Air date: Aug 12, 2009

Oceans cover two thirds of our planet. These five massive bodies of water create the largest eco system on the planet. The Pacific, Atlantic, Indian, Arctic and Antarctic Oceans contain some of the most dangerous animals on earth. Unique and venomous creatures hunt in tropical waters, while powerful carnivores rule the icy Antarctic. Ideally suited for survival in their ocean environments, twelve elite creatures stand above the pack, armed with keen intellect, ingenious camouflage, venomous fangs and bone-crushing jaws. Whether hunting or defending, their hardcore weaponry should be avoided at all costs! Dive into their world to experience their full, lethal potential -- and see what happens if we get in their way. They're elusive, powerful and they're dangerous. They are the Oceans Deadly Dozen.
