University of Notre Dame graduate students Matthew Barnes and Ashley Baldridge travel to China to better understand why some welcome the introduction of Louisiana crayfish despite the damage the invaders do to native fishes and cropsThey go by various names--crawfish, crayfish, crawdads, mudbugs--but one thing is common to all discussions of the lobster-like freshwater crustacean: they invoke imagery of the Louisiana bayous.

Nestled just off the east coast of Australia, picturesque North Stradbroke Island is a haven for local wildlife. Yet some of the inhabitants of the island's creeks and swamps are far from peaceful. Slender crayfish are aggressive territorial creatures, explains ecologist Robbie Wilson of the University of Queensland, Australia. When two crayfish catch sight of one another, they size each other up in a ritualistic display, which can quickly escalate from careful tapping of their opponent's...

Look for flashes of orange. When you spot a crawdad, grasp it firmly behind the pinchers. The crawdad will brandish its claws in a show of menace, but it can't reach back far enough to pinch you. Joben Jones, 21, recently demonstrated this technique at People's Park in Spokane's Peaceful Valley neighborhood. I...
