They look different but look at homo sapiens, the variance is quite a bit less. They definitely look like the same species to me.
Also there’s a huge difference between a species doing poorly and the species changing its habits / dominant feeding areas, especially for species that are highly nomadic.
- pvaldes 5y agoLets 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.
- detaro 5y agoThe entire "is it a different species" discussion is missing the point, because their protection status isn't based on them being a different biological species, so the initial claim of "pretending they are a different species" already doesn't make sense.
