Influence of fish size (SL) on acoustic features of submissive sounds in Amphiprion frenatus.

Correlations of (A) dominant frequency, (B) pulse duration, (C) pulse period, (D) number of pulses per sound, (E) sound duration, (F) sound period and (G) number of sounds per train against SL. Fish ranged from 44 to 112 mm in SL (N = 9). Results are expressed as mean values of all recorded pulses for each individual (○ = rank 4, □ = rank 3, ▵ = rank 2).
