Question

How can fish move in water?

Answer 1

Fish:

Fish is an aquatic vertebrate in which bones or cartilages (elastic in nature) are present in the body.

The body shape of fish:

1. Fish have a streamlined shape body, in which head and tail ends are smaller than the middle portion (tapered ends).
2. This streamlined shape is such that water can flow around the body easily and allows fish to move easily in the water.
3. Fins are also present in the body which help in movement and balance of the body.
4. Fish also have strong muscles which make the front part of the body curve to one side and the tail fins part swing on the opposite side in the water.
5. This makes a sharp move and pushes the body of the fish forward to swim in the water.
