Friday Squid Blogging: The Mystery of Humboldt Squid Beaks
There are many weird things about the giant Humboldt squid, but here’s one of the strangest: Its beak. The squid’s beak is one of the hardest organic substances in existence—such that the sharp point can slice through a fish or whale like a Ginsu knife. Yet the beak is attached to squid flesh that itself is the texture of jello. How precisely does a gelatinous animal safely wield such a razor-sharp weapon? Why doesn’t it just sort of, y’know, rip off? It’s as if you tried to carve a roast with a knife that doesn’t have a handle: It would cut into your fingers as much as the roast.
