Do all aquatic animals breathe oxygen dissolved in water ? Explain?

Answered by admin @ 20/08/2021

Thanks for asking the question.
No, not all aquatic mammals breathe oxygen dissolved in the water. Some aquatic animals such as dolphins come to the surface of the water to breathe the oxygen present in the air. Only those aquatic animals breathe through the oxygen dissolved in water which have gills modified for gaseous exchange.
Hope it helps.
