New study first to document the voices of fish larvae

A new study from researchers at the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science is the first to document that fish larvae produce sound. These "knock" and "growl" sounds may help small larvae maintain group cohesion in the dark.

"Although many adult fishes produce sounds, no one has previously considered that larvae, too, may be sound producers. This is the first study to show that fish larvae have an acoustic repertoire," said Claire Paris, UM Rosenstiel School associate professor of ocean sciences. "This is a true discovery as it reveals the existence of a communication system for young fish larvae."
