The ability to sense infrared thermal radiation evolved independently in three different groups of snakes, consisting of the families of Boidae (boas), Pythonidae (pythons), and the subfamily Crotalinae (pit vipers). What is commonly called a pit organ allows these animals to essentially "see" [1] radiant heat at wavelengths between 5 and 30 ...
The snakes' face has a pair of holes, or pits, lined with temperature sensors. The sensors indirectly detect infrared radiation by its heating effect on the skin inside the pit. They can work out which part of the pit is hottest, and therefore the direction of the heat source, which could be a warm-blooded prey animal.
Studies have indicated these snakes learn to improve their strike accuracy over time. [11] Many temperate species of pit vipers (e.g. most rattlesnakes) congregate in sheltered areas or "dens" to overwinter (brumate, see hibernation), the snakes benefiting from the combined heat. In cool temperatures and while pregnant, pit vipers also bask on ...
Finding just a snake skin, a really big snake skin. When the temperatures begin to drop, snakes go into a state called brumation . This event acts as a type of hibernation for cold-blooded animals.

Even in the fall and winter, snakes will periodically come out in the daytime when temperatures are higher. You could even see them at dawn or dusk on especially warm days, Hall said.
