because they have gills that extract oxygen from the water, much like land animals have lungs that extract oxygen from the air.

Gills function similar to our lungs but only operate properly in the water. They extract the oxygen from the water instead of from the air. Some fish have what is known as a labybrinth organ which allows them to breathe air like we do, such as the betta splendens or the common two spot gourami. These fish can often be seen going to the top of the water surface to "gulp" the air. These fish have adapted to water conditions with a low oxygen rate.

Gills enable a fish to take in water and remove the oxygen within, and the process just repeats itself.

ask a vet, and quit with the stupid questions already.
Fish are not made to be like u and me. They have to breath the water and we have to breath the oxygen.

The fish has, as you know, gills.........amazingly water is filtered back to the lake and the air is sent on through the fishes lungs. I'd like that.............I would never fear drowning......
