Figure 7

Power spectra of male, female, and juvenile sounds in Ophidion rochei. Grey lines: logarithmic power spectra of background noise. Black lines: logarithmic power spectra of (a) a multiple-pulsed sound of male in captivity (smoothed: average over 41 points), (b) a female sound in captivity, (c) a single pulse sound of male in captivity, (d) a juvenile sound in captivity, (e) a multiple-pulsed sound of male in the field (smoothed: average over 41 points), and (f) a female sound in the field. In power spectra that suggested a harmonic pattern (*) the fundamental, (**) the 1st harmonic, and (***) the 2nd harmonic were marked. In other power spectra the two arrows indicate the two main frequencies.
