Infrared imaging in vipers: differential responses of crotaline and viperine snakes to paired thermal targets

Pit vipers use infrared-sensitive pit organs to accurately target homeothermic prey even in the absence of visual cues. It has been suggested that other vipers, including large ambush predators of the genus Bitis, also may use radiant infrared information for predatory targeting.We compared behavioral responses of pit vipers and snakes of the viperine genus Bitis […]
