The big-beaked, rock-munching fish that protect coral reefs - Mike Gil

Discover the quirky creature known as the parrotfish, and the key role it plays in keeping coral reefs healthy and thriving.

--

As the sun rises over a quiet coral reef, one animal breaks the morning silence. Named for its vibrant scales and beak-like teeth, the parrotfish devours a particularly crunchy breakfast: rocks. Why would any creature take bites out of the seafloor? Mike Gil explores how these quirky and flashy foragers play a key role in defending the essential coral reef ecosystem.
