Scientists investigating the icy waters of Antarctica said Tuesday, Feb. 19, 2008, they have collected filmed mysterious creatures including giant sea spiders and huge worms living in the murky depths. Australian experts taking part in an international program to take a census of marine life in the ocean at the far south of the world collected specimens from up to 2,000 meters (6,500 feet) beneath the surface, and said many may never have been seen before.
