Why Do Sharks Die When They Stop Swimming?

Fish have an organ called the swim bladder, which they can use to regulate their depth in the water. However, sharks do not have swim bladders. What's the deal?,First, let's understand the characteristics of sharks:,The skeleton is made entirely of cartilage, the skin is covered with scales (Note: This structure reduces drag, which is why Michael Phelps wore a sharkskin swimsuit and won the gold medal, becoming a hot-selling product),They have exceptional adaptability, keen sense of smell, developed brains, and sharp teeth.

Key point: Because sharks are denser than water, they lack a swim bladder like bony fish, and their caudal fins are not asymmetrical, which negatively impacts their swimming speed, so they can only regulate their position in the ocean by storing fat in their bodies.

However, this is just a buoyancy control method. So why do sharks keep swimming?,Unfortunately, shark gill slits cannot open themselves, they must rely on continuously flowing water to force them open, extracting oxygen from the water. If they stop, the consequences are dire, as they will suffocate without oxygen,If they are caught in a discarded fishing net or injured and unable to swim, they will die!!!

The question is: Do all sharks die if they stop swimming?,Answer: No,Some sharks swim continuously from birth, day or night, whether they are sleeping or awake, until their death. While some sharks, such as the hammerhead shark, lemon shark, and bull shark, can keep their gills in the water and often reside on the seabed, (Although it's a lemon shark, it doesn't really look like one)

(Thinking about being observed by humans, I don't know what I'm thinking!!!)
