A 12-year-old Florida girl's science fair project on invasive lionfish has surprised even seasoned ecologists, and led to the first published paper on lionfish freshwater tolerance.
Lauren Arrington's relatively simple experiment (put captured lionfish in water of varying saltiness, see if they live) revealed that lionfish can survive much fresher water than anyone expected . . . meaning the rapidly-spreading invasive marine species may also pose a threat to vulnerable life in brackish estuaries.
