Caption: A new study led by Dr. Claire Paris, professor at the University of Miami Rosenstiel School of Marine & Atmospheric Science conducted at One Tree Island in the Great Barrier Reef used an o-DISC (ocean Drifting In Situ Chamber,) a unique device created in Paris' laboratory that is composed of circular behavioral arena transparent to light, sound and small scale turbulence, to track a single fish larva. The o-DISC was set adrift in the water column and the swimming activity and bearing of the larva was recorded using an underwater motion sensing and imaging system. The team established that reef fish larvae can smell the presence of coral reefs from as far as several kilometers offshore, and use this odor to find home.
