Fish die out of water because they need to breathe in water. Once out of water, the gill filaments stick together, which reduces the breathing area, causing it to be unable to absorb enough oxygen, leading to suffocation. In addition, some deep-sea fish are adapted to high water pressure, and once they are separated from that water pressure environment, they will also die.
1. Lungfish: Lungfish live on the African continent. Due to the special local climate, rivers have a dry season, when they will completely dry up, and the lungfish in the water must also survive out of water. Its swim bladder is specially constructed to allow it to breathe without being in the water, and it will also drill into the soil and enter a dormant state, which will recover when the rainy season comes.
2. Loach: Loach is also a kind of fish. Its body is cylindrical. It generally lives at the bottom of rivers and lakes. It has strong adaptability. Even if the water is dry, it can survive in the soil, as long as there is a small amount of water to keep wet, it will not die.
3. Mudskippers: Mudskippers generally inhabit coastal areas. When the tide ebbs, they will climb to the shore to hunt for food. The fish can breathe through its skin, so it will not die after leaving the water, but it will return to the water before its body dries.
