Ice-loving sea anemones discovered in Antarctica
Date:1/16/2014

ll string, Rack said. They didn't expect to discover any organisms living in the ice, and surely not an entirely new species.

The discovery indicates that, even after 50 years of active U.S. research, more remains to be studied about the southernmost continent, said Scott Borg, head of the Antarctic Sciences Section in the NSF's Division of Polar Programs.

"Just how the sea anemones create and maintain burrows in the bottom of the ice shelf, while that surface is actively melting, remains an intriguing mystery," he said. "This goes to show how much more we have to learn about the Antarctic and how life there has adapted."

Rack, who is U.S. principal investigator for the environmental surveys that were conducted as part of the international ANDRILL Coulman High project, had left the site just prior to the discovery. He was listening by radio when he heard the report from the robot deployment team -- engineers Bob Zook, Paul Mahecek and Dustin Carroll -- who began shouting as they saw the anemones, which appeared to glow in the camera's light.

"They had found a whole new ecosystem that no one had ever seen before," Rack said. "What started out as a engineering test of the remotely operated vehicle during its first deployment through a thick ice shelf turned into a significant and exciting biological discovery."

In addition to the anemones, the scientists saw fish that routinely swam upside down, the ice shelf serving as the floor of their undersea world. They also saw polychaete worms, amphipods and a creature they dubbed "the eggroll," a 4-inch-long, 1-inch-diameter, neutrally buoyant cylinder that seemed to swim using appendages at both ends of its body. It was observed bumping along the field of sea anemones under the ice and hanging on to them at times.

The anemones measured less than an inch long in their contracted state -- though they get three to four times longer in their relaxed state, Daly said. Each fe
