SIBLING RIVALRY

SURROUNDED by a snowstorm, these young polar bears battle the elements - as well as each other. The lumbering pair's sibling rivalry heats up the frosty winter setting in snow swept Alaska. American photographer and tour guide, Matthew Studebaker, 30, managed to capture these extraordinary shots in 25 miles per hour wind on Barrier Islands, Alaska in the Arctic National Wildlife Refuge. No strangers to the freezing weather, the playful polar bears sparred in temperatures of minus six degrees. "These siblings were teasing each other and sparring during a snowstorm," explains Matthew of Richfield, Ohio.
