Everyone knows that a fish pulled out of water suffocates. How can this be explained? because the oxygen content in the atmosphere is much higher than in water.

Animals living in the aquatic environment have respiratory organs that differ significantly from the respiratory systems of terrestrial representatives. Due to the fact that the habitat of fish is aquatic, they acquired special organs – gills, which allow them to receive oxygen from the water. To obtain oxygen, fish must constantly move their gills so that water is constantly driven through them. Therefore, if a fish is taken from its characteristic aquatic environment, it will not be able to breathe, since its respiratory organs are unsuitable for breathing with atmospheric air.
