A rare, prehistoric shark was caught on camera last January 21, 2007. Frilled sharks, named after it's frilled gills, generally remain thousands of feet beneath the water's surface. This serpentine specimen may look like a large eel, but its six slitlike gills help mark it as a cousin of the great white, the hammerhead, and other sharks. With a mouthful of three-pointed teeth, the frilled shark may be a fearsome hunter, but it's considered harmless to humans as it's main diet is deep sea squids and other sharks.

"We think it may have come to the surface because it was sick, or else it was weakened because it was in shallow waters," a park official told the Reuters news service. But the truth may never be known, since the "living fossil" died hours after it was caught.
