Summary
This study recorded and analyzed vocalizations of green sea turtles (Chelonia mydas) off the Caribbean island of Martinique, and identified which sounds seemed to be linked to flight, fear, and social aspects. When these recordings of sea turtles were played to wild sea turtles, they demonstrated behavioral responses (vigilance and/or escape) to the sounds they produce, suggesting that acoustic deterrents may be effective to reduce sea turtle bycatch. Sea turtles did not respond to synthetic or geophonic noises.
