Detailed Solution

The above statement is true.
All living beings respire. They need oxygen for respiration. The aquatic animals do not have gills. Aquatic species need specialised organs called gills to respire or extract oxygen from water, or they can inhale directly through their skin. The gills are specialised organs in aquatic animals with thousands of blood vessels which extract maximum oxygen dissolved in water. The amount of oxygen dissolved in water is less than in the air. So, aquatic animals breathe faster. Hence, aquatic animals use dissolved oxygen in the water for respiration.
