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 ...
The higher the altitude, the less dense the atmosphere and the less infrared radiation it absorbs - especially at longer wavelengths. The effect of reduction in friction between air and aircraft does not compensate for the better transmission of infrared radiation. Therefore, infrared detection ranges are longer at high altitudes.
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 ]

Two new wolf packs have been spotted in Northern California, which shows a continued resurgence of the species a century after they disappeared from the Golden State.
