Wildlife Photographer of the Year 2012

Winner: "Bubble-jetting emperors" by Paul Nicklen (Canada). A blast of penguins from the depths of the Ross Sea, Antarctica. "It was a fantastic sight as hundreds launched themselves out of the water and onto the ice above me, a moment that I felt incredibly fortunate to witness and one I'll never forget," Nicklen told the contest's sponsors.
