Why do flounder eyes only grow on one side?

The fact that the two eyes of the flounder grow on one side of their body is actually the result of their constant adaptation to their living environment. Actually, the little flounder that has just hatched also has eyes on the sides of its body. When they grow to about 1 centimeter, the development of various parts of the body begins to become unbalanced, so they begin to lie on their side on the bottom of the sea.

At this point, the eye on the lower side of them begins to gradually move upwards, passing through their backs to the upper one, and is next to the upper eye. Flounders have two eyes on one side, which is extremely beneficial for them to spot predators and catch food, which is also not found in other fish. It is also called a rex fish, a tama.

It is found in tropical to cold waters. <>

In ancient times, people thought that flounder was a male and a female swimming side by side, like a husband and wife walking side by side, so there was a good saying "phoenix bird amphibious flounder". Why do flounder eyes grow on the same side?

In fact, flounder is no different from other fish when it is born, and the eyes are also evenly grown on both sides of the head, and each side is symmetrically distributed.

But after a while, about 20 days or so, the shape of the flounder began to change. When his body grew to 1 cm, his eyes began to move to the side. The path of the eye movement of the fish is through the upper element of the head, and then slowly move to the opposite side, until it is close to the other eye.

The skull of the fish is different from other animals, it is not a hard bone but a cartilage. When the eyes of the flounder begin to move, the cartilage of those eyes will be absorbed by the body first, and with the introduction of the novice cartilage, the movement will lose the barrier, and the movement will be more free.

This change is actually the result of natural selection and its own evolution. Flounders generally swim sideways or even swim, and they often lie flat on the bottom of the sea, covered with a layer of sand. In order to be able to spot enemies faster, it is best to have two eyes together.

Unique locations are not innate, but acquired, changing according to the environment and the needs of survival.

Flounders live on the bottom of the sea all year round, lying flat underwater for a long time, and the eyes on the lower side are useless at all. Therefore, its eyes are all long on one side, which is very good for spotting predators. This is the result of long-term adaptation of flounders to the environment.

This is due to the secretion of the thyroid gland during the growth of flounder.

That's because than bathing for a long time in the dark environment to grow, flounder often leaning on one side no. A wide place to live. So over time, the genetic mutation produces such a phenomenon, and the flounder grows on the same side of the eye.

Why do you say that the eyes of flounder grow on the same side? If it doesn't grow on the same side, it's not called a flounder.,He's going to ask for another fish.,Because it's on the same side.,That's why he's called flounder.,It's late for the origin of the screen and.。

Flounder's eyes must be on the same side, which is natural. It's like the nitrile of a human eye grows on both sides. If the eyes of a person grow on the same side, isn't that a deformity? It's the same with animals.

This is the result of evolution. Flounders swim in such a way that it is normal for their eyes to be on one side.

It may be due to environmental factors that make the eyes of the flounder grow to one side.

Flounders have eyes on the sides when they are first born and grow as they grow. The eyes of one side of the fish begin to move closer to the other. Doesn't stop moving until it's close to the other eye.

What does this mean? This has to start with the living habits of flounders. Because flounder has a relatively weak food chain in the ocean.

Therefore, in order not to be discovered and eaten by natural predators, they can only cover their bodies with a layer of sand, and show their eyes to wait for their prey and avoid natural predators, and live in such an environment for a long time. This makes the eyes of the flounder what they are now. This is actually Darwin's theory of evolution.
