Weird Ways Animals Communicate in the Wild

6. The Infrared Communication of Pit Vipers

Pit vipers, including rattlesnakes and copperheads, possess a unique sensory adaptation that allows them to detect infrared radiation. This ability enables them to "see" the heat signatures of their prey, even in complete darkness. While primarily used for hunting, this infrared detection also plays a role in communication, particularly during mating and territorial disputes. By sensing the thermal cues of other animals, pit vipers can effectively navigate their environment and make strategic decisions about when to strike or retreat.
