Killer whales, also called orcas, are among Puget Sound’s most distinctive and charismatic inhabitants. They occupy an important niche at the top of the food web and support a multi-million dollar whale-watching industry in Puget Sound. Southern Resident killer whales are a unique population of orcas that ranges in the Salish Sea and the West Coast. While the “transient” or Bigg’s killer whale populations in Puget Sound prey on marine mammals, Southern Resident killer whales primarily eat fish, and depend heavily on Chinook salmon for food.
