The Amazon River has always been a gathering place for animals, and there are few residents. And this place also produced a lot of lethal animals. Injuries to the Amazon River are not uncommon every year. Some people even list the Amazon River killer list, each fierce and brutal, can directly cut off your life, let's take a look at a kind of catfish. So why is the catfish?
This fish is full of needles, usually needles are flat on the body, when there is danger it immediately rushes to the surface of the water, swallows the air in a big mouth, so that the body expands into a round ball, and the needles of the whole body are also erected in all directions, at this time, its abdomen lies on its back in the water, and part of the body is exposed to the water, so that up and down can defend against the enemy's halberd, after the danger has passed, it will release the air in the stomach, and the body will return to its original state.

The catfish is good at using its sharp spines, and once it is targeted by the piranha, it swims as fast as it can to the bottom of the piranha's belly, and no matter how the piranha swims, it moves in sync with it. If the piranha wants to bite it, the catfish immediately spines and spines, making the piranha helpless and becoming the natural enemy of the piranha.
Catfish are found in the Amazon and Orinoco river basins of Peru, Brazil, Colombia and Guyana in South America. The catfish is good at using its sharp spines, and once it is targeted by the piranha, the catfish swims as fast as it can to the bottom of the piranha's abdomen, and no matter how the piranha swims, it moves in sync with it.
<h1 class="pgc-h-arrow-right" data-track="6" > catfish is number one on the Amazon River Killers list</h1>
The reason why the catfish will rank first in the Amazon River killer list is because it has a strong lethality and defense, its figure is almost all over the rivers in Brazil, Peru and other countries in South America, the catfish swim very fast, even if it encounters a piranha, it can quickly swim to the bottom of the piranha's abdomen, began to synchronize with the piranha, in order to prevent itself from being discovered.
And when the piranha is found, it can quickly open the long spines on its back and directly pierce the piranha, and like the pufferfish, it will bulge its body in times of danger, and the long thorn-like spines all over the body will stand up, so that no enemy from that direction can bite it, but will be afraid of its approach, until the end of the battle, it will release the air in its stomach and restore its flexible free body.
The reason why the piranha is not as good as the catfish is because the piranha only has the advantage of the group and its sharp teeth, and there is no protection on the body, so the catfish can pose a threat to the piranha, but the piranha cannot bite the catfish. It is estimated that only the most electrically discharged electric eel in the Amazon River can compete with the catfish, after all, the electric eel was once known as the high-voltage line in the water.
Probably many people think that piranhas can't sneak attack catfish?
Wouldn't it be okay to bite the catfish without opening its spines? In fact, this is really very difficult to do in the turbid waters of the Amazon River, it is said that piranhas need to be at least within 25 centimeters of their prey to see before launching an attack, and piranhas do not swim as fast as catfish, so catfish vs piranhas will mostly win, which may also be one of the reasons why catfish are at the top of the list.
