Giant marine species found in Antarctica

Large, and possibly new, marine sea creatures have recently been discovered from an unprecedented survey of New Zealand's Antarctic waters.
Some scientists are taken by the large size of some species, such as jellyfish with 12-foot tentacles, giant sea spiders and 2-foot starfish.
But it will take time for research to indicate whether the newly found marine life are in fact actually new species.
"The survey was part of the International Polar Year program involving 23 countries in 11 voyages to survey marine life and habitats around Antarctica," according to an Associated Press article published March 21.
The 12-mile excursion through the Ross Sea turned up a host of never before seen species, which some scientists believe the oddly large size is due to cold temperatures, a small number of predators, high levels of oxygen in the sea water and even longevity— possibly attributed global warming effects.
The Ross Sea is a bay located off of Antarctica's icy coast. The south and north islands of New Zealand are miles from the bay, but contain much of the water currents.
The find also uncovered a hidden nest of sea lilies that coat the ocean floor, and most notably, possibly eight new mollusk species.
