The beast measured eight meters (26 feet) long with a body or mantle length of 2 meters (6 1/2 feet). It weighed 250 kilograms (550 pounds).
Wildlife scientists took samples from the creature for further study.
Giant squid can grow to a length of 10 meters (33 feet) or more and weigh in excess of 275 kilograms (600 pounds). The marine mollusk is exceeded only in size by the poorly known Colossal squid (Mesonychoteuthis hamiltoni) which can top 14 meters (45 feet) in length. Earlier this year fishermen in New Zealand captured a Colossal squid for the first time.
The giant squid is somewhat less mysterious to scientists, though still little is known about its biology.

The authors -- Tsunemi Kubodera of Tokyo's National Science Museum, Yasuhiro Koyama of the Japan Broadcasting Corporation, and Kyoichi Mori of the Ogasawara Whale Watching Association -- report that giant squid generally stay at a depth of 600-900 meters during the day but ascend to shallower depths at night to hunt their prey, which consists of fish and smaller squid. Squid were found to be aggressive attackers that use their large triangular fins to maneuver quickly both backwards and forwards.
The authors observed frequent discharge of bioluminescent light flashes which they believe are used by the squid for hunting and communication with other squid.
