WASHINGTON - A seven-pronged starfish, a mysterious pale octopus and a new kind of yeti crab are among a teeming community of previously undiscovered life on the sea floor near Antarctica, British researchers said. The species, described this week on the online journal PloS Biology, were first glimpsed in 2010 when researchers lowered a robotic vehicle to explore the East Scotia Ridge deep beneath the Southern Ocean, between Antarctica and the tip of South America.

The dark and remote area is home to hydrothermal vents, which are deep-sea springs that spew liquid at temperatures of up to 382 degrees Celsius (720 Fahrenheit), and have previously been found to host unusual life forms in other parts of the world.

“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 lead researcher Alex Rogers of Oxford University.
