Key identifying features
The saddled leaf-nosed snake (Phyllorhynchus browni) is identified by its enlarged, upturned, leaf-shaped rostral scale combined with a series of large, dark, well-defined saddle-shaped blotches running down its back, bolder and more numerous than in its close relative the spotted leaf-nosed snake.
Coloration & pattern
The base color is pale tan, cream, or light brown. Down the back runs a row of large, dark brown to chocolate saddle-shaped blotches with fairly sharp edges, often alternating with smaller spots along the sides. The pattern is more contrasted and continuous than the sparse, small spotting of the spotted leaf-nosed snake, giving this species a more strongly marked appearance overall.
Head, eyes & scales
As with all leaf-nosed snakes, the standout feature is the enlarged, upturned, leaf-shaped scale at the tip of the snout, adapted for digging through loose soil. The head is only slightly wider than the neck, and the eyes are large with vertically elliptical pupils suited to nocturnal activity. Scales are smooth and glossy.
Size & body shape
Adults typically measure 30 to 53 cm (12 to 21 inches), making this species slightly larger on average than the spotted leaf-nosed snake. The body is slender and cylindrical, adapted for moving through sand and loose desert soils.
Range & habitat where you'll see it
This species occurs in southern Arizona and northwestern Mexico, favoring rocky desert foothills, canyons, and washes, often at slightly higher elevations or rockier terrain than the spotted leaf-nosed snake. It is nocturnal and rarely seen during the day, most often found crossing roads on warm nights or under surface debris.
How to tell it apart from look-alikes
The primary distinction from the spotted leaf-nosed snake is pattern boldness: saddled leaf-nosed snakes have larger, darker, more closely spaced saddle blotches, while spotted leaf-nosed snakes show smaller, more scattered, fainter spots. Both share the diagnostic upturned leaf-shaped nose scale, which immediately separates either species from glossy snakes, gopher snakes, or ground snakes, none of which have this specialized snout structure.
