It's been decades since my physics classes and this question occurred to me while watching an educational program on TV. I may not have the technical terms exactly right.

Visible light is composed of electromagnetic waves. It is also emitted as photons. And it is a small part of the EM spectrum. Do other areas of the EM spectrum also emit photons?

Just a question to ponder

 

Do other areas of the EM spectrum also emit photons?

Yes.
There's nothing special about visible light photons. It's just the spectrum that easy for us to detect.
All EM waves from the lowest to the highest frequencies are photons.

 

If radio emissions were common on this planet our eyes would have evolved to see in the radio spectrum.

Unfortunately, you can't resolve anything smaller than half a wavelength, so you'd need to be seeing with frequencies >600GHz to be any use.

Thus the eye evolved for peak sensitivity near the peak of the solar spectrum (below):

Coincidentally, I think it would be difficult to devise a biological sensor for good sensitivity much outside those wavelengths.
Shorter wavelengths (e.g. UV) can cause biological damage, and longer wavelengths (IR) have reduced sensitivity due to the black body radiation at biological temperatures.
Of course many creatures, besides most mammals, have evolved some sensitivity to near UV,

 

The IR sensor on our bodies is our skin. A somewhat directional sensor if we manipulate our bodies.

IR exposure often produces a sensation of heat when humans come in contact with it, it is not identical to heat. IR is a form of energy that when absorbed by water molecules (in the skin) is converted to kinetic energy—this kinetic energy is then perceived as heat.7 This method of heat transfer is not to be confused with conduction in which atoms come in direct contact with each other and kinetic energy is transferred from higher energy atoms to lower energy atoms; an example of this is the heat sensation felt when touching hot metal. Convection represents yet another distinct method of heat transfer in which heat is transferred by a liquid or gas in motion—such as when hot air rises, for example.
