Answer:
Fish have the following features that help them in movement.
i) Bodies of fish have a streamlined shape that is narrow at the ends and broader in the middle. This shape minimizes the resistance to flowing water and enables them to move smoothly and quickly through water.
ii) Fins and tails help the fish to swim, change direction and keep the body balanced in the water.
iii) Many fish have a tube-shaped swim bladder or air bladder. This air-filled bladder helps them to stay afloat and adjust the depth under water.
iv) Bodies of fish are covered with a layer of slimy mucus, which reduces friction and aids in swimming.
