Question
How important is the presence of air bladder in Pisces?
Solution
- The swim bladder, also known as the air bladder, is a sac-like protrusion from the dorsal wall of the oesophagus found in bony fish.
- It functions hydrostatically. It keeps them from sinking by controlling their buoyancy and assisting their up-and-down swimming.
- In certain animals, the air bladder aids in breathing as well. It can also make or receive sound waves by acting as a resonating chamber.
