Vibrations of the Weberian apparatus (VIDEO)

University of California - Berkeley

Caption

Juan Liu and her student used finite element analysis to create a computer model of the vibrational response of the Weberian ossicles of fish. This simulation shows the amplitude and vibrations of zebrafish ossicles at a frequency of 1,012 Hertz. The large, triangular ossicle is called the tripus and is a modification of the rib and third vertebra to amplify sound vibrations from the air bladder.
