ABSTRACT - CAP 1 - Sound production is used by severa1 animal groups to provide information about an individual (i.e. a sender). However, fishes developed a myriad of sound production mechanisms, and the use of such acoustic signals has already been reported for many species within the context of mate choice, including seahorses (genus Hippocampus). The aim of this study is to verify weather females of the longsnout seahorse (Hippocampus reid) present a positive phonotaxis to the accoustical signals of an intraspecific male. We conducted playback experiments, in which two types of sound were provided to the females: a control and a stimulus. We recorded a total of 9000 seconds in the experiment, and for the analysis, we considered 7200s that females were active. The tested females did not demonstrate positive phonotaxis to the courtship click, and no playback effect was observed in the female during the time that t was into the stimulus zone (Kruskal-Wallis = 4.1272, p>0.05). Our results indicate that the acoustic signal (courtship click) alone was not enough to attract the female. We highlight the need to consider others modalities of communication in future studies, addressing the possibility ability of H. reidi to using the multimodal signalling system in the context of sexual selection.
