Answer:

Explanation:

Fish swim by flexing their bodies and tail back and forth. 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.

The body of the fish is stream-lined, that is, it is long and thin, pointed at both ends. The streamlined body helps the fish to move faster in water. Fish have special structures called fins which help them to move through the water. The tail fin helps the fish to move forward quickly whereas the back fin helps it move in a straight line. The tail of fish is made up of muscles. These muscles contract to move the tail from side to side. The pectoral and pelvic fins occur in pairs. They help the fish when the fish is turning or moving slowly.
