Pictured: A smiling polar bear lazily floats belly-up in a pool of water. The happy bear is just one year old and lives with his mother in a German zoo, and could weigh as much as ten men when fully grown. The marine mammals actually have black skin, but their translucent fur reflects visible light, making it appear white. These photographs were taken by hobby wildlife photographer Antje Wenner-Braun, at the Hannover Adventure Zoo in Northern Germany.
