Pit vipers detect their warm-blooded prey using specialized heat-sensing pits located between their eyes and nostrils. These pits contain a membrane that is highly sensitive to infrared radiation (heat). This allows the snakes to "see" an image of their prey in the dark, similar to how a thermal camera works. | Eureka HN B
