Do fish really shed tears? How to understand the sadness of the tears of the fish

In fact, tears were originally used to secrete salt, and it seems that only some mammals and some reptiles and birds living in the marine environment have tear ducts. Turtles and seabirds shed tears and dry to leave white salt. Mammals with lacrimal glands also appear to be involved in marine life.

It is even used as a strong evidence that man evolved from sea apes. As for how fish regulate salt in their bodies, the mechanism of marine fish and freshwater fish is different. In the case of freshwater fish, there is no need to remove too much salt from the body.

Even saltwater fish don't rely on tears to drain salt. You can look it up with an animal book, I don't remember exactly. From the evolutionary history of the eyeball, the eyeball of fish is very primitive.

After all, the water environment is not well lit, coupled with the special nature of the water body, so that vision is not the most critical feeling of fish life, and the development of fish eyeballs is also slow. And the human eyeball is very well developed and has sensitive vision. This has a lot to do with the terrestrial environment.

Therefore, in addition to salt discharge, tears have developed the functions of moistening the eyeballs and sterilizing them. Finally, crocodiles are reptiles, which are very different from fish, and there is no need to specifically indicate them, unless people with very weak animal knowledge will confuse them. Many of the things we call "fish" are not fish, such as whales, cuttlefish, squid, and silverfish.

Do fish shed tears? No one can verify it. But the legend that the fish cry has been extended from the Han Le Mansion:

The dry fish weeps across the river, when will they repent and return. Write perch and bream, teach each other carefully. "Perhaps it was then that the fish got lost in the river in which it swam so many times, and the water suddenly decreased, and the fish was stranded.

It wanted to swim, but it couldn't, because the once gentle waves of water had receded, and the once warm sunlight was gone.

No one could see the fish's tears, because it was on the water, its eyes were dry, and its tears were gone.
