Usually we think of crayfish as a common Southern food pulled from rivers. However a surprising number of crayfish species are on the decline. Those on the Endangered Species list include the White-clawed Crayfish (pictured above), the Phantom Cave Crayfish, the Slenderclaw crayfish, the Giant Freshwater Crayfish and the aptly named Sweet Home Alabama crayfish of Marshall county, Alabama. If that last one doesn't have you worried about the future of crayfish cook-offs, we don't know what will!
