Humbolt Squid have crazy beaks

I saw this and thought it was pretty cool:

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.

This question has haunted many a marine biologist. So recently a team of materials scientists at the University of California decided to carefully examine the physical properties of the beak. Their discovery? The beak contains a huge gradation of stiffness: The tip of the beak is 100 times more rigid than the base of the beak — so the base can blend easily with the surrounding flesh. Water is the key to the proper functioning of this gradient: If the beak is dried out, the soft base calcifies until it’s nearly as dense and rigid as the peak.

Those beaks are nuts! after cleaning a cooler full of them, I set the beaks out to dry at the artist community at which ilived. They caused quite a stir.
 what about their miss named "suckers"...more like tiny cat claws.Like 8 or so per "sucker". On my first HS trip, i tried using a ling style mondo glow swirly tailed grub on a 16 oz head. they tore it into chunks within seconds with their "suckers".
I think their "ink" also contains a histamine or other irritant. It burnt after being inked, and I'm not particularly susceptible to things like poison oak.
Lastly, their bio luminescence . After cleaning i left the few i kept for crab bait in a cooler overnight due to fatigue.when i went to deal with them,the garage light had blown, and i was in the dark. when i opened the cooler, it glowed so bright lumo green you could EASILY read by the light, and see everything in the garage! The brightest glow in the dark substance Ive ever seen!
