How Do Fish Muscles Function in Swimming?
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. Fish use their back fin, called the caudal fin, to help push them through the water. The fish's other fins help it steer.

Keeping this in view, what makes a fish swim fast?

A fish swims by moving its tail (caudal fin) side to side. While each motion provides thrust and lift, it also creates drag when the fin is angled to the side of the body as a stroke is completed. It takes more than a fin to be fast. More tail area gives more thrust, so fast fish have longer lobes on their fins.

Similarly, what is the role of Myotome in the locomotion of fish? Fish swimming: patterns in muscle function. Undulatory swimming in fish is powered by the segmental body musculature of the myotomes. Power generated by this muscle and the interactions between the fish and the water generate a backward-travelling wave of lateral displacement of the body and caudal fin.

Also Know, how do fish survive in the water?

Fish do not breathe air. They get the oxygen they need from the water they live in. Fish have special filters in the sides of their body called 'gills' that act as their 'lungs'. The fish opens its mouth to let water flow through the gills and out of its body.

Which parts of the body helps fishes to breathe and swim?

Gills

Can a fish survive in milk?

Of course fish can swim in milk. It's a liquid with a similar viscosity to water. In fact, just like humans, milk is mostly water. The other problem is that fish aren't evolved to survive in milk so I suspect that they'd quickly catch different bacterial infections that they'd have no defence for.

Do fishes cry?

As for the emotional aspect of crying, i.e., governed by the cerebral cortex and limbic system which the Central nervous system of fish lacks- another reason why, they cannot cry. But scientists have discovered a fish that can cry, just vocally though. No tears whatsoever!
