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]
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 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.
Re-narrated Horizon episode, first aired in the UK in 1972. [4]We give you a behind-the-scenes look at the making of a nature film. Oxford Scientific Films Unit shows how it tackles such problems as filming a wood wasp laying its eggs inside trees, the hatching of a chick and the courtship rituals of the stickleback.
Vampire bats have developed a specialized system using infrared-sensitive receptors on their nose-leaf to prey on homeothermic (warm-blooded) vertebrates. [1] Trigeminal nerve fibers that innervate these IR-sensitive receptors may be involved in detection of infrared thermal radiation emitted by their prey. This may aid bats in locating blood ...
