Besides the pointed snout, what visual trait helps confirm the H. nasicus species identification in the field?
Answer
Distinct dark blotches or saddles along its back
While the pointed snout is the key identifier for the genus *Heterodon*, confirming the specific species designation as *H. nasicus* requires noting patterns that distinguish it from close relatives like the Eastern Hognose. The most readily observable specific trait mentioned for *H. nasicus* is the presence of distinct dark blotches or saddles that run along its dorsal surface. Experienced observers, particularly those studying populations in areas like the Great Plains or Mountain West, use this combination of the specialized snout morphology and this specific pattern of dorsal markings as the fastest way to visually confirm the species identity without relying on complex genetic analysis.
