Baby let me tell you, what fish live in the deepest ocean in the world?

Children, do you know what fish live in the deepest ocean in the world?

The deep-sea alligator lionfish does not have swim bladders

In the deep sea, where the water is more than a few kilometers deep, the sunlight cannot shine at all, and it is a dark world. The water pressure there is extremely high, and there are fewer species of organisms. The deep sea can be regarded as the harshest living environment on earth. However, in such a harsh living environment, there are fish alive. That's the deep-sea alligator lionfish.

The alligator lionfish that live in the deep sea are slightly different from the general fish in the shallow sea. Generally fish have swim bladders, which are used to regulate the buoyancy of the body, so that they can float or dive freely. But there are no swim bladders in the body of the deep-sea alligator lionfish. Kids, when you're swimming, you've all worn swimming rings. The swim bladder has the role of a swimming circle, and the fish control the buoyancy of the body by adjusting the amount of gas in the swim bladder in order to swim in the water.

However, air-filled swim bladders are less practical in the deep sea. Not only is it useless, but it will also be squeezed by high water pressure, so that the fish will die.

You can stay at a certain depth without struggling to swim, how do fish do it?

If the fish do not have swim bladders, in order not to keep the body from sinking, they must keep swimming hard. In the deep sea, where food is very poor, if you keep swimming, the fish will soon be hungry. Coupled with the difficulty of finding food, the fish must not starve to death? However, the deep-sea alligator lionfish live well in the deep sea, how do they do it?

In fact, the secret is hidden in the soft and fat body of the deep-sea alligator lionfish. If the fish are covered with tight muscles, then the density of the body is bound to be relatively large, and it is easy to sink to the bottom. However, the deep-sea alligator lionfish have a relatively low body muscle ratio and look chubby, which allows them to stabilize at a certain depth without effort. This is also an important reason why the deep-sea alligator lionfish can live normally in the deep sea.

Kids, do you want to know the secret of the King Squid?

The King Squid, who lives in the deep sea, also possesses a secret weapon that keeps his body stable at a certain depth. The body of the king squid contains a high concentration of ammonium chloride, which is lighter than water, so the king squid can stay freely in any position in the water.
