The ability to sense infrared thermal radiation evolved independently in three different groups of snakes, consisting of the families of Boidae (boas), Pythonidae (pythons), and the subfamily Crotalinae (pit vipers). What is commonly called a pit organ allows these animals to essentially "see" [1] radiant heat at wavelengths between 5 and 30 ...
The snakes' face has a pair of holes, or pits, lined with temperature sensors. The sensors indirectly detect infrared radiation by its heating effect on the skin inside the pit. They can work out which part of the pit is hottest, and therefore the direction of the heat source, which could be a warm-blooded prey animal.
Activation of TRPV1-S channels in the TG may then suggest a similar mechanism (as seen in IR-sensing snakes) for how infrared sensing may work in vampire bats. Trigeminal nerves which innervate specialized temperature sensitive receptors on the nose-leaf may in turn activate TRPV1-S channels in the TG in response to infrared thermal radiation. [5]
When snakes do eat invertebrates, they are often eating dangerous things like venomous centipedes and scorpions, or slimy, noxious snails or slugs," Rabosky said.
Studies have indicated these snakes learn to improve their strike accuracy over time. [11] Many temperate species of pit vipers (e.g. most rattlesnakes) congregate in sheltered areas or "dens" to overwinter (brumate, see hibernation), the snakes benefiting from the combined heat. In cool temperatures and while pregnant, pit vipers also bask on ...
Appearance: These snakes are the smallest rattlesnakes, ranging from 16-23 inches long. Pigmy rattlesnakes have black spots with red or orange stripes all the way down its body.
The loreal pit is the deep depression, or fossa, in the loreal area on either side of the head in pit vipers (crotaline snakes). The area is located behind the nostril and in front of the eye, but below the line that runs between the centers of each. It is the external opening to an extremely sensitive infrared detecting organ.
Snakes are cold-blooded, meaning they cannot regulate their own body temperatures like humans or other warm-blooded animals. A snake’s body temperature changes with the outside temperatures.
