Coral Reefs' Acoustic Importance
- Coral reefs are highly acoustically diverse and loud underwater ecosystems.
- Their sounds help larval fish and coral locate and settle in healthy reef areas.
Underwater Sound Travels Far
- Underwater sound travels five times faster and further than in air, aiding fish communication.
- Sound enables fish to stay safe by maintaining contact when visibility is limited.
Coral Reef Dawn Chorus Observed
- Isla observed tiny coral reef fish making whooping sounds and synchronizing movements.
- Reefs have a dawn chorus where creatures leave shelter to vocalize and communicate.
