When 12-year-old Lauren Arrington heard about her sixth-grade science project, she knew she wanted to study lionfish. Growing up in Jupiter, Fla., she saw them in the ocean while snorkeling and fishing with her dad, according to NPR.
Her project showed that the lionfish can survive in nearly fresh water. The results blew away professional ecologists. The invasive species has no predators on the Florida coast, so if they were to migrate upstream in rivers, they could pose a threat to the ecosystem.
"Scientists were doing plenty of tests on them, but they just always assumed they were in the ocean," Lauren, now 13, tells NPR's Kelly McEvers. "So I was like, 'Well, hey guys, what about the river?' "
