Question

How do fish swim in the water..??? Do they have special energy??

Answer 1

Answer:

Many fish swim using an undulating motion of their bodies. The muscle activity that bends the body and produces these movements during steady, continuous swimming can cost a significant amount of energy. ... The pattern of muscle activity along the body also changes, where only muscles close to the head are active.

Answer 2

Answer:

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.
