Can fishes drown?

Yes, fishes can drown but not in water!

Fishes need oxygen to live. Unlike humans who use the lungs to breathe oxygen, fishes use their gills to breathe under water. The gills absorb life-sustaining oxygen from the hydrogen in the water molecules, in order to regulate the amount of oxygen intake.

When a fish is taken out of water, and exposed only to air, its gills are unable to process and control the oxygen intake.

The gills inhale a lethal overdose of oxygen and the fish essentially experiences death by "drowning."
