Because people breathe with their lungs, and fish breathe with their gills.
In fact, fish, like people, must breathe oxygen to survive, there is oxygen in the air and water, and the human lungs can separate the oxygen in the air but cannot take the oxygen in the water from the bucket ruler, so people can only live on land.
And can't breathe in the water, most fish don't have lungs.
But there are gills that separate oxygen from the water.
So, the fish can breathe oxygen in the water.
There are also some fish, in addition to gills and lungs.
So talk about those fish can live on land for a while.
Some of them can live for a few hours, some for a few days, and some even on land for years.
About the structure of the fish, see the following.
**Illustrate. It's intuitive:
-
Fish belong to the lower animals of vertebrates, and the gills of fish are only adapted to absorb oxygen from the water, but not to the oxygen in the air, so the fish can only live in the water. Fish have gills that help fish absorb oxygen dissolved in the air. The main "swimming tool" of fish is the fin, which is the perfect swimming tool that the fish have evolved over time in the water.
Most of the fish are pointed at the end and wide in the middle, which can effectively reduce the resistance of the water.
Fish live in water because they breathe with their gills, and fish are unable to take in oxygen in the air after they leave the water. Since they have no limbs and cannot adapt to life on land, they are more convenient to swim and hunt in the water. However, there are also some fish that can live out of water for a short time, such as climbing perch, which can breathe in the air with gills, mudskippers who can breathe with **, and African lungfish that can sleep in the mud for months.
Fish have characteristics that are suitable for living in water:
1. The color of the fish's body is dark and shallow, which is the protective color of the fish.
2. The body is streamlined, large in the middle and small at both ends.
3. The surface of the body is covered with scales to protect the body; There is a layer of mucus on the surface of the scales, which reduces the resistance of the water when swimming.
4. There is a row of lateral lines on both sides of the body, which are connected to the nerves, mainly to determine the direction and sense the role of water flow.
5. The body of the fish has pectoral fins, dorsal fins, pelvic fins and caudal fins, which are the locomotor organs of the fish in the water.
6. Fish breathe with gills.
7. There is a swim bladder in the body, the main role is to adjust the specific gravity of the body, and the swim bladder can make the fish stay in different water layers under the coordination of the fins.
It should be no problem.
