Nice article.

I was unaware that heat sensing pits in snakes were so sensitive to such a spectrum of wavelength... However, how it applies here needs to be kept in mind in the interpretation of their results.

The pits are receptors... They detect things. Their prey items are not emmitting x-rays, gamma rays, ultraviolet, whatever radation that you want to talk about. The prety is mainly emmitting infra red radiation. The other wavelengths discussed are not being emmitted by the prey item, so whether or not these wavelengths can be detected is moot. As mentioned earlier, infrared doesn't have the penetrating power to be seen through appreciable solids such as skin, fat, connective tissue etc.
