Sounds appealing – reef recordings entice coral larvae to start building
Scientists have discovered that audio recordings of healthy coral reefs may help attract free-swimming coral larvae to damaged ones. The finding could be a major step toward preserving the world's coral reefs, an estimated 25% of which have died out in the last 30 years.Although the reef structures formed by coral polyps are immobile, the polyps themselves swim through the water while still in their larval state.
