... Gobiidae sonic mechanism sonic muscle grunt tonal call Fishes have evolved the largest diversity of sound-generating mechanisms for acoustical communication among vertebrates ( Myrberg and Lugli, 2006 ). However, there exists no commonly accepted classification, mainly because various taxa...

... are generated by rapid contractions of sonic muscles that insert on a broad tendon surrounding ventrally the cranial sac of the swimbladder. The piranha swimbladder is thought to play an important role in sound production as an impedance-matching device and as a resonator. However, the vibratory capacities...

... with a complex swimbladder mechanism, including skeletal components and extrinsic sonic muscle fibers with an exceptional helical myofibrillar structure. To study this system we stimulated the sonic muscles, described their insertion and action and generated sounds by slowly pulling the sonic muscles. We find...

...Martin A. Connaughton SUMMARY The Northern searobin ( Prionotus carolinus ) contracts its paired sonic muscles alternately rather than simultaneously during sound production. This study describes this phenomenon and examines its effect on sound production by recording sound and EMGs during...
