It’s theory of mind and consciousness level stuff. I don’t really know; I read about it ages ago and that was the conclusion, it was “pod behavior” and not vengeance or something higher-level.

Basically, the bar for a behavior/explanation has to be very high in science.

Orcas began attacking [all] yachts as if they were sentient because their friends got struck by propellers.

Scientists said that orcas are not conscious enough to connect the two things, and that it’s just an example of “pod play”.

Obviously, anyone with half a brain can tell you animals can feel things and hold a grudge, but it’s not scientifically rigorous
