Giant squid, just like other kinds of squid, capture their prey by using their two long feeding tentacles. These tentacles have many suckers on the tips, on the ends. These are called clubs, and the tentacles are shot out to grab the prey, and then the tentacles contract, bring the prey into the arm crown, the crown of eight arms where the prey is held, and chunks are bitten out of the prey by beaks. Now the beaks, or jaws, are very much like a parrot's beak.
But they are encased in a huge muscular ball so they're extremely powerful and they're very sharp. The beaks are made out of a material like chitin, similar to chitin, which is like shrimp shell, for example, or even like our fingernails, only chemically somewhat different. The point is that the beaks are very sharp, strong and powerful.
