Key identifying features
The Cape Gopher Snake (Pituophis catenifer vertebralis) is a regional subspecies of gopher snake restricted to the southern Baja California peninsula, identified by its typical gopher snake blotched pattern combined with regional variation in blotch shape and background tone.
Coloration & pattern
The background color is generally tan to light brown, overlaid with a series of darker brown to blackish blotches running down the back, often somewhat elongated compared to other subspecies. Some individuals show a slightly more muted or faded pattern compared to more northern gopher snake populations, an adaptation possibly linked to local habitat conditions.
Head, eyes & scales
The head is narrow and pointed, aiding in burrowing, with round pupils typical of non-venomous colubrids. Scales are strongly keeled, giving the body a rough, matte texture shared across gopher snake subspecies.
Size & body shape
Adults typically reach 1 to 1.6 meters, generally on the smaller end for gopher snake subspecies, with a moderately thick body and tapering tail suited to its more limited peninsular range.
Range & habitat where you'll see it
This subspecies is restricted to the Cape region of southern Baja California, Mexico, inhabiting desert scrub, arroyos, and rocky terrain typical of the peninsula's arid landscape. It shelters in burrows and rock crevices, emerging to forage during cooler periods of the day.
How to tell it apart from look-alikes
Its limited geographic range in the southern Baja California peninsula is one of the most useful identification anchors, as it does not overlap with most other gopher snake subspecies. Pattern and coloring are broadly similar to related subspecies, so range and locality are key to confirming identification, along with the shared gopher snake traits of round pupils and keeled scales.
