Where: Florida, the Bahamas, Belize Want to make an easy $3,500? Stalk the venomous lionfish, a pesky Caribbean predator, at one of the many Lionfish Derbies sponsored by REEF, which gives out first-, second-, and third-place prizes for the most, the biggest, and the smallest lionfish.
Better yet, spear that ostentatious sucker in the face -- no, really, that's how you kill it without getting stung. The day-long competitions, in which teams collect the funky-looking fish by netting or spearing while scuba diving, free diving, or snorkeling, begins at sunrise, and ends at 5pm when you deliver your catch to scoring stations.
Afterwards, demonstrations on proper filleting and dissection show you how to prepare a lionfish. And of course lionfish tastings follow, because nothing screams manliness like spearing and grilling your own dinner.
