Walking Octopuses

Octopuses sometimes try to walk away from predators

Some octopuses apparently realize hiding from your enemies is good, but getting away from them entirely is the best. Scientists have spotted two kinds of octopus on videos using different ways of walking along the sea floor on two arms, while using the other six as a disguise. Octopuses trying to avoid being eaten usually hold still to camouflage themselves. But two from Indonesia wrapped six arms around themselves, looking like coconuts. They then used their two rear arms to move backward. In Australia, another species was seen raising two arms above its head before lifting four more and moving backward on the remaining two. Researchers said it looked like "a clump of algae tiptoeing away."

The report is in tomorrow's issue of the journal Science.
