SWS reader Nick West sent us this photo of a spiky specimen he caught off Bermuda. Once again we turn to our resident expert for the ID-Dr. Tomio Iwamoto of the California Academy of Sciences. This is an easy one. It's a long-spine porcupinefish (a.k.a. balloonfish). When threatened, the porcupinefish inflates, extending the long, sharp spines that cover its body.
