Most fish do not sink in water due to the presence of a swim bladder, which is a gas-filled organ located in their abdominal cavity. The swim bladder allows fish to regulate their buoyancy by adjusting the amount of gas (usually oxygen) inside it.
How it Works:
When a fish wants to rise, it increases the gas in the swim bladder, making it more buoyant.
When it wants to sink, it releases gas, reducing buoyancy.
The swim bladder helps fish maintain their position in water without continuously swimming, saving energy.
