Hunting lionfish off the Florida coast

Though they’re native to the Indian and Pacific oceans, the voracious lionfish have overwhelmed reefs in Florida and parts of the Caribbean. “They’re gluttonous eaters, so they will decimate the native fish population,” says Allie ElHage, who has made hundreds of dives off the Florida coast to help keep lionfish in check. In this excerpt from America Tonight, Sheila MacVicar travels to South Florida, ground zero of the lionfish invasion, to find out what locals are doing to protect the state’s native wildlife from this delicate but dangerous predator.
