FORT LAUDERDALE, Fla. (AP) — Step aside, Burmese python — you may no longer be Florida's scariest invasive species. Researchers have confirmed that three Nile crocodiles were captured near Miami, and they say it's possible more of the man-eating reptiles are still out there, although no one can say for sure. The big question now: How did they get to Florida? "They didn't swim from Africa," University of Florida herpetologist Kenneth Krysko said. "But we really don't know how they got into the wild."
