Why do flounder eyes grow on one side? Flounder, also known as flounder, is very flat and oval, and the largest flounder can reach 5 meters in length. In fact, when flounder was a child, its eyes still grew on both sides, and like ordinary fish, it lived in shallow water. However, after about 20 days of growth, it grows to about 3 cm, and one eye on the head will continue to approach the other over the top of the head until adulthood.
The reason why the eyes of flounder can move freely in the head is because the head of flounder is made of cartilage. When the eyes move, the cartilage between the eyes is absorbed by the body, so there is no obstacle. Adult flounders are no longer suitable for floating on the sea surface, so they usually sink to the bottom of the sea, disguise themselves with sand and catch prey.
At this time, the benefits of having two eyes on one side are reflected. When the flounder is ready to hunt, it will bury its whole body in the sand, showing only two eyes. When the prey approaches, two eyes can help it observe the prey better, so this is also the result of natural evolution, just like why the neck of Changjin deer is so long.
Why doesn't the flounder eat its own body? The flounder is a deep-sea flounder. Because its meat is delicious, it is often cooked as delicious. In fact, the body parts of flounder can be eaten. It is very popular to make sashimi by scraping bones in the United States, Japan and other countries, but these countries don't like to eat fish heads, so they sell them to China in large quantities at low prices. Later, we always saw the head of the flounder being cooked, but we couldn't see the body parts of the flounder.
Moreover, the price of sole head is more expensive than that of vegetable head, but the personal taste is different. Some people think that plaice head is common in meat, but it is good for health, not only contains a certain amount of calcium, but also Japanese nutritionists have found that fish head contains more unsaturated fatty acids than any other food, which is very good for brain development.
Flounder not only looks strange, but also, like chameleon, is one of the top ten mysterious color-changing animals in the world, with very good camouflage technology.
