Why don't Orcas attack humans?

These aquachads have teeth that would give batman nightmares and are the absolute apex predators of three quarters of the planet (with the other 25% being *land*), and prey on things as fearsome as *Great White sharks,* which *do* eat humans, even if very rarely. And yet, whenever the subject of orca predation is discussed on documentaries and such, it's always mentioned that no wild Orca has ever killed and eaten a human **even once in all of recorded history**. Why is that?

Potentially partly because orca are highly selective hunters? 

For example some pods exclusively hunt fish, others hunt dolphins, others hunt seals.

Not just that, different pods have their own preferred hinting techniques.

Like that famous video of orcas beaching to catch seal pups is behaviour only known from a single pod. Orca in other parts of the world don't hunt seals like that.

Orca in New Zealand specialize in hunting stingray by chasing them into shallow bays or trapping them against rock walls.

These strategies seem to be passed down through the generations within a pod, which is why they have such distinct hunting techniques.

So maybe orca don't hunt humans because they were never taught to.
