Why does the rate of breathing in aquatic animals is faster than other

1.	Why does the rate of breathing in aquatic animals is faster than other?
Answer» Because there is a lack of oxygen in water as compared to us. So, breathing rate is faster in acquatic animals as compared to us. Aquatic animals breathe at a faster rate than the terrestrial animals because the amount of dissolved oxygen in water is fairly low compared to the amount of oxygen in the air. To meet the oxygen need aquatic animals breathe faster to intake more oxygen.
