Question

Name the adaptation of fish which helps it in swimming in water

Answer 1

Streamlined body shape and fins helps the fish to swim in water.Fish has developed special structures called gills which absorb the dissolved oxygen in water.

Answer 2

Fishes consume water and this water is expelled through the gills, but not before dissolved oxygen is extracted from it. The gills are specialized organs and are full of blood vessels. As the water is pushed out of fish's body (through gills), the dissolved oxygen mixes with the blood. And that is how fishes manage to get oxygen while living underwater.....
