Expanded Information:

< p>The growth of the swim bladder follows the growth of the fish body until the body stops growing and so does the swim bladder. Its shape is determined by the shape of the fish's body and the spatial structure of the abdominal cavity, allowing buoyancy to be generated at various points of the fish's body to counteract the gravity generated in different parts.

The swim bladder has the following three main functions:

Firstly, it aids in the lifting and lowering of the fish in the water, and is also used as a stabilizer, being located in the center of the fish's body, which keeps the center of gravity down.

Secondly, it creates enough space in the fish's abdominal cavity to protect its internal organs and prevent them from being damaged by excessive water pressure.

Thirdly, the swim bladder can be used as an auxiliary respiratory organ in lungfish and total finfish.

Fourth, the swim bladder can be used as a ****ing chamber to produce or receive sound.

Fifth, the swim bladder can be used as an auxiliary respiratory organ to provide oxygen to the fish in an oxygen-deficient environment.
