Wierd thought.... Do fish cry?

While animals do not cry in the way that humans do, they do produce tears. Since tear production, called lachrimation, is necessary for healthy eyes, most vertebrates are capable of producing tears. Tears are produced in mammals by the lachrymal system, tissues which make water. In land mammals, tears evolved to replace the water bath that the eyes of aquatic animals and fish are constantly surrounded by. Tears serve to clean the cornea and keep it moist. When a speck of dirt, for example, is lodged in the eye, more tears are produced in order to wash away the irritant. The fluid in tears is rich in nutrients and has anti-bacterial properties which help to fight infections. The salt in tears helps to create an osmotic balance within the eye. In animals, it is virtually impossible to tell if their tears are the result of emotions or merely caused by eye irritation. Most scientists agree, however, that humans are the only animals who produce emotional tears. While animals may not weep like humans, they do, however, emit cries which seem to indicate emotional distress. Baby animals of all kinds will vocalize when separated from their mothers. Baby elephants in particular produce a very sad, keening sound which sounds like weeping. Hunters and some wildlife experts have claimed that the sound of a bear cub cries, when separated from its mother is remarkably similar to the cries of a human baby. In these cases, the cries probably serve as a form of direct communication with the mother.

i dont know if they cry.i think animals feel emotions like we do but im not sure about fish,they look a bit dumb but who knows?

Fish can't feel pain, but they react to stress, "Fish cry out in both pain and fear. According to marine biologist Michael Fine, most sound-producing fishes 'vocalize' when prodded, held or chased. In experiments by William Tavolga, toadfish grunted when electrically shocked. What's more, they soon came to grunt at the mere sight of an electrode."

I don't see where that could be physically possible, emotionally either because I don't think that they remember long enough to be sad? Best I could do.

Ive never seen tears or heard a cry when cutting their heads off

Humans cry due to emotions, dry eyes, or foreign elements in the eye. Due to fish being in water, dehydration is not an issue, nor do fish have to worry about dust or smoke in their eyes. As for crying outside of water...fish do not have eyelids because in their element they would not dehyrdate, thus fish would not be able to push out water from their eyes and have not deveolped tears ducts because they were neveer necessary.

I dont think fish cry, they do sleep with their eyes open though, they may have feelings, but no tear drops from eye, since crying means water drops from eyes
