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 eight arms of the Colossal Squid also carry fixed hooks which the Giant Squid does not have. Both the Colossal Squid and the Giant Squid live in deep water, perhaps as much as 3,300 feet (1000 meters) or more beneath the surface, where there is very little light. To help them hunt their prey in the darkness at that depth they have extremely large eyes.
