Which specific head features contribute to the alert appearance noted by observers?
Answer
A snout that is typically rounded and relatively large eyes.
The head structure plays a role in the overall visual impression observers form of the Western Rat Snake's demeanor. Key features contributing to its alert presentation include a snout shape that is generally rounded. Additionally, the species is noted for possessing relatively large eyes. Although the head might become less distinctly separated from the neck in very large adults, these features, combined with the snake's known agility across various surfaces, contribute to the perception of alertness.
