Detailed explanation-1: -Heat Gene. Scientists have long known that this group of venomous vipers-which include species of lanceheads, moccasins, and bushmasters-have the ability to sense infrared at a distance of about 1 meter.
Detailed explanation-2: -Venomous pit vipers detect warm-blooded prey through their ability to sense infrared (750 nm – 1 mm wavelength) radiation. Superimposition of thermal and visual images within the snake’s brain enables it to track animals with great precision and speed.
Detailed explanation-3: -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, though it does not appear that they assess prey animals based on their body temperature.
Detailed explanation-4: -Pit vipers detect infrared radiation by means of temperature contrasts created on their pit organ membranes. Signals from pit organs integrate with visual signals in the optic tectum, leading to the conjecture that the facial pits operate as an extension of the visual system.
