This week we learned of a new sighting of an all-white killer whale in Russian waters that had not been spotted in four years. For the researchers who caught sight of him, relief that the 22-year-old male orca was still alive mixed easily with the awe they felt witnessing his unusual features.
It's still an open question whether or not "Iceberg," as the whale is known, is a true albino, and we learned in the same story that Iceberg is not the only all-white orca in those waters. There may be as many as eight like him.
Albinism, a genetic mutation that results in no or very little melanin production, touches a variety of animals, though. In Iceberg's honor, we thought it would be fun to revisit some other especially pale animals.
