How does the shape of a fish body help it to move in water?​

Answer 1

Fish stretch or expand their muscles on one side of their body, while relaxing the muscles on the other side. This motion moves them forward through the water. Fish use their back fin, called the caudal fin, to help push them through the water.  Fish have 5 types of fins.
