Underwater ‘doorbell’ helps scientists catch coral-eating fish in Florida

Researchers use innovative cameras to identify fish species hindering coral reef restoration

Marine scientists in Florida working to help reverse a calamitous decades-long decline in coral reefs caught fishy porch pirates" in the act with an innovative underwater doorbell-style surveillance camera.

The footage showed that three corallivorous species - redband parrotfish, foureye butterflyfish and stoplight parrotfish - were responsible for eating more than 97% of coral laid as bait by the researchers at an offshore reef near Miami.
