"The Whale That Ate Jaws" - Shark Thread!!!!

I've been watching that show on Nat Geo, "Expedition: Great White", where they catch a great white shark as it cruises off Guadalupe Island near Baja California. They actually catch them and get them out of the water with a lift attached to a larger ship. They attach a satellite tracking device to their dorsal fin to track them as they move around the oceans. The female great whites are much larger and fatter than the males, the males come back to the island every year where as the females appear every other year, the scientists think the sharks come to the island to mate. They feel the females are going somewhere to give birth, they are trying to figure out where.
