Offshore: A third population of orcas in the northeast Pacific was discovered in 1988, when a humpback whale researcher observed them in open water. As their name suggests, they travel far from shore and feed primarily on schooling fish . [ 25 ]
Offshore orcas, first described in 1979, are primarily found more than 10 miles (16 km) from shore. Just over 280 offshore orcas are known from the Eastern North Pacific, primarily occurring off the coast of British Columbia.
The orca (Orcinus orca), or killer whale, is a toothed whale and the largest member of the oceanic dolphin family. It is the only extant species in the genus Orcinus and is recognizable by its black-and-white patterned body. A cosmopolitan species, it is found in diverse marine environments, from Arctic to Antarctic regions to tropical seas.

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.
Water depth and the type of habitat — rocky, sandy or coral reef — also played roles in the approaches the whales took. Drone imagery shows a gray whale using a side-swim technique to find food.
