water in the jellyfish basically replaces the circulation of blood.

Because of this structure, jellyfish require almost no oxygen, are extremely tenacious, and can survive in stagnant waters. They are able to appear in groups, dense distribution, and lead to the mass death of other marine animals in the area where they are located, and it is difficult to recover.

The prosperity of jellyfish is not a phenomenon of environmental improvement, but a manifestation of severe water pollution and environmental deterioration, and is one of the indicators of water pollution and environmental deterioration.

And their aggregation and reproduction lead to the mass death of zhì species, forming a vicious circle. (To be continued......)
