Whales probably don't know what apes are, I mean how many live near an ocean?

But we are mammals like them and they'd probably realize the similarity given that we need air. Maybe they'd consider us some kind of killer land whale?

They know what humans are, and certainly have some way of calling us.

I'd imagine they don't consider us any similar to them. But they know those indestructible whale-like surface gliders are shocking full of us, and that we can kill a whale with way more easiness than them.
