Question

Mention the adaptations in fishes which make them aquatic.

Answer 1

Adaptations in fishes that make them aquatic are as follows: -

1. They have gills that allow them to “breathe” oxygen in the water.
2. They have a streamlined body which reduces water resistance and helps them to move easily and faster in water.
3. Most fishes have several fins for swimming, stability, balance and steering.
4. They have a system of muscles for movement.
5. Most fishes have a swim bladder that allows them to maintain buoyancy.
