Explanation:
- Most bony fish have swim bladders, also known as air bladders, which act as buoyancy organs.
- The swim bladder develops from an opening in the digestive tube and is housed within the body cavity.
- It serves as a hydrostatic, or ballast, organ by containing gas (often oxygen) and allowing the fish to maintain its depth without rising or falling.
- It also functions as a sound-producing or sound-receiving chamber. In some species, oil rather than gas is found in the swim bladder.
In fish, the air bladder serves the following purposes:
- Fish can keep their depth without rising or sinking with its assistance. It aids in keeping buoyancy.
- The air bladder facilitates gas exchange.
- The air bladder functions as a resonating chamber for sound transmission or reception.
