    Like all pit vipers, rattlesnakes have two organs that can sense radiation; their eyes and a set of heat-sensing "pits" on their faces that enable them to locate prey and move towards it, based on the prey's thermal radiation signature. These pits have a relatively short effective range of about 1 ft (0.30 m) but give the rattlesnake a distinct ...

    The snakes also feed from within on energy-rich lipid stores. The most interesting finding was the snakes grew during the study, indicating while the snake's mass was shrinking, it was putting its resources into skeletal muscles and bone.

  8. Infrared sensing in snakes - Wikipedia

    en.wikipedia.org/wiki/Infrared_sensing_in_snakes

    Infrared sensing snakes use pit organs extensively to detect and target warm-blooded prey such as rodents and birds. Blind or blindfolded rattlesnakes can strike prey accurately in the complete absence of visible light, [ 13 ] [ 14 ] though it does not appear that they assess prey animals based on their body temperature. [ 15 ]
