Using their signature sci-tech style of explosive experimentation, the MythBusters hit the deep blue from California to the Bahamas to investigate myths about sharks. They are honing in on some doozies this year: Do dogs attract sharks? Do the vibrations caused by a flapping injured fish attract sharks? Does chili powder repel sharks? And hosts Adam Savage and Jamie Hyneman create the ultimate SHARK WEEK build – a 16-foot-long robo-shark!

In this special episode of Dirty Jobs Mike heads to the edge of the Arctic Circle, on the northeast side of Canada's Baffin Island in search of one of the most mysterious sharks known to man : the Greenland shark.
