Explanation:

Hydrophytic adaptations help aquatic animals to survive and live under the water. The term hydrophytic adaptation is used with respect to aquatic plants adapted to survive in an aquatic environment.

Whereas, fishes are primarily aquatic animals. Rohu, Labeo rohita, is a freshwater fish. Largely reared for food.

Like all other fishes it has various adaptations to live underwater:

• Paired and unpaired fins help them swim underwater.
• The body structure is tapering at both the ends and broad towards the centre enabling them to swim through water resistance efficiently.
• Gills, supplied with capillaries helps acquire the oxygen from the water and release the carbon dioxide into the water.
• The thin skin is covered with a mucous layer which provides protection and also helps to retain moisture.
• Scales help in the locomotion and provide protection.
• The swim bladder is a gas-filled organ that helps them to stay at the desired depth without the input of energy.
• Lateral sense organs unique to fishes help them sense the water current, vibrations and water movement.
