A Russian research ship has spotted an extremely rare white adult orca, or killer whale, off the coast of Kamchatka for the first time in history. No one knows the reason for the whale's unusual pigmentation. ­The scientists identified the whale by his pure white fin, swimming together with his pod, or family, all of which have the standard black and white coloration. He has been given the nickname Iceberg, and appears to be behaving normally.
