Question

How do fins of a fish help in its movements?
please follow​

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.

Answer 2

Explanation:

Fins help fine-tune swimming. The caudal fin, or tail fin, increases speed. The pectoral and pelvic fins steer up or down. They also help fish turn and stop.
