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.
Squids range in size from the giant squid (Architeuthis sp.) to the smallest Idiosepius sp. The largest giant squid ever recorded (Architeuthis princeps) was captured in 1878. One of the arms (probably a tentacle) measured 35 feet long. It is estimated that the animal weighed in the neighbourhood of 4000 pounds.
