White orcas are a rare find. But Hoyt told The Dodo that this isn't the only one of its kind.
"We have seen one female we call Mama Tanya; a calf; Iceberg the mature male; and now this juvenile," he said. "Four white orcas in all over the past seven to eight years."
It's not yet confirmed by scientists, but some theorize that their white coloring could be caused by albinism, a congenital disorder marked by the absence of pigment in the skin. Another notable white marine mammal was spotted earlier this year during the brutal dolphin hunts in Taiji, Japan. Nicknamed "Angel" by activists, she was taken captive and still lives in a tank at the Taiji Whale Museum.
Researchers continue to pursue these "white whales" - just like Captain Ahab did in search of Moby Dick. But now, all the scientists want is information about these elusive animals.
