That is very interesting!
Unfortunately this idea is impractical for warm-blooded creatures, whose body temperature is strictly regulated... at least until it isn't, at which point they're no longer much good for seeing photons because they're busy being treated for hypothermia.

- kurtosis 18y agoso I dug up the reference on this in case you are interested and have access to nature. Google scholar has pointers to the pdf Aho AC et. al. "Low retinal noise in animals with low body temperature allows high visual sensitivity."
