The rollover fish is really an oddball, born especially small, and there is no protection ability, even after growing up, there is no life-saving ability, but in the weak and strong in the ocean has not been extinct, is really very strange, many animals, although there is no attack, but there is indeed a means of self-preservation, such as antelopes, can climb to the cliffs, monkeys can climb the tree, the ordinary fish swim fast, these are some specialties, so basically will not go extinct, but no such specialties. These are a bit of specialties, so basically will not go extinct, but the rollover fish in fact and these are not related to these, not these specialties, the reason why there is no extinction, because it has other aspects of the characteristics

1, breeding ability

The rollover fish reproduction ability is particularly strong, an adult rollover fish has three meters long, a spawning can be spawned about three hundred million, the number is simply horrifying. Terrifying, but from birth to adulthood, so many turnover fish, only a few dozen can grow to adulthood, it can be said, the reason why there is no extinction, and the ability to spawn is very much related. That base is too large. There's also the fact that the baby turnover fish will grow a ring of spines on their body, kind of like a puffer fish, so it's also a way to avoid some predation.

2, the viscera of the turntable fish have some toxicity

Some scientists have done some tests on the viscera of the turntable fish and found that their viscera have a lot of toxins, these toxins and puffer fish in the body of the same toxins, this is because the turntable fish will eat a kind of four-toothed leatherbacks, leatherbacks in the body of a large number of tetrodotoxin, so eat a lot of, the turntable fish body contains a lot of these toxins. Tetrodotoxin. That's why many predators don't eat this poisonous food.

3, the turntable fish skin is very thick

The turntable fish has no attack ability, swim up also very slow, no escape ability, but its skin is very thick, there are seven centimeters so thick. This defense is very strong. In addition to some large predators with very long teeth, general fish is very difficult to bite through the skin of the car flipper, but the kind of large sharks, killer whales and not to the car flipper as the main food, so the car flipper is relatively speaking still have a certain degree of safety and security.

It is because of these several reasons, let the turnover fish although very bulky, but still not extinct.
