How to Identify the Northern Shovel-Nosed Snake (Identification Guide)
A small desert-dwelling snake distinguished by its shovel-like snout and vivid black, cream, and orange banded pattern, found across the northern Sonoran and Mojave Desert regions.

The Northern Shovel-Nosed Snake (Chionactis occipitalis) is a small, sand-adapted snake recognized by its wedge-shaped, countersunk snout designed for burrowing through loose desert sand. It has a smooth, glossy body and a bold ringed pattern that makes it one of the more visually striking small desert snakes.
Coloration & pattern
The body is marked with alternating bands of black, pale cream or yellow, and orange, forming rings or saddle-like markings around the body. The black bands are usually narrower than the light bands, and the orange bands may be faint or vivid depending on the subspecies and locality. This bright, high-contrast banding is thought to provide camouflage against dappled light and shadow on sand.
Head, eyes & scales
The head is small and only slightly distinct from the neck, an adaptation that reduces resistance during subsurface burrowing. The snout is flattened and shovel-shaped, with the lower jaw recessed beneath the upper jaw, visible as a distinct overhang when viewed in profile. Eyes are small with round pupils. The scales are smooth and polished over the entire body, which helps the snake move fluidly through sand.
Size & body shape
Adults typically measure 25 to 43 cm (10 to 17 inches). The body is slender and cylindrical, tapering evenly to a short, pointed tail, giving the snake a streamlined torpedo-like shape suited to a fossorial, sand-swimming lifestyle.
Range & habitat where you'll see it
This species is found in the Mojave and northern Sonoran Deserts of the southwestern United States, including California, Nevada, Arizona, and Utah. It favors fine, loose, sandy soils in desert flats, dunes, and washes with sparse vegetation. Being largely nocturnal and fossorial, it is rarely seen above ground during the day and is most often encountered crossing roads at night during warm months.
How to tell it apart from look-alikes
The Northern Shovel-Nosed Snake closely resembles the Southern Shovel-Nosed Snake and other Chionactis taxa; differences in band count, color saturation, and range are used to separate them. It can be confused with young banded kingsnakes or long-nosed snakes, but its distinctly flattened, countersunk snout and small, glossy, evenly cylindrical body set it apart. Its bands also stay crisp and well-defined rather than mottled or blotchy, which helps distinguish it from patchier-patterned desert species.
Frequently asked questions
What feature best identifies the Northern Shovel-Nosed Snake?
Its flattened, countersunk snout paired with bold black, cream, and orange banding running around a small glossy body.
How is it different from the Southern Shovel-Nosed Snake?
The two are very similar; they are mainly distinguished by geographic range and subtle differences in band width and coloration.
Why does it have a shovel-shaped snout?
The flattened, countersunk snout is an adaptation that lets the snake push through and burrow beneath loose desert sand efficiently.
When is this snake most likely to be seen?
It is primarily nocturnal and most often observed at night, particularly crossing roads in warm desert months.
Does its coloring change with age or region?
Band width and orange saturation vary somewhat by subspecies and locality, but the overall crisp ringed pattern remains consistent.
