New Species of Sea Anemone Discovered in Antarctica

Published

on

A robot surveying the underside of Antarctica’s Ross Ice Shelf has made a startling discovery: Clinging upside-down from crannies in the ice shelf with their tentacles dangling into the icy water were thousands and thousands of tiny sea anemones.

The creatures are a new species dubbed Edwardsiella andrillaeOther anemones have been found in Antarctica, but these are the first reported to live in the ice. The tiny, white invertebrates reside in burrows in the ice and extend their tentacles to filter-feed from the water below.

The finding, detailed in the December 2013 issue of the journal PLOS ONE, was a complete surprise.

“When the robot got down, the engineers noticed the ice looked kind of fuzzy, and when it drifted up to take a look they saw anemones, and knew it was really something special,” said Frank Rack, science leader of the Antarctic Geological Drilling Program at the University of Nebraska-Lincoln. Other groups have drilled through Antarctic ice shelves before, he said, “but nobody looked up.”

The team’s actual mission was to survey ocean currents near the Ross Ice Shelf, a slab of ice extending more than 600 miles (970 kilometers) northward from the grounding zone of the West Antarctic Ice Sheet into the Ross Sea, to model the behavior of a drill string, a length of pipe extending to the seafloor which delivers drilling fluids and retrieves sediment samples. The work is part of a larger effort to study what Antarctica was like before its glaciers formed.

Rack and his team drilled a hole through the 890-foot-thick (270 meters) ice shelf and lowered down a robotic vehicle known as the SCINI ROV (Submersible Capable of under-Ice Navigation and Imaging – Remotely Operated Vehicle) on a tether. The robot contained two cameras: one that looked forward and one that normally faced down.

Swimming upside down, the robot trained its cameras on the anemones, which seemed to be glowing. The anemones probably feed on detritus and the upwelling of nutrient-rich water. The ice under the front of the shelf is melting at a rate of about 3.3 feet (1 meter) per year, so the creatures must be burrowing to stay inside the ice, Rack said. Scientists don’t really know how far the creatures extend, but it could be hundreds of miles.

Until 28 November, prizes worth a massive £10,000 – including experiences, products and tuition – feature in a line-up of items that can be won for £5 in an online prize draw to celebrate Bite-Back Shark & Marine Conservation’s 20th anniversary and help generate crucial funds for the future.

Top of the list of prizes is the chance to spend time with adventurer and wildlife expert Steve Backshall, a workout session with Nat Geo star Aldo Kane, a kayaking trip alongside white-water expert and diver Sal Montgomery and a Zoom call with ‘shark whisperer’ Cristina Zenato.

On top of that, some of the most admired companies in the diving and scuba industry have been quick to support the charity with fabulous prizes that make the £5 ticket price worth more than just a flutter.

Master Liveaboards, BSAC, Midlands Diving Chamber, Go Freediving and Blue Shark Snorkel have all generously donated experience prizes, while celebrated photographer Alex Mustard has donated a print and artists Scott Gleed and Olivier Leger have donated a sculpture and illustration to help boost the fundraising pot.

Fourth Element has donated Ocean Positive gear and LA watch company Nodus has gifted the charity a stunning dive watch. For land lovers, the charity has included a five star London hotel stay at Bankside Hotel plus a family visit to Longleat Safari Park in the roster of prizes.

Campaign director for Bite-Back, Graham Buckingham, said: “We’ve been overwhelmed with support from companies and individuals that we truly admire and who have supported us on our 20 year journey and we’re truly grateful to them all. While we feel incredibly proud of our achievements over the past two decades – and we are super excited about the next chapter – this prize draw isn’t a vanity project. It represents a real lifeline to our work and important advancements in the global protection of sharks. So we hope divers, dive clubs and even bargain hunters grab some tickets to make this a massive success.”

The charity hopes that the prize draw will generate crucial funds to launch a brand new, ground-breaking, campaign to enrol the public and increase support for the protection of sharks around the world.
