I don't blame the orcas - have you seen a human? Those things are, like, 1/3 of the size of an orca; they're clearly malnourished, some good ol' seal meat will fix'em up real good!
Serious now. I think it's interesting how they're interacting cooperatively, with an animal of a different species. And it isn't like either side domesticated the other (unlike, say, humans vs. dogs and cats); they don't even live in the same environments, at most you have some humans doing short trips into the sea and that's it.
“What I think in a sense is more impressive is that humans basically give no credit to any other creature for having a mind,” Safina said. Yet many other creatures, including orcas, understand implicitly that humans have minds. “So they understand us, and give us more credit there, they seem to comprehend the world better than we do, in our self-imposed estrangement.”
I feel like this is a step beyond theory of mind already.
