188 Photo of the Day: The Emperor Penguins

Paul Nicklen of Canada won 1st Prize in the Nature Stories category for his photographs of Emperor Penguins. Scientists discover that Emperor Penguins are capable of tripling their swimming speed by releasing millions of bubbles from their feathers. These bubbles reduce the friction between their feathers and the icy seawater, allowing them to accelerate in the water. (Paul Nicklen/ National Geographic Magazine)
