A mature all-white male orca, the only one of its kind known, has been spotted in the North Pacific off the east coast of Russia, scientists announced Monday (April 23). After seeing its towering white dorsal fin breaking through the water's surface, the team named the distinctive beast "Iceberg." The researchers first spotted the mature killer whale with his pod of 13 relatives (shown here) in August 2010 in waters around the Commander Islands. [Read full story about Iceberg]
