Spreading Lionfish Invasion Threatens Bahamas

In 1992, Hurricane Andrew smashed an aquarium tank in Florida. About a half-dozen spiny, venomous lionfish washed into the Atlantic Ocean, spawning an invasion that could kill off local industry along with the native fish.

People come to the Exuma Islands in the Bahamas to kayak between tiny, uninhabited islands and dive in the shallow, turquoise water. Above the water, the landscape looks like a pristine tropical paradise. But the same isn't true beneath the waves.

"In 2005, the first lionfish showed up, and we didn't pay much attention to it," says Oregon State University zoology professor Mark Hixon, who has studied reef fish here for almost two decades.
