We have the impression that fish are generally very "smart" and will swim away quickly as long as there is any wind or grass around them.
But in the ocean, there is a fish that is "not very easy to use", they don't feel the danger at all, they are simply stupid fish.
But stupid fish have the blessing of being stupid, they can lay 300 million eggs in a single production.
However, it is strange that such a fish can be classified as a vulnerable species.
The best "fish" to be born
The sunfish is a large oceanic fish that generally lives in tropical and subtropical oceans, and can also be seen in the East China Sea and the South China Sea on the mainland.
Under normal circumstances, the sunfish weighs 3.5 tons and can reach 5 meters in length, which is about the size of our car.
But newborn sunfish are actually very small, with a body length of only about 2.5 mm, which is almost invisible to the naked eye.
Therefore, if we see what the sunfish looked like when it was a child, it is actually difficult to imagine what it will look like when it grows up.
On the whole, the sunfish is almost oval, with a flat and tall body, eyes that are so small that it is really "not easy" to find, and even the mouth is not in harmony with the overall proportions.
When some scientists studied the shape of the sunfish, they found that such a shape was actually completely contrary to the principles of fluid mechanics, and some people even suspected that the eyes of the sunfish were painted by God to be symmetrical up and down.
And its head and body do not have a very obvious boundary, so it gives people the feeling that there is no body, all are fish heads.
When swimming, the sunfish often floats sideways on the surface of the water, looking like it has overturned, so people call it "sunfish".
Not only that, but sunfish are also very fond of "basking in the sun", and when they are usually idle, they will float on the surface of the water and "soak up the sun".
Because it floats sideways on the water, many people don't think it's a fish at all when they see such a picture, but rather a "water monster".
However, they bask in the sun for the purpose of "sterilization", and there are actually a lot of parasites in the sunfish.
In this way, they will feel itchy from time to time, and they lie on their sides when they are basking in the sun, in fact, it is also for passing birds to help them clean up the "parasites" on their bodies.
In addition to having a special "rollover" ability, in fact, the reproductive ability of the sunfish is the most amazing.
According to relevant information, sunfish can lay more than 300 million eggs at a time, which is really the "ceiling" among all animals.
During the breeding season, male sunfish will find a suitable seabed in advance and use various parts of their body to dig the shape of a large pit.
Pheromones are then emitted to attract female sunfish to spawn.
After receiving the signal, the female sunfish will come to lay eggs, and when they are done, they will leave without looking back, and then leave the male sunfish to discharge sperm and start fertilization.
It can be said that the reproduction process of sunfish is a process of "in vitro fertilization".
After that, the male sunfish will stay in place until their children have successfully grown.
But what makes people wonder why the number of sunfish breeding so many children at one time is not at all, and it is even listed as a vulnerable species?
And this, in fact, is about to talk about the "fancy death" of the sunfish.
The "Swing King" in the Sea
Let's start with the juvenile days of the sunfish.
When the sunfish as a child began to roam freely, their ability to survive was very weak.
The sunfish of this period are not only small in size, but also do not have even the most basic survivability.
It can be said that as long as a big fish comes casually, then the juvenile sunfish will become their "meal".
Even if they survive, if they experience a storm, it is estimated that they will suffer heavy casualties.
Adult sunfish are even more "frightened physique", and will die after a little "wind and waves".
As for the way to die a sunfish, there are actually many more varied.
For example, when basking in the sun, because the sun is too strong, I finally sunburned myself to death, I have to say, this is simply invincible, and when I feel the heat, I won't take the initiative to go back to the sea.
Some sunfish will be scared to death, if it is swimming, a turtle suddenly appears in front of it, then the sunfish will feel that it is about to hit itself, and the next second, it will die because of nervousness and fear.
Even after some sunfish saw their companions die, they couldn't stand such a big blow, and finally "died of depression" directly......
It can be said that every way the sunfish dies is unexpected.
Although these statements are a bit exaggerated, we can also see that the "survival is not easy" for sunfish.
What's even more surprising is that sunfish will not take the initiative to avoid when they encounter danger.
Although the sunfish looks more "tall and mighty", its actual personality is the opposite.
When the sea lion, the natural enemy of the sunfish, will directly bite its back when it preys on them, but the sunfish does not feel it at all, but "floats" alone.
In fact, many people know the sunfish, all through the sunfish being chased and bitten by sea lions, as if the bitten is not themselves.
Because on the surface of the sunfish, there is actually a layer of 7 cm of fish skin, and in this layer of fish skin, there is no nerve at all.
However, the sunfish will also feel pain, but because its own swimming ability is indeed relatively poor, even if it wants to escape, it is weak.
But even so, the sunfish is still not extinct, and behind this, it is also related to some of its own "abilities".
Why didn't it perish?
Although the sunfish is often bitten, it actually has the ability to repair itself.
According to the research of scientists, in the body of the sunfish, a very special substance is actually secreted, and it is this substance that can make the wound of the sunfish heal quickly.
Besides, in fact, there are not many natural enemies of sunfish.
Even if its ability is weak, at least the volume of people is there, and those small fish and shrimp in the sea are impossible to become the "opponents" of the sunfish.
If you think about it carefully, there are only a handful of fish that can hunt sunfish in the sea, which is actually the reason why sunfish is not extinct, after all, it has relatively few natural enemies.
If you have to talk about natural enemies, then humans are also one, but the sunfish is not in people's "recipes" at all, because it is really "very unpalatable" and very susceptible to bacteria.
Not only that, when people are fishing, they are trying to be smooth and smooth, and the name of sunfish is indeed very unlucky.
Therefore, if you catch a sunfish, then the fishermen will release it directly.
Coupled with its own strong prevention ability, although the survival rate is not high, after all, the base is very high, even if it is low, it is not low.
