While there have been examples of white whales in the past—including one orca with a rare genetic condition that died in a Canadian aquarium in 1972 when it was young—nobody has ever observed a fully-grown white orca before. Erich Hoyt, one of the scientists, explains to the BBC:
"We've seen another two white orcas in Russia but they've been young, whereas this is the first time we've seen a mature adult... It has the full two-metre-high dorsal fin of a mature male, which means it's at least 16 years old - in fact the fin is somewhat ragged, so it might be a bit older."None of the researchers know why he is white, though. He could suffer from straight-forward albinism—or there could be some other reason for his lack of pigmentation. The researchers are currently considering taking a biopsy from Iceberg to find out more—but will only do so if there's a compelling conservation reason to interfere with him. In the meantime, Captain Ahab's got a new target. [BBC]
