Pacific Whale Watching Association reports the orcas, also called Bigg's killer whale T60D, are all business at mealtime, coming onto the scene swiftly, in small groups and without a sound.
About 320 individually identified transient killer whales swim along the West Coast of North America.
Resident orcas’ diets mostly consist entirely of chinook salmon—a food source that’s population has been cut in half since the 1980s. As of last year, there were only 79 resident orcas left.
