Currently classified as the same species, Orcinus orca, they are all distinct variations known as ecotypes. In the Pacific Northwest we have the resident, offshore, and Bigg's killer whales. Now, researchers have confirmed that resident and Bigg's killer whales are entirely different species. Genetic analysis found these orcas likely diverged between 200,000 and 300,000 years ago. “Knowing resident and Bigg's killer whales are unique species is incredibly important from a conservation standpoint. It’s challenging to create effective conservation policies for a globally distributed species like orca because animals in different regions of the world are all facing different threats.” Scripps Institution of Oceanography For the Southern Resident orca, the greatest threat is a lack of food. Research shows that the survival and reproductive success of these orcas is correlated with Chinook salmon abundance. Increasing salmon abundance is an integral component of the species recovery plan.
