These damselfish produced sounds during six different behaviours and showed three different colour patterns while doing so. These sounds can be grouped into three classes: sounds associated with (1) fighting; (2) mating/visiting and (3) chasing and signal jumps. Moreover, the evolution of the different kinds of sound is discussed: the first calls could be a single pulse originating in teeth snapping. Modifications in the rhythm and number of pulses allowed the fish to build new messages. Daily recordings showed that sound production rates were higher at sunrise and sunset than during the day and that no sound was produced during the night. However, the kinds of call were different: sunrise sounds seemed mainly associated with mating/visiting, whereas the sounds associated with chasing and to signal jumps were mainly found at sunset. specialized 034 157 10 2317-2327 2010 0025-3162 https://www.documentation.ird.fr/hor/fdi:010049084 10.1007/s00227-010-1498-1 0025-3162 [F B010049084] https://www.documentation.ird.fr/hor/fdi:010049084 https://www.documentation.ird.fr/intranet/publi/2010/10/010049084.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2010-11-05 2017-08-23 fdi:010049084 fre
