HUNTING THE LIONFISH
Diving around a coral reef, Ted shines a light under every ledge, looking for lionfish and the fish they like to eat. After a few minutes, he waves his light frantically under an overhang. 
A lionfish the size of a football fans the water with its huge, quilled fins. These days, the only thing unusual about spotting a lionfish off the Florida coast is seeing just one of them.
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.
Back on the boat, Ted is upbeat. Last year his team pulled more than a dozen lionfish off of various South Florida reefs. But admits that divers can only catch so many.
Until marine predators or parasites learn to feed on lionfish, the best hope for slowing the spread may be humans. The fish are a delicacy in Asia, but not in the Unites States, given the painful sting their spines can inflict. A few restaurants serve lionfish now, and there's an effort to teach divers how to catch and cook them.
