What senses would you use, or need to invent, if you were writing from the point of view (POV) of a mythical creature?

If I was writing this scene from the dragon’s POV, I would write that it had the same organ some snakes have on their faces to detect heat. Would the dragon be able to see well in the dark? Would the dark look like dark to it? Since it doesn’t have ears made of cartilage sticking our from its head, maybe it doesn’t hear well. If it breathes fire, and your readers will be disappointed if it doesn’t breathe something, it could notice when heat is building up inside the organ that generates the fire.

What if you wrote from a centaur’s POV? I was thinking about that because I took riding lessons. My teacher told me that horses are nervous about their feet, especially the back ones, because they can’t see them. Perhaps a centaur can’t see them well either, and a back hoof got stuck in a trap, what he sense?

What mythical creature can you think of with an unusual sense?
