As if I needed a reason to not read
The Atlantic. What in the world is that article even about given the title and subtitle? It's behind a paywall. I can't imagine that the author has zero marine mammal experience, which seems to be a common theme amongst
The Atlantic authors (knowing little about that which they write about).
That paragraph you quoted is pretty hyperbolic. Many orcas hunt live and dangerous animals for food. Their prey can seriously injure and even kill them. Because orcas are tight family units with several generations of females and males in the same pod who never leave the pod and because of their intelligence, orcas engage in teaching the younger orcas and each other. So this can very easily look like tortue when it's in fact how orcas train each other to work together. They will also share food readily between each other, so this is why it will also appear to be toying with food.
Yes, there is no doubt that orcas will also legimitaely play with food, but even then, it's a human judgement on a wild animal that can't go pick out meat in a box that comes from an animal raised and slaughtered in a cage.
