  abstract = {{A}lthough the primary function of the swim bladder is buoyancy, it is also involved in hearing, and it can be associated with sonic muscles for voluntary sound production. {T}he use of the swim bladder and associated muscles in sound production could be an exaptation since this is not its first function. {W}e however lack models showing that the same muscles can be used in both movement and sound production. {I}n this study, we investigate the functions of the muscles associated with the swim bladder in different {P}teroinae (lionfish) species. {O}ur results indicate that {P}terois volitans, {P}. radiata and {D}endrochirus zebra are able to produce long low-frequency hums when disturbed. {T}he deliberate movements of the fin spines during sound production suggest that these sounds may serve as aposematic signals. {I}n {P}. volitans and {P}. radiata, hums can be punctuated by intermittent louder pulses called knocks. {A}nalysis of sonic features, morphology, electromyography and histology strongly suggest that these sounds are most likely produced by muscles closely associated with the swim bladder. {T}hese muscles originate from the neurocranium and insert on the posterior part of the swim bladder. {A}dditionally, cineradiography supports the hypothesis that these same muscles are involved in altering the swim bladder's length and angle, thereby influencing the pitch of the fish body and participating in manoeuvring and locomotion movements. {F}ast contraction of the muscle should be related to sound production whereas sustained contractions allows modifications in swim bladder shape and body pitch.},
