In September 2004, off the shores of Japan’s Ogasawara Islands, local scientists captured the first ever recorded images of a live Giant Squid (Architeuthis). Scientists used Sperm Whales, known predators of the giant squid, as their guides for pinpointing areas where the giant squid may reside. Previously, scientists have only been able to study carcasses of giant squids that washed up on shore or were caught by fishermen.
Scientists attracted the 25 feet (8 meters) long Cephalopod with a baited fishing line at depth 2,950 feet (900 meters). Along with a tentacle that was severed during the squids fight to free itself from the line the sequence of images offer a great deal of information on the behaviour of these behemoths. According to scientists if the tentacle was not severed at the base, as they believe, the squid could have been significantly longer than estimated.
