What anatomical feature provides definitive confirmation of pit viper classification over Gopher snakes (*Pituophis* species)?
Answer
The presence of loreal pits situated between the eye and nostril
While head shape similarity can exist between *Crotalus oreganus* and mimics like Gopher snakes (*Pituophis* species), the presence of loreal pits offers a definitive physical confirmation of pit viper classification. These pits are specialized, deeply recessed heat-sensing organs located solely on the face of pit vipers, positioned precisely between the eye and the nostril. Gopher snakes lack this specific facial structure, presenting a smooth profile in that area. Therefore, identifying these pits provides a reliable physical test for the presence of venom apparatus associated with the pit viper group, which is safer than relying on pupil shape or general head contour.
