I did not say nor imply "not formidable". I said and meant "quite a bit more formidable". But, to your point: the overwhelming majority of humans killed by hyenas are killed by packs of hyenas, not individuals, and there is a reason for this. I definitely dispute the idea that a single modern hyena can kill a human "trivially".

Particularly a human with a pocket full of stones.

I love how the leopard looks over its shoulder with a look that I anthropomorphized as an incredulous gaze, similar to the one my cat gives as my border collie runs around the house. "Can you believe this?"

> I actually found this video where a hyena basically took what it wanted from a leopard before the leopard took its prey up a tree. (Warning: predators with dead prey.) > https://youtu.be/cYzogF9IVLI

The two animals were surprisingly "civil" given the amount of damage they could have inflicted on each other...

I guess it's that predators budget their energy usage and evaluate the risks of confrontations. A wound would probably lead to infection and death, and expending energy fighting another big predator when you could spend that energy hunting instead...
