Despite spending weeks at sea as larvae, potentially scattered over many kilometers, young coral reef fish find suitable settlement habitat and in some cases return to their natal reefs. We report that some dominant families of larval reef fish use the sounds made by fish and shrimp resident on reefs to help them locate and settle on reefs and that some fish groups use specific components of the reef sound to guide their behavior. These findings could offer potential for active management of… 
Small-Boat Noise Impacts Natural Settlement Behavior of Coral Reef Fish Larvae.
This study suggests that boat noise, now a common feature of many reefs, can compromise critical settlement behavior of reef fishes.
Juvenile coral reef fish use sound to locate habitats
Results indicate that some juvenile fish use specific habitat sounds to guide their nocturnal movements, and are able to not only use the directional information contained in acoustic cues, but can also interpret the content of the acoustic signals for relevant habitat information which is then used in their decision-making for orientation.
Coral Larvae Move toward Reef Sounds
It is shown that coral larvae respond to acoustic cues that may facilitate detection of habitat from large distances and from upcurrent of preferred settlement locations, which is the first description of an auditory response in the invertebrate phylum Cnidaria, which includes jellyfish, anemones, and hydroids as well as corals.
Soundscape manipulation enhances larval recruitment of a reef-building mollusk
Oyster larval recruitment was significantly higher on larval collectors exposed to oyster reef sounds compared to no-sound controls, providing the first field evidence that soundscape cues may attract the larval settlers of a reef-building estuarine invertebrate.
Oyster Larvae Settle in Response to Habitat-Associated Underwater Sounds
The results suggest that oyster larvae have the ability to respond to sounds indicative of optimal settlement sites, and this is the first evidence that habitat-related differences in estuarine sounds influence the settlement of a mollusk.
Soundscape variation from a larval perspective: the case for habitat-associated sound as a settlement cue for weakly swimming estuarine larvae
A conceptual model is demonstrated with a conceptual model that response to habitat-related sound cues is a feasible mechanism for enhanced larval encounter with settlement substrate.
Boat noise disrupts orientation behaviour in a coral reef fish
Coral reef fish larvae use sound to find suitable habitat during their vital settlement stage. Yet boat noise, which can cause stress and avoidance behaviour, and may cause masking via reduction of
Coral reef fish smell leaves to find island homes
It is hypothesized that clownfish Amphiprion percula use a suite of olfactory stimuli to locate vegetated islands, which may explain the high levels of self-recruitment on island reefs.
From the ocean to a reef habitat: How do the larvae of coral reef fishes find their way home? A state of art on the latest advances
It is hypothesised that as the stability of fish communities is dependent, in part, on the sta- bility of social interactions, the disruption of "larvae-habitat relationships" can have major con- sequences for larval settlement into adult population with further repercussions for the ecosys- tem as a whole.
Adaptive Avoidance of Reef Noise
It is suggested that a far greater range of invertebrate taxa than previously thought can respond to acoustic cues, emphasising yet further the potential negative impact of globally increasing levels of underwater anthropogenic noise.
