Since ancient times, sightings of a massive, eight-legged sea creature has spawned myths of a monster that can sink boats and swallow men. The Giant Pacific Octopus can grow up to one hundred pounds with an arm-span of sixteen feet. It can roam six thousand feet below the ocean surface. It's a escape artist, and the most intelligent of all invertebrates on the planet. Now, NATIONAL GEOGRAPHIC WILD is revealing the hidden secrets of this incredible predator. In this special event, we're pitting the Giant Pacific Octopus against a human to see how they match up in the reams of INTELLIGENCE, PROBLEM SOLVING, FLEXIBILITY, ADAPTATION, and STRENGTH.
