Sound produced yes, active sound production
Type of sound produced knocks, thumps (& croaks)
Sound production organ unspecified but probably swim bladder with drumming muscles in males only & pharyngeal teeth in close proximity to swim bladder in both sexes
Sound mechanism unspecified, but probably similar to Cynoscion regalis: males only: vibration of swim bladder by contraction of associated "drumming" muscles, high-pitched clucking in both sexes produced by stridulation of pharyngeal teeth amplified by swim bladder
Behavioural context under duress (manual & electric stimulation)
Reference Fish, M.P. and W.H. Mowbray, 1970
Remark no sex data available, but lack of croaking in recording suggests female specimen only, since drumming muscles are limited to males in morphologically related sciaenids.Recorded with highpass filter: 60 Hz. Recording amplifed by 6 dB
