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.
Reaching combined body and tentacle lengths up to 46 feet (14 m) and weights of at least 1100 pounds (500 kg), the colossal squid is a very large deep-sea predator. Like in many large species, all the largest individuals are female. They eat small and large fishes (including the Patagonian toothfish) and other squids.
