Check out this video of an octopus literally crawling out of the water and dragging itself across dry land in pursuit of a meal. A family with a camera was lucky enough to be on the scene and captured the whole thing on video:


If you're curious to learn more about the sea creature's possible motivation, there has been some great research on the understanding of octopus intelligence recently, including this surprisingly moving article , in Orion magazine chronicling a researchers bond with a giant Pacific octopus named Athena.

As it turns out, walking on land in the octopus kingdom is not as unique as you might think:
Some would let themselves be captured, only to use the net as a trampoline. They'd leap off the mesh and onto the floor - and then run for it. Yes, run. "You'd chase them under the tank, back and forth, like you were chasing a cat," [Middlebury College researcher Alexa] Warburton said. "It's so weird!"

Octopuses in captivity actually escape their watery enclosures with alarming frequency. While on the move, they have been discovered on carpets, along bookshelves, in a teapot, and inside the aquarium tanks of other fish - upon whom they have usually been dining.
However, it's quite unusual to capture video of a walking octopus in action. Part of the reason that studies on the creatures have been so limited, aside from their brief three-year life spans, is that they are notoriously shy, usually avoiding contact not only with humans, but with any other creatures, including fellow octopi.
