Shark Men

World-class anglers and a renowned shark scientist spend two months at sea studying great white sharks. The crew, which includes actor Paul Walker and expedition leader Chris Fischer (the former host of `Offshore Adventures'), uses a specially modified hydraulic cradle to lift the massive creatures out of the water. They then mount each one with a tracking tag and take measurements and DNA samples, all while pumping water into its mouth to keep it alive. After a harried 20 minutes, the sharks are released unharmed.
