Bizarre New Deep-Sea Creatures Found Off Antarctica

A treasure trove of more than 700 new species has been uncovered in the dark depths of oceans surrounding Antarctica, researchers report. (See a photo gallery of the finds.)

Heart-shaped sea urchins, carnivorous sponges, and giant sea spiders the size of dinner plates are among the surprising discoveries brought up from the seafloor about 2,300 to 19,700 feet (700 to 6,000 meters) beneath the Antarctic waves.
