Giant squid attacked Captain Nemo's submarine in Jules Verne's book 20,000 Leagues Under the Sea. But scientists believe that these creatures are not as fearsome as the stories lead us to believe. The truth is we don't know because we have never captured a live giant squid. In fact, only in the last year have scientists figured out where they may be able to find Architeuthis (ark-ee-TOO-this) - that's Greek for Chief Squid. The Smithsonian Institute has put together a truly monstrous World Wide Web site where you can learn everything there is to know about squids of all kinds, the scientists who study squids, and their expedition to New Zealand to try to see one of these enormous sea creatures. You can learn all about the "Expedition into the Depths of the Last Frontier" and the cool technology the scientists may use to actually catch one of these Cephalopods on film. So grab your scuba tank and head over to http://seawifs.gsfc.nasa.gov/squid.html where you can find out more about this gigantic and elusive creature.
