And when they go silent, the whole ecosystem suffers.
Here’s the wild part:
Scientists discovered that by playing the sounds of healthy reefs on underwater speakers, they can lure fish and coral larvae back to damaged reefs.
The results?
➡️ Coral exposed to reef sounds settled 70% more often
➡️ In some sites, settlement increased by 700%
Why it works:
Healthy reefs buzz with life, crackling shrimp, grazing parrotfish, darting reef dwellers. Young coral and fish hear those signals and move in. Dead reefs are quiet. By recreating that soundscape, we’re tricking life into returning.
It’s a simple fix with massive potential.
Because in just 30 years, we’ve lost 25% of coral reefs worldwide.
And without them, entire marine ecosystems collapse.
Sometimes, the most powerful innovations aren
