Ghost Octopuses and Yeti Crabs

Weird life flourishes at deep-sea vents the world over, but no one had ever found hydrothermal vents in Antarctica, explained Jon Copley, a professor of earth and ocean science at the University of Southampton who also participated in the research. That's largely because it's more difficult to do research in the harsh Southern Ocean than in temperate climes. [Extremophiles: World's Weirdest Life]
"It's only quite recently that we've been able to be bold enough, really, to head to the poles," Copley told LiveScience.
In 1999, Antarctic mapping surveys turned up hints of hydrothermal vent output in the water column over the East Scotia Ridge in the Atlantic section of the Southern Ocean, between Antarctica and South America and eastward. It took 10 years for researchers to get back for a full-blown expedition, during which they lowered cameras to two areas, 8,530 feet (2,600 meters) and 7,874 feet (2,400 m) deep, catching the first glimpses of Antarctic hydrothermal vents. Among them were "black smokers," chimney-like vents that emit dark-hued, superheated water.
Although the background temperature of the Southern Ocean in the area is 32 degrees Fahrenheit (0 degrees Celsius), the black smokers gushed water as hot as 721 degrees F (382 degrees C).

THE CONTROVERSIAL FAROE ANNUAL WHALE HUNTING
5:27 PM
Anonymous
Whaling in the Faroe Islands in the North Atlantic has been practiced since about the time of the first Norse settlements on the islands. It is regulated by Faroese authorities but not by the International Whaling Commission as there are disagreements about the Commission's competency for small cetaceans.
Around 950 Long-finned Pilot Whales (Globicephala melaena) are killed annually, mainly during the summer. The hunts, called "grindadráp" in Faroese, are non-commercial and are organized on a community level; anyone can participate. The hunters first surround the pilot whales with a wide semicircle of boats. The boats then drive the pilot whales slowly into a bay or to the bottom of a fjord.
Most Faroese consider the hunt an important part of their culture and history. Animal-rights groups criticize the hunt as being cruel and unnecessary. As of the end of November 2008 the chief medical officers of the Faroe Islands have recommended that pilot whales no longer be considered fit for human consumption because of the levels of toxins in the whales.
The American Cetacean Society says that pilot whales are not considered to be endangered, but that there has been a noticeable decrease in their numbers around the Faroe Islands.
