What specialized thermoreceptive organ defines the subfamily Crotalinae, placing Crotalus atrox within it?
Answer
A visible opening located between the eye and the nostril.
The defining characteristic of the subfamily Crotalinae is the development of the loreal pit. This is a highly specialized thermoreceptive organ, appearing as a visible opening situated between the snake's eye and its nostril on each side of the head. This adaptation allows the snake, such as the Western Diamondback Rattlesnake, to sense the infrared radiation emitted by warm-blooded prey, enabling it to accurately strike targets even in conditions of total darkness, which is crucial for its nocturnal ambush predator strategy.
