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.
Although it is not clear why they engage in this activity, beach rubbing has been identified as an important activity to the culture of the entire Northern resident community.
