“…Producing sound involves a vibration coupled to the medium (Bradbury & Vehrencamp, ). Five basic mechanisms have been documented in teleost communication: (i) muscular vibrations of a membrane or sac (Fine, King, & Cameron, ; Millot, Vandewalle, & Parmentier, ), (ii) stridulation (Bertucci, Ruppé, Wassenbergh, Compère, & Parmentier, ; Fine, King, Friel, Loesser, & Newton, ; Parmentier et al ., ), (iii) forced flow through a small orifice (Fish & Mowbray, ; Lagardère & Ernande, ; Wahlberg & Westerberg, ; Wilson, Batty, & Dill, ), (iv) muscular vibration of appendages (Colleye, Ovidio, Salmon, & Parmentier, ; Ladich, ; Parmentier et al ., ) and (v) percussion on a substrate (Colleye et al ., ). Moreover, although multiple submechanisms have been described, most fall into two categories: (i) muscles that directly or indirectly insert on the swim bladder and (ii) stridulatory mechanisms involving the rubbing of bones.…”
