Pit are one of the organs in rattlesnake that allows them to detect infrared radiation. The other organ that functions in a similar manner is their eyes.
The pit organ acts like a pin hole camera, allowing radiation to pass though its opening and eventually hitting and warming the back wall.
<em>The ability to detect infrared heat radiation enables rattlesnakes to locate its prey in any environmental condition, especially in the dark. Rattlesnake's preys are usually warm blooded, hence, the relevance of the infrared heat radiation detecting pit.</em>
