Octopuses are tough--and not just in the sense that they can take out sharks (both real and computer generated, as in ). They're almost pure muscle. With tridirectional muscles in the arms, they're a tad less supple than a well-marbled sirloin, to say the least (though certainly a lot more healthful). So over the centuries, people have been finding ways to make them a little easier on the jaw. The classic tactic is beating the bejesus out of them on rocks.
