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 squid mainly feeds on soft bodies animals such as fish as well as other squids and needs a sharp cutting beak. While the octopus can and does eat fish (even small sharks), it feeds mainly on crabs (as well as other shelled inverts) and needs that short crushing beak. Squid beak (left) is for tearing. Octopus beak (right) is for crushing. Look like parrot beaks.
