This series of small bones links the swim bladder to the inner ear in Ostariophysian fish, including minnows, carp, catfishes, and characins. When a sound wave hits the swim bladder, the vibration is transferred through the Weberian apparatus to the auditory region of the inner ear. This action helps amplify sound and, as a result, these fish have very sensitive hearing and can hear sounds that many other fish are in capable of hearing.
