Sounds of the Reef

An Ecological Acoustic Recorder (EAR) can record a wide variety of sounds, including whales, dolphins, snapping shrimps, and fishes. Commonly identified fish sounds are produced by the Hawaiian damsel Dascyllus albisella (purr sound), soldierfish Myripristis spp. (drum sound), and butterfly fish Chaetodon spp. This page presents some of the sounds recorded by EARs.
