  2. Infrared sensing in snakes - Wikipedia

    en.wikipedia.org/wiki/Infrared_sensing_in_snakes

    What is commonly called a pit organ allows these animals to essentially "see" [1] radiant heat at wavelengths between 5 and 30 μm. The more advanced infrared sense of pit vipers allows these animals to strike prey accurately even in the absence of light, and detect warm objects from several meters away.

  3. Bird vision - Wikipedia

    en.wikipedia.org/wiki/Bird_vision

    This increases the amount of light each photosensitive cell receives, allowing the bird to see better in low light conditions. [4] Owls normally have only one fovea, and that is poorly developed except in diurnal hunters like the short-eared owl. [77] Besides owls, bat hawks, frogmouths and nightjars also display good night vision.

  4. Night vision - Wikipedia

    en.wikipedia.org/wiki/Night_vision

    Active infrared night-vision combines infrared illumination of spectral range 700–1,000 nm (just over the visible spectrum of the human eye) with CCD cameras sensitive to this light. The resulting scene, which is apparently dark to a human observer, appears as a monochrome image on a normal display device. [ 15 ]

  6. Tapetum lucidum - Wikipedia

    en.wikipedia.org/wiki/Tapetum_lucidum

    When light shines into the eye of an animal having a tapetum lucidum, the pupil appears to glow. Eyeshine can be seen in many animals, in nature, and in flash photographs. In low light, a hand-held flashlight is sufficient to produce eyeshine that is visible to humans (despite their inferior night vision).

  7. Infrared sensing in vampire bats - Wikipedia

    en.wikipedia.org/wiki/Infrared_sensing_in...

    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 ...
