'Lost world' discovered around Antarctic vents
Date:1/3/2012

Communities of species previously unknown to science have been discovered on the seafloor near Antarctica, clustered in the hot, dark environment surrounding hydrothermal vents.

The discoveries, made by teams led by the University of Oxford, University of Southampton and British Antarctic Survey, include new species of yeti crab, starfish, barnacles, sea anemones, and potentially an octopus.

For the first time, researchers have used a Remotely Operated Vehicle (ROV) to explore the East Scotia Ridge deep beneath the Southern Ocean, where hydrothermal vents, (including 'black smokers' reaching temperatures of up to 382 degrees Celsius) create a unique environment that lacks sunlight, but is rich in certain chemicals. The team reports its findings in this week's issue of the online, open-access journal PLoS Biology.

"Hydrothermal vents are home to animals found nowhere else on the planet that get their energy not from the Sun but from breaking down chemicals, such as hydrogen sulphide," said Professor Alex Rogers of Oxford University's Department of Zoology, who led the research. "The first survey of these particular vents, in the Southern Ocean near Antarctica, has revealed a hot, dark, 'lost world' in which whole communities of previously unknown marine organisms thrive."

Highlights from the ROV dives include images showing huge colonies of the new species of yeti crab, thought to dominate the Antarctic vent ecosystem, clustered around vent chimneys. Elsewhere the ROV spotted numbers of an undescribed predatory sea-star with seven arms crawling across fields of stalked barnacles. It also found an unidentified pale octopus, nearly 2,400 metres down, on the seafloor.

"What we didn't find is almost as surprising as what we did," said Professor Rogers. "Many animals such as tubeworms, vent mussels, vent crabs, and vent shrimps, found in hydrothermal vents in the Pacific, Atlantic, and Indian Oceans, simply weren't
