Besides the prominent rostral scale, what facial marking is specifically noted on some Western Hognose Snakes?
Answer
A dark line running through the eye
In addition to the specialized upturned rostral scale, other facial markings can be present on the Western Hognose Snake, offering further identification clues. Several sources specifically note the presence of a dark line that runs directly through the eye area. This stripe functions as a disruptive pattern, helping to break up the snake's profile, especially when it is attempting to remain motionless and relying on camouflage when viewed head-on. While the overall pattern complexity varies, the presence of this dark eye stripe is mentioned as a specific facial feature sometimes observed in individuals of this species.
