Muscles are exercised, if exercised enough, the muscles will tear, and be repaired, which is how the body becomes stronger.
After a while of swimming, your muscles use lactic acid. It uses it through Lactic acid fermentation. It results in more energy.
depends on need running for cardio ;heart rate swimming for low impact on joints while building leaner muscles
The pectoral fin on a shark helps with steering and stability while swimming.
The uropods in crayfish function in locomotion by helping to propel the crayfish backward in water. They also aid in steering and stabilizing the crayfish while swimming.

Involuntary muscles are muscles that work without conscious control, such as those in the heart and digestive system. Voluntary muscles are muscles that we can control, like those in our arms and legs. Involuntary muscles function automatically to keep our body working properly, while voluntary muscles allow us to move and perform actions intentionally.
Jawless fishes are voracious feeders while cartilaginous fishes are predators with a various diet.
