What is the primary function of the upturned rostral scale on *H. nasicus*?
Answer
It acts as a plow, enabling efficient burrowing into loose substrates like sand or loose soil.
The most prominent morphological feature of *H. nasicus* is its highly specialized, upturned rostral scale located at the tip of its nose. This structure functions essentially as a finely tuned agricultural implement or plow. Its evolutionary purpose is to facilitate the snake's movement and efficient burrowing through soft or loose substrates, such as sandy soils or loose dirt. This specialized digging apparatus grants the Western Hognose a significant advantage in its typical environment, which often includes sandy prairies, allowing it to hunt fossorial prey or seek thermal refuge underground.
