Behaviour 

Northern resident killer whales are the only population known to rub on beach stones. Beach rubbing, as it’s called, is a highly ritualized social behavior that occurs in only a few locations.   The whales become excited as they approach   the rubbing beaches , blow the air out of their lungs so they sink, and scrub their bodies on smooth stones in the shallows.
The best-known rubbing beach is in the Robson Bight-Michael Bigg Ecological Reserve in Johnstone Strait.


Northern residents are primarily found off the northern tip of Vancouver Island and the North and Central Coast of BC. 


Northern residents are the only group of killer whales known to participate in 'beach rubbing'.
