Unfortunately, the giant squid Architeuthis has not been studied enough to make a comprehensive diet. From the few that have been dissected though, it was discovered that they would eat sperm whales that dive deep underwater.
Squids lack teeth, but they have other hard mouthparts that they use to break food down before passing it into their digestive tracts. Squid use their suction cups to catch prey, which they quickly tear up using their sharp, horn-shaped beaks akin to those of parrots.
