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.
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 ...
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 ]
Naturally, Australian researchers decided to study their native animals under the same light, according to ABC. Scientists have discovered that wombats, platypi and other Australian mammals glow ...
The popular belief that the common goldfish is the only animal that can see both infrared and ultraviolet light [38] is incorrect, because goldfish cannot see infrared light. [ 39 ] Invertebrates
There are two sorts of light receptors in a bird's eye, rods and cones. Rods, which contain the visual pigment rhodopsin are better for night vision because they are sensitive to small quantities of light. Cones detect specific colours (or wavelengths) of light, so they are more important to colour-orientated animals such as birds. [25]
Researchers compressed infrared light to 10% of its wavelength using a thin strontium titanate film, paving the way for advanced infrared imaging.
A mutation of the opsin on the SWS-1 pigment allows some vertebrates to absorb UV light (≈360 nm), so they can see objects that reflect UV light. [22] A wide range of fish species has developed and maintained this visual trait throughout evolution, suggesting it is advantageous.
