TV's most extreme survival challenge just grew extra-large. Veteran survivalists familiar with the stripped-down drill after appearing on "Naked and Afraid" attempt to survive in a desolate, dangerous environment for 40 days -- 19 more than they previously experienced on the show. Pushing the very limits of human endurance, the men and women must all vie for the same limited food, water and shelter while avoiding territorial-sensitive predators and venom-filled reptiles. Because there is no other choice, the competitors quickly get to know one another -- and their surroundings -- and hope that their instincts, survival skills and intestinal fortitude serve them well.

Discovery Channel takes the ubiquitous survival show theme to the next level by stripping it to its bare essentials. In "Naked and Afraid," complete strangers -- usually a man and a woman -- meet in a very unique way: They're stranded in a dangerous, desolate location, without food or water, and they're completely naked. Each episode follows the adventurers as they attempt to survive on their own with nothing but a personal item and the knowledge that the only prize is their pride and sense of accomplishment. Because there is no other choice, competitors quickly get to know one another -- and their surroundings -- and hope that their instincts, survival skills and intestinal fortitude serve them well.

Veteran reality TV adventurer Ed Stafford is back, this time testing the extreme limits of human endurance and determination and hoping he's the "first man out."

His competitors include EJ Snyder ("Dual Survival," "Naked and Afraid"), Matt Graham ("Dual Survival," "Bushcraft Build Off"), Cat Bigney ("The Great Human Race"), Ken Rhee ("Ultimate Hell Week"), John Hudson ("Dude You're Screwed") and ex-military expert Commando Sniper Aldo Kane.

The producers of National Geographic Channel's hit series "Life Below Zero" are behind "Port Protection," which profiles individuals trying to survive way above the Lower 48. Surrounded by the North Pacific, Port Protection is a remote community tucked into the northwest corner of Prince of Wales Island, Alaska. The approximately 100 residents who call the rugged, unforgiving land home push the limits of survival, living an isolated and risky existence of self-reliance with no roads, government or law enforcement. However, they think the risk is worth the profound reward: a world of beauty with the security of community without the constraints of bureaucracy.
