In fish like catfish and minnows, the swim bladder is connected to the inner ear by a special set of bones called Weberian ossicles. This physical connection allows a greater range and probably also more sensitive hearing.
The gas-filled swim bladder, which is more compliant to vibration than the fish's body, senses the pressure difference caused by the sound wave; its motion is transferred via bones called the Weberian ossicles to the inner ear.
