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.
On 4 December 2006, an adult giant squid was caught on video near the Ogasawara Islands, 1,000 km (620 mi) south of Tokyo, by researchers from the National Science Museum of Japan led by Tsunemi Kubodera. It was a small female about 3.5 m (11 ft) long and weighing 50 kg (110 lb). The bait used by the scientists initially attracted a medium-sized squid measuring around 55 cm (22 in), which in turn attracted the giant squid.
