An extremely rare white killer whale - the first adult of its kind ever spotted - has been rediscovered by scientists. The whale, who they have named Iceberg, was seen off the coast of Russia's Kuril Islands.
Iceberg was last spotted in 2012 off the coast of Kamchatka in eastern Russia, and seems to be still enjoying a healthy life in its pod. The 22-year-old white whale is the only adult Orca ever to have been spotted in the wild. Just one in ten thousand killer whales are completely white.
