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.
The giant squid has a torpedo-shaped body, called the mantle. Two small fins protrude from the thinner end. At the other end is the head, with eyes as big as volleyballs, the largest of any known animal! The giant squid's mouth is equipped with a hard, sharp beak and a raspy, tongue-like organ called a radula.escription. Squids belong to the class of animals called cephalopods, which means, head-foot.. The animals in this group are soft-bodied, marine invertebrates with arms attached directly to their heads. Octopuses, cuttlefishes and nautiluses are head-foots too.
