Supporting data: Functional plasticity of the swim bladder as an acoustic organ for communication in a vocal fish

<div> <p>In this study, we show that the swim bladder of male plainfin midshipman fish (<em>Porichthys notatus</em>) exhibits reproductive state-dependent changes in morphology and function for sound production and reception. We quantified swim bladder morphometrics and utilized psuedolandmarking to identify differences in nonreproductive and reproductive male swim bladders. We utilized auditory evoked potential recordings, to measure the auditory sensitivity of saccular hair cells in response to sound pressure levels ranging from 97 - 154 dB re: 1 µPa to determine how the swim bladder contributes to midshipman auditory sensitivity. Finally, we used finite element modeling to explore the frequency response of nonreproductive and reproductive male swim bladders.</p> </div>
