In trying to determine how these flashy reef fish do so, marine biologist Stephen Simpson, University of York, investigated sound as a possible cue. He and colleague Hong Yang, University of Kentucky, played noises of different frequencies and volumes to fish embryo in a soundproof chamber, and observed them under the microscope. When the sounds were "just right," meaning they matched the pops, bangs, whoops, and crackles emanating from a coral reef, the embryos' heart rate increased.

The researchers confirmed the possibility of acoustical memory on Australia's Lizard Island by creating silent and...
