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]
Infrared cues from these receptors are transmitted to the brain by the trigeminal nerve, where they are used to create thermal maps of the snake's surroundings. [33] Due to the small sizes of the pit openings, typically these thermal images are low in resolution and contrast.
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]
The detection by predators and competing individuals of same species provides a strong evolutionary pressure. When active sensing is used, energy levels detected at the target are greater than those of the returning signal. Prey or predators evolved to eavesdrop on active sensing signals [citation needed]. For example, most flying insect preys ...
A nucleus has been found in the brain of vampire bats that has a similar position and similar histology to the infrared receptor of infrared-sensing snakes, [22] [23] which are the only other known vertebrates capable of detecting infrared radiation (namely boas, pythons and pit vipers). [24]
Here are some of the mot common bug, insect and spider bites you might be dealing with — and insect bite pictures to help you figure out what type of creature is responsible. Tick bites
