Venomous, Voracious, Non-native Lionfish Turns Up In Florida Keys

_A beautiful and venomous non-native fish has made its way to the Keys, and the question is whether the species will move north and invade local artificial reefs. . . .

On Tuesday, a diver saw a juvenile lionfish on the Benwood wreck off Key Largo -- it was the first documented case of lionfish in the Keys; the following day, a team from the Reef Environmental Education Foundation captured and euthanized the fish.

"These are voracious predators that eat a lot of fish. They compete with snapper and grouper and eat the young of those species[, said Brian Keller, science coordinator at the Florida Keys National Marine Sanctuary.
