Let me rephrase the question – Do we call the Visible Spectrum that because that’s what we can see or is there something different about that part of electromagnetic spectrum (ES) that allow vision to occur. Alternately, If light is dual in nature, being both a wave and a particle, is that the same for other parts of the ES?
Which brings me to the question that I’m most curious about; would it be possible for a creature exist that can see, the same way we see, but using frequencies from other areas of the ES?

The thing that’s special about the visible part of the spectrum (and nearby frequencies that are visible to other animals but not to humans) is that [it passes through Earth’s atmosphere very well](https://i.stack.imgur.com/l6tYD.jpg). That’s why every animal with eyes sees somewhere around those wavelengths- it would be useless to see any other wavelengths because those other ones aren’t very common on Earth, so the ability to see them just didn’t evolve.
