Lets see. Genetically different microsatellite DNA and mitochondrial DNA. Unique vocalisations than don't share with offshore, transient or northern resident orcas. Never had seen in company of the other resident orcas. And northern resident orcas don't go South of Oregon. The 80% of its diet is chinook salmon, therefore they are clearly different in diet, hunt techniques and ecology than offshore or transient orcas. And very different also to the subantartic type (D). This mean also that we aren't prey, and they tolerate [1] humans that behave and keep the distance (I wouldn't put my money on the bigger meat eater species being so tolerant to us. > They are highly nomadic Some orcas are nomadic, other not so much. Resident orcas are, hum... resident. Is in the name. They migrate North and South of the west coast following the salmons but will not end in the Mediterranean, for example. [1] Of course if you attack any orca or try to approach a cub in the sea and they see it as harassment, the family will react and you will be in a serious trouble.
