We love the questions! Bigg's killer whales don't have any predators. It's thought the coloration is either from the thinner blubber layer of calves or because of a condition like jaundice in human newborns, where the liver isn't fully functioning yet at birth.

Our posts from November 12th and 13th include photos from the superpod. We have more to share, but won't have time to process all our media until our field work is finished next week. You can find a lot more photos and videos on Orca Network and in their latest sightings reports.
