Question

how do fins of fish help it in swimming?​

Answer 1

Answer:

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 fish's other fins help it steer.

Explanation:

The dorsal and anal fins primarily help fish to not roll over onto their sides. The caudal fin is the main fin for propulsion to move the fish forward. The paired fins assist with steering, stopping and hovering.Fish fins are used to generate thrust and control the subsequent motion.
