I wonder if this lends any more credence to stories of giant octopi attacking ships in the old days? Perhaps old sailing vessels looked like tasty sharks or whales passing by? Follow the digg story link back to a video of an octopus killing a shark at an aquarium in Seattle. Impressive!
From DIGG:
A giant octopus takes on a shark in a video like something from a horror movie, Octopuses are remarkable creatures, and are much more intelligent than you may think.
