Southern resident orcas. The waters of the Salish Sea, on the west coast of North America, are home to several ecologically distinct populations of orcas (Orcinus orca).The area supports three major ecotypes of orcas: northern residents, southern residents, and transients.
Over 2,000 individual resident-like orcas and 130 transient-like orcas have been identified off Russia. [29] At least 195 individual orcas have been cataloged in the eastern tropical Pacific, ranging from Baja California and the Gulf of California in the north to the northwest coast of South America in the south and west towards Hawaii.

The southern resident orcas, also known as the southern resident killer whales (SRKW), are the smallest of four communities of the exclusively fish-eating ecotype of orca in the northeast Pacific Ocean. The southern resident orcas form a closed society with no emigration or dispersal of individuals, and no gene flow with other orca populations. [1]

In addition, the sea hosts 37 marine mammal species, most notably Steller sea lions, humpback whales, and killer whales (orcas). While mammal-eating transient orcas are gradually increasing in population, fish-eating southern resident orcas have struggled to survive due to low salmon populations and inbreeding. [36] In 2019, this orca ...
