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.
Those of the giant squids reach a length of 10 meters for the tentacles, and 3 meters for the arms. The tentacles are what are used to catch prey. The lower surface of these arms is covered with two rows of suckers. The tentacles of squid and octopi do have a difference. Squids have extra armature-hooks on the sucker rings.
