A polar bear travels submerged under water - a tactic often employed to surprise prey. As part of a fragile Arctic ecosystem, the bears are threatened by the recent dramatic reduction in ice cover. Sea ice - frozen seawater that moves with the ocean currents - provides an important habitat and resting place for many animals. The Artic ice cover reached a record low in 2007. Many attribute this situation to global warming.
With ivory tusks up to 8 feet long, a pod of male narwhals, known to some as unicorns of the sea, breath before heading back under the ice to gorge on polar cod. Algae and plankton grow on the underside of the sea ice, copepods and amphipods feed on the plankton, cod feed on the amphipods, narwhals feed on the cod and polar bears occasionally feed on narwhals. So goes the cycle of life in the Arctic.
