Fish have gills that allow them to “breathe” oxygen in water. … They are typically long and narrow, which reduces water resistance when they swim. Most fish have several fins for swimming. They use some of their fins to propel themselves through the water and others to steer the body as they swim.
How do fish adapt themselves to live in water?

(2) The fish has special organs called “gills” which-help it to absorb oxygen-dissolved in water for breathing. A fish can live in water only because it is adapted to breathe in water.
Why do fish have this shape 5 points?

Which adoption can help fish to survive in water?
Fishes are adapted to their environment through the evolution of a few special organs e.g. gills, swim bladders and fins. Gills help in absorbing the oxygen present in the water and swim bladders allow to maintains the proper buoyancy level and fins help to move the fish in the water.
What is special about a fish?
As members of the phylum Chordata, fish share certain features with other vertebrates. These features are gill slits at some point in the life cycle, a notochord, or skeletal supporting rod, a dorsal hollow nerve cord, and a tail.
