*[[Snake Special Senses|Heat sensory pits]] (infrared-sensitive receptors) - are deep grooves between the nares and the [[Snake Eye|eye]] of [[Pit viper|pit vipers]], [[Pythoninae|pythons]] and some [[Boidae|boas]] which allow them to 'see' the radiated heat of their prey.  These pits can also be found on the upper lip, just below the nares, termed 'labial pits'.
