DIRTY JOBS: SHARK SPECIAL
Premieres Tuesday, July 29, at 10 p.m. ET/PT.
With over 400 species of sharks, they don't all live in the warm waters of the tropics -- some inhabit the freezing cold waters of the Arctic. And who better to introduce viewers to one our planet's most unsung sharks than DIRTY JOBS' Mike Rowe, who travels north to the edge of the Arctic Circle in search of the mysterious Greenland shark. These large sharks are slow-moving behemoths, and learning more about them will help scientists understand the rapid ecological changes affecting that part of the world, and how the Greenland shark impacts the food chain there. Mike assists shark scientists with their research as they tag and release a large male Greenland shark. By the end of the trip, Mike gains a deep appreciation for the men and women who are studying this elusive shark in one of the most extreme climates known to humankind.

HOW NOT TO BECOME SHARK BAIT
Premiering Tuesday, July 29, at 10 p.m. ET/PT.
Sharks may have a bad reputation, but you actually have a very slim chance of being attacked by one. A thrill-seeking team with a purpose -- escapologist Jonathan Goodwin, former lawyer turned Survivor: Cook Islands winner and adrenaline junkie Yul Kwon, marine biologist Jeremiah Sullivan and scientist Dr. Marty Jopson -- travel to the Bahamas to test shark attraction theories on lemon, tiger and Caribbean reef sharks, focusing on the sensory perception of sharks including colors, vibrations, smells and other attractors. In the process, viewers learn strategies for staying safe when in the water.
