Moray eels thrive on coral reefs close to people


Coral reefs that are in close proximity to larger populations of people tend to have fewer sharks and other fish due to higher fishing pressure. But new research shows there’s one group of predators that’s the exception — moray eels.

Scientists from FIU’s Institute of Environment used a combination of video data from Global FinPrint — the world’s first and largest shark and ray survey — and environmental DNA analysis to conduct the largest study in the Caribbean on moray eel populations.

Reefs located closer to humans usually have higher levels of fishing, which depletes sharks and other large predatory fish. Morays, though, don’t taste very good to people and have little commercial value. Not being a good catch works to their advantage. MORE
