Invasive lionfish may be a selective predator

Smithsonian Tropical Research Institute
Peer-Reviewed Publication

The invasive lionfish has become a growing threat to the ecological balance of Atlantic waters. To gather insight regarding its impact on reef communities, scientists at the Smithsonian Tropical Research Institute (STRI) and collaborating institutions evaluated the predatory behaviors and diet choices of lionfish in a semi-natural environment. Their experiments revealed that most of them actively selected their prey species.
