In principle, squid should be a flop

In principle, squid should be a flop.

With no bones, the sea creatures' bodies are soft and squishy. But their beaks – yes, squid have beaks – are rock-hard and knife-edged, like an eagle's, the better to rip apart their prey. A squid's beak, made of one of nature's toughest materials, easily slices through a fish's spine.

Ordinarily, the juncture of something hard and something soft spells trouble. Put dissimilar materials in contact and you can get damage, eventually failure. Think of a flagpole sunk in a muddy ground, or an iron girder bolted to a block of Styrofoam. Something's got to give.
