Holy Squid! Photos Offer First Glimpse of Live Deep-Sea Giant Like something straight out of a Jules Verne novel, an enormous tentacle creature looms out of the inky blackness of the deep Pacific waters. But this isn't science fiction. A set of extraordinary images captured by Japanese scientists mark the first-ever record of a live giant squid (Architeuthis) in the wild. The animal--which measures roughly 25 feet (8 meters) long--was photographed 2,950 feet (900 meters) beneath the North Pacific Ocean. Japanese scientists attracted the squid toward cameras attached to a baited fishing line. The scientists say they snapped more than 500 images of the massive cephalopod before it broke free alter snagging itself on a hook. They also recovered one of the giant squid's two longest tentacles, which severed during its struggle. The photo sequence, taken off Japan's Ogasawara Islands in September 2004, shows the squid homing in on the baited line and enveloping it in 'a ball of tentacles.' Tsunemi Kubodera of the National Science Museum in Tokyo and Kyoichi Mori of the Ogasawara Whale Watching Association report their observations this week in the journal proceedings of the Royal Society B. 'Architeuthis appears to be a much more active predator than previously suspected, using its elongated feeding tentacles to strike and tangle prey,' the researchers write. They add that the squid was found feeding at depths where no light penetrates even during the day. Giant Breakthrough Despite people's fascination with this deep-sea behemoth, the giant squid's life and habits have remained largely a mystery. The little information known has been mostly based on dead and dying specimens that were caught by commercial fishing boats or washed ashore. The mysterious creature has inspired countless sea monster tales and has been the subject of various scientific expeditions. Since the mid 1990s there have been a number of research trips in search of giant squid. Cameras attached to deep-diving subs or sperm whales have been used to try to capture the elusive animals on film, but without success. The Japanese researchers used sperm whales as guides to help them pinpoint likely giant squid haunts. Over the years whalers have reported finding a high number of large squid beaks in the mammals' stomachs, pegging sperm whales as primary predators of large squid. The images are generating considerable excitement among squid experts. 'I think it's wonderful that we've finally got a picture of a living giant squid,' said Richard Ellis, a research associate at the American Museum of Natural History in New York and author of The Search for the Giant Squid. 'I thought it would only be a matter of time before someone got images of Architeuthis,' he added. 'After all, it's not an endangered species, not even all that rare, and it's one of the largest of all invertebrates. So the Japanese film finaly breaks through and renders the statement 'nobody has ever seen a living giant squid' inoperative.' Squid expert Martin Collins of the British Antarctic Survey based in Cambridge, England, says the new images are a 'fantastic' achievement. The marine biologist says he was skeptical that a dedicated giant squid hunt would succeed. He thought the first wild sighting would probably come by accident. 'Fair play to these guys who've made the effort, gone out there and looked in what riley thought was a good area, and found it,' he said. Hunting for Clues Collins is especially interested in clues the images might provide to the way giant squid swim and hunt in the deep ocean. 'Seeing the animals on film gives you a tremendous insight into how they live down t
