Giant sea creatures found in Antarctica

Scientists who conducted the most comprehensive survey to date of New Zealand's Antarctic waters were surprised by the size of some specimens found, including jellyfish with 12-foot tentacles, 2-foot-wide starfish, large sea spiders, huge sea snails, and "fields" of sea lilies that stretched for hundreds of yards across the ocean floor. Cold temperatures, a small number of predators, high levels of oxygen in the sea water and even longevity could explain the size of some specimens.
