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.
While in Monterey Bay, market squid feed heavily on krill (which in May are just beginning to reach adult size). When spawning, however, market squid spend more time in shallow water, close to the seafloor. At this point, they may switch to eating crab larvae, worms, snails, and sometimes others of their own kind.
