Mexican Hognose Snake

How to identify

A smallish snake reaching 16-25 inches in length. It has a thick body and small, stubby head with an upturned scale at the tip of its snout. It has keeled scales with a background color of light grey or tan, adorned with alternating rows of circular blotches with undefined edges. The blotches on the sides of the body are generally darker than those down the center of the back. It typically has a dark mask from the corners of the mouth, through the eyes, and across the center of the face, with a thin light band between the eyes, separating the center of the dark mask into 2 bands. Just behind the mask, it has 3 dark patches on the back of its head and neck. Ventral scales are dark grey to black with random yellow patches all over. When threatened, this snake will readily hiss, open its mouth and drastically flatten its head and neck to appear wider. It will also play dead by dramatically flipping onto its back and opening its mouth with its tongue hanging out.
