Larval corals drifting in the plankton find their way to safe settlement spots on coral reefs in their first days as free-swimming larvae by listening to the noise of animals on the reef and actively moving toward it, an international team of researchers working in the Caribbean has discovered.

These findings may prove useful as pressures to those who wish to aquaculture stony corals via sexual reproduction, but they also raise new concerns for the future of coral reefs as increasing human noise pollution in the world’s oceans can mask reef sounds.
