Recently, when the man was playing in the wild, he saw a dried crucian carp not far away. He happened to be passing by and put the crucian carp into the water.
The man's initial move was not because he was saving the fish, maybe he was curious, maybe he was bored, but it was certain that he didn't know the mentality of saving the fish.
However, soon after, a miraculous scene appeared, the crucian carp, which was still like dried fish just now, slowly moved its body after absorbing enough water.
Then, the mouth of the crucian carp also slowly moved, and it was more difficult at first, opening the mouth once, and after a while, it was possible to open the mouth a second time, but as time passed, the frequency of the crucian carp's mouth opening began to increase and it was resurrected from the dried fish.
After seeing this scene, some netizens below expressed doubts about it, however, there was one netizen below who expressed support and he thought it was true.
Because he also encountered this situation a few years ago, when he caught a dozen crucian carp in a farmhouse, and the crucian carp he caught was not put into the water, but in a basket made of bamboo.
We all know that the weather in the summer is very hot, and the water evaporates very quickly when it is outdoors in direct sunlight.
By the time he returned home from fishing, more than two hours had passed, and the fish had dried up, and it was as hard as a dried fish.
This kind of dried fish is not easy to pack and cannot be eaten. He came up with a solution, which was to soak the crucian carp in the water, and when the dried fish had absorbed enough water, it would be easier to clean up.
Who knows, in less than an hour, all of these crucian carp soaked in the water came to life, and they were all alive, which made him sigh that the life of the crucian carp is big, and the vitality is so terrifying.
From the above two examples, it can be seen that after turning into dried fish, crucian carp can indeed come back to life after being put in the water, which can't help but make people wonder, that is, why does crucian carp have such a terrifying vitality, and how does it do this?
Why is crucian carp still alive after being dried?
When it comes to the resurrection of dried crucian carp, one cannot help but think of a fish that is more vigorous and can survive after a few years out of water: the African "lungfish".
In terms of the time to get out of the water, the crucian carp will definitely not be out of the water for as long as the lungfish. In Africa, mud is used to make houses, and many times, barramundi is made into houses by African natives. A few years later, it rained and the wall peeled off, revealing the barramundi inside.
The ability to survive for a few years without eating or drinking, not to mention fish, is something that ordinary land creatures can't do, so how does the lungfish do it, crucian carp can survive by being dried into dried fish, and the lungfish will not die for a few years on land, is it the same?
Arguably one of the oldest organisms on Earth, the lungfish is more than 400 million years old, and it is an intermediate species between fish and amphibians, also known as living fossils.
Hundreds of millions of years ago, the earth's environment changed dramatically, and many fish gradually evolved into amphibians, but barramundi stopped evolving halfway through evolution.
Although evolution has stopped, it has also evolved some of the abilities that only amphibians have, that is, lungfish have also evolved lungs that can breathe on land.
When the dry season comes, when the river dries up, the lungfish wraps itself in mucus like a silkworm cocoon, which not only keeps the body moist, but also insulates bacteria and viruses.
Of course, the lungfish is not all wrapped, but also a tiny vent for breathing, and in addition to breathing with the lungs, the skin-rich capillary tubules of the lungfish can also absorb oxygen from the air.
When all this is done, the barramundi begins to reduce their metabolism and reduce their body's energy consumption to about 10% of its original level, so that it can last until the onset of the rainy season next year.
From here, it can be seen that the reason why the lungfish can survive on land for a long time out of the water is because of two important conditions, the first is that it can breathe oxygen, and the second is that the enveloped "cocoon" can keep its body moist.
The crucian carp mentioned above does not have either of these things, not only can the crucian carp not breathe on land, but its body cannot be kept moist, and it has been dried in the sun.
Since this is not the case, then what does crucian carp rely on to survive?
Crucian carp is very terrifying vitality
In fact, there is no other reason, that is, the vitality of the crucian carp is very terrifying, which may be an ability that the crucian carp has cultivated in the process of evolution.
In general, no matter what the water, as long as other fish can survive, then crucian carp can be seen, even if it is a newly dug pond, even if the fish are not released, in a few years, crucian carp will appear. This has to do with its ability to adapt to the environment, and it is arguably one of the most successful species on the planet.
In fact, crucian carp can survive for a long time even if they do not eat, or eat a small amount of food. In the past, there was a large water tank in the countryside where some crucian carp were raised, and after a few years of leaving, I still saw crucian carp alive when I returned.
It can survive for more than 5 years by eating some insects that fall into the water, which can also show the tenacious vitality of crucian carp.
But from a scientific point of view, freshwater fish such as crucian carp, carp and grass carp generally die after 3-5 hours after leaving the water because they do not have lungs and cannot breathe oxygen from the air, and can only breathe oxygen in the water by relying on their gills.
Then they must have a time limit when they are on land, that is, there is always a limit for organisms to leave the environment where they can breathe oxygen, just like mammals in water, after exceeding the time limit, they will die of lack of oxygen.
Therefore, the previous netizen went from catching crucian carp to going home in about 2 hours, which is within the time range when crucian carp is hypoxic but can survive.
Then, one thing is for sure, that is, the netizen who picked up the dried fish at the beginning, from the time the fish left the water to the time he saw the fish, it would not take more than 5 hours, otherwise, the fish will die due to lack of oxygen, and it will really become a dried fish.
With this prerequisite, in the summer, or when the sun is strong, although the surface of the crucian carp is dried, the internal water loss is not as fast as the skin due to the protection of the scales and skin, that is, the internal organs of the crucian carp are actually still sufficient, and they are not as dry as they appear on the surface.
In this case, when the crucian carp, which appears to be a dried fish, is released into the water, its skin quickly absorbs water, and it can also breathe oxygen, so it comes back to life.
In fact, none of the crucian carp died, but the sight of it was like dried fish, which made people misunderstand.
