With 70 percent of the Earth's surface covered by seawater, it's safe to say that the diversity of marine life is nothing less than that of land. There are a thousand strange creatures living in the ocean, among which there is an amazingly large and unique-looking fish that has been noticed by people? The cartwheeling fish.

A wildlife photographer, Herman Herrmann, captured a surprising scene when he was scuba diving, where an overturned fish was being chased by a seal, which had bitten off a large portion of its body, but the fish took it in stride? It's not panicking or panicking at all. s body has been bitten off by a seal, but the fish is not panicking or running away. Does the cartwheeler fish have no sense of pain?

The cartwheel fish, also known as the cartwheel triggerfish, has many nicknames in other countries, such as headfish, sunfish, moonfish, is an oceanic fish.

The shape of the fish is very strange; it is tall, but short and flat, and when viewed from the side, it is oval, yet when viewed from the front or from the top, it is flat.

According to the relevant research, the body size of the car turner fish is large, if the royal ribbon fish is the longest known bony fish, then the car turner fish is undoubtedly the largest bony fish, the body length of the largest can be more than 5 meters, the weight of the adult can be up to 3 tons or so, is widely distributed in the tropical and subtropical oceans, and temperate zone, frigid zone oceans and the coast of China also have their figure, belongs to the large bony fish!

While the rollover fish are huge, they are not vicious creatures, whose main food is some small fish and shrimp, and occasionally eat some jellyfish as a ? snacks?

The reason why they are named cartwheel fish is because they will often float to the surface of the water to bask in the sun, and while they are comfortably enjoying their sunbathing, they also like to turn their flattened bodies upwards and flip them like a waterwheel in the waves, just like turning over a car, which is why they are called cartwheel fish.

Overturned is not a good word, originally meaning a vehicle overturned in an accident, but it has also been used as a metaphor for things not going well or failing. And if it can be applied to a fish, then it can only mean that the fish is no ordinary wreck.

The skin of the rollover fish is very thick, there is no distribution of nerve endings inside, and is eaten by other creatures are generally its thick skin, so they do not feel the pain, in the network is also rumored to have a number of rollover fish cause of death.

Looking at it will make people laugh and spray, for example, some of the rollover fish is due to excessive tension and death, and some because lying on the surface of the sea can not be turned over, was alive in the sun, and so on, can be said to use ? The stupid big one? to describe the rollover fish is very apt!

Because of the huge size of the turnover fish, tail fin degradation, so the turnover fish in the sea action is relatively clumsy, reaction is also relatively slow, and swimming speed is also extremely slow, almost can't swim, said out all let a person incredibly, the fish is not good at swimming!

That's why they are often targeted by other predators, such as sharks, killer whales, or sea lions, seals, and even tuna, which prey on them.

Throughout the marine life world, carnivorous sea creatures bully the flippers because it's the flippers that are weak in both offense and defense. But incredibly, the dumb and stupid tilapia is not yet extinct.

First of all, and this is the most important point, thanks to the powerful reproduction ability of the tilapia, the tilapia spawns a large number of eggs at a time, according to biologists, an adult female tilapia can be discharged at a time of 0.25-300 million eggs, the spawning champion of the vertebrates.

While the hatch rate of the eggs isn't very high, with probably only one in a few million surviving to the end, the large enough base ensures that the population won't be culled due to lack of viability.

Secondly, the turncoat has a thick skin, and although its body has been partially eaten by other creatures, there is still a chance that it can survive. It is common to see images on the Internet of turncoats with their bodies gnawed on but still roaming the oceans, and that has something to do with its thick skin as well.

In this case, the rollover fish is either nibbled to death all the time, or after its body is partially eaten, the predator eats its fill and leaves, and the rollover fish continues to live.

Finally, humans, as the supreme ruler of the food chain, no matter what animal, the biggest natural enemy should be humans, and the cartwheeler fish often go to the surface of the sea to sunbathe, so it is very good to catch, but the cartwheeler fish can be eaten, but it's not very tasty, so humans don't prey much on the cartwheeler fish.

The cartwheeler fish can be described as an oddity in the biological world, utilizing its high birth rate to ensure the reproduction of its own offspring, but in general, no matter what the reason is, any creature as long as it is able to survive, that is a kind of victory.
