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]
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 ...
Lynne A. Isbell (born 1955) is an American ethologist and primatologist, professor of anthropology at the University of California, Davis.. Isbell has served as president of the American Society of Primatologists and is the originator of the snake detection theory, which suggests that snakes have contributed to the evolution of the visual system of primates.
Infrared vision is the capability of biological or artificial systems to detect infrared radiation. The terms thermal vision and thermal imaging [ 1 ] [ 2 ] are also commonly used in this context since infrared emissions from a body are directly related to their temperature: hotter objects emit more energy in the infrared spectrum than colder ones.

No, it’s admittedly not the prettiest thing to serve to guests, but if you’re looking to treat company to a nostalgic and delicious winter dinner that won’t require a whole lot of effort or ...
An infrared detector is a detector that reacts to infrared (IR) radiation. The two main types of detectors are thermal and photonic ( photodetectors ). The thermal effects of the incident IR radiation can be followed through many temperature dependent phenomena. [ 2 ]
