The reason why fish die out of water is that they breathe with their gills. When water flows through the gill filaments, they can get oxygen. In the air, the gills cannot play a role, causing them to suffocate and die. However, there are some deep-sea fish, which are suitable for the water pressure at the bottom of the sea, will die because they do not adapt to the air pressure after leaving the water.
1. African lungfish: There is a special fish in Africa, called African lungfish. This fish lives in fresh water, but the local environment is special, and it will experience a dry season, when the river will dry up. When there is no water in the river bed, the fish will aestivate in the mud and live for several months until they come back to water.
2. Mudskippers: Mudskippers are fish that have always been used to inhabit estuaries, harbors, and shallow water areas. This kind of fish will go to the beach to feed at low tide. Their developed pectoral muscle handles can allow them to crawl or jump on land. At the same time, they can also breathe through the skin and oral mucosa, so they can survive for a period of time even after leaving the water.
3. Misgurnus anguillicaudatus: Misgurnus anguillicaudatus is a fish of the loach genus of the loach family. This kind of fish mostly lives at the bottom of rivers, lakes, and paddy fields. It usually comes out at night during the day. It has strong adaptability. And it can use intestinal breathing, when the water dries up, can drill into the soil, as long as there is a small amount of water in the mud, can keep wet, it will not die.
