A team of scientists from Russia is preparing for an expedition to track down a rare all-white killer whale that hasn't been seen since it was spotted 18 months ago.
"Iceberg," as the whale has been named, was first seen near the Commander Islands off the coast of Russia's Kamchatka Peninsula in the north Pacific in August 2010, according to Agence France-Presse.
The Far East Russia Orca Project (FEROP), the group that led the expedition, says that the whale may be albino, meaning that it lacks pigment in the skin.
