 Directional orientation of pomacentrid larvae to ambient reef sound.
 Coral Reefs, 23(2), 184 - 191
 Abstract: The mechanisms by which reef fish larvae locate settlement
 habitat at the end of their pelagic phase are unclear. We used an in
 situ binary choice chamber and an artificial source of reef sound to
 determine whether pomacentrid larvae can use ambient sound to locate
 reefs. Larvae were caught in light traps and then placed in a submerged
 binary choice chamber with an artificial source of reef sound ~80 m from
 one end of the chamber. At night, larvae moved towards the sound source;
 during the day, larvae showed no preference. These results suggest that
 pomacentrid larvae can detect reef sound and are capable of directional
 hearing. While other studies have shown that reef fish larvae respond to
 reef sound, and that the adults of some species can localize underwater
 sound sources, the localization of underwater sound by fish larvae has
 not been demonstrated previously.
