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]
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.
Many empirical studies have found evidence for the theory. Primates, including humans, are able to quickly detect snakes. [6] [7] Some studies have found that humans can detect snake images before subjective visual perception. [8] However, the pre-conscious detection of snake stimuli is still under debate by the scientific community. [9]
The Haller's Organ is sensitive to heat via infrared radiation, able to detect humans or a source of 37°Celsius heat up to four meters away. [5] Ticks in the study were most attracted to infrared wavelengths of 880 nm and were found to demonstrate thermotaxis toward the source, which importantly, was disrupted by either removing the forelegs ...
