In this photo released by the Australian Antarctic Division, the Antarctic sea-bed covered with a mixture of sponges, bryozoans, hydroids and octocorals which form a home to many species of fish and other marine life is seen in Antarctic waters in January 2008. Scientists investigating the icy waters of Antarctica said Tuesday, Feb. 19, 2008, they have collected 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.
