I’ve heard of a couple sinkings lately. Not that that contradicts your statement about docility, in fact I intend to add to it. Multiple little pods / small groups of species with similar cognition / intelligences (especially elephants, but also whales and often corvids) have been known to get fed up with humans’ shit and go on targeted rampages. They don’t think too dissimilarly from us, and revenge is certainly a pretty big human motivator.
The way elephants traditionally landscape the savannah, using long-term planning, makes me think attempting to weed out rogue humans might also be a pretty rational decision for high cognition animals.
