Perhaps you've heard the tale of the octopus that broke out of its tank at the aquarium and walked across the room to break into another tank where it proceeded to eat other forms of sea life.
That story is kind of an urban legend. It's supposedly happened at every aquarium in the world, but can't be confirmed. And experts have told me that the hard floors in an aquarium would likely seriously damage the suction pads of any octopus that tried it.
But the basic idea—that an octopus could pop out of the water and move across dry ground&dmdash;is a very real thing. Here, an octopus at the Fitzgerald Marine Reserve in California hauls itself out of the water, and scoots awkwardly around on land for a little bit (while some apparently Minnesotan tourists gawk), before sliding back into the water. It's not the most graceful sort of travel. But it can be very handy. Octopuses do this in nature to escape predators, and also to find food of their own in tidal pools.
As an added bonus: Scientific American just started an all-octopuses, all-the-time blog called The Octopus Chronicles. Check it out!
