Question

what has fishes to move in forward direction except shape​

Answer 1

${\huge{\underline{\underline{\bf{\red{Answer}}}}}}$

The locomotion in fishes is because of their fins, body muscles and tail. The body of the fish is adapted for swimming in water. They have a streamlined, spindle-shaped body which is covered with scales. This body structure offers the least resistance to the flow of water and makes them swim easier. Their skeleton is made up of thin bones with the flexible backbone.
