Question

Describe the mechanism of swimming in fish.ng in fish.

Answer 1

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.

Explanation:

Answer 2

• Fins, body muscles, and the tail of fishes are used to propel them around.
• The fish's body is designed to allow it to swim. They have a scale-covered, streamlined spindle-shaped body.
• This body form creates the least amount of resistance to water movement, making swimming simpler.
• The backbone is flexible, and its skeleton is made up of thin bones.
• The front section of the body curves to one side while swimming, while the tail curves to the other.
• Then it abruptly reverses direction.
• This causes a shock in the body and propels it forward.
• It's done again if you want to go forward.
