Where are the heat-sensing loreal pits located on pit vipers?

Answer

Between the eye and the nostril

The defining characteristic of pit vipers, or the Crotalinae subfamily, is the loreal pit organ, which is positioned on the side of the head specifically between the eye and the nostril. This anatomical placement allows the snake to triangulate heat sources from prey with high precision, aiding in hunting and environmental awareness.
