Through the analysis of acoustic recordings of captive Pterois spp., this study has confirmed anecdotal evidence that Pterois spp. are soniferous. This report of sound production in Pterois spp. provides the foundation for future research into their specific acoustic capabilities including sound production mechanisms, the role of social behaviour and applied techniques for controlling and monitoring invasive Pterois spp. in the tropical and temperate western Atlantic Ocean. REEF staff, Lad Akins, was a co-author.
