Question

Which part/parts of a fish help in bringing about movement?

• A. Fins
• B. Tail
• C. Both A and B
• D. None of these

Answer 1

The correct option is C Both A and B

• The skeleton of the fish is covered with strong muscles.
• During swimming, muscles make the front part of the body curve to one side and the tail part swings towards the opposite side. The fish forms a curve.
• Then, quickly, the body and tail curve to the other side.
• This makes a jerk and pushes the body forward. A series of such jerks make the fish swim ahead. This is helped by the fins of the tail.

Hence the correct option is C.
