In this Sept. 7, 2012, photo, the research vessel Ocearch has set her anchor as the crew begins their search for great white sharks on the Atlantic Ocean, spending two to three weeks tagging sharks and collecting blood and tissue samples off the coast of Chatham, Mass. The Ocearch team baits the fish and leads them onto a lift, tagging and taking blood, tissue and semen samples up close from the world’s most feared predator. The real-time satellite tag tracks the shark each time its dorsal fin breaks the surface, plotting its location on a map. (AP Photo/Stephan Savoia) less
