How to Identify the Desert Blind Snake (Identification Guide)

Key identifying features

The Desert Blind Snake is a small, cylindrical, worm-like snake adapted for a subterranean lifestyle. Its defining features include a uniformly smooth, shiny body, a blunt head and tail that look almost identical at a glance, and eyes reduced to small dark spots beneath translucent scales rather than functional, visible eyes. These traits together produce an animal that looks more like an earthworm than a typical snake.

Coloration & pattern

Coloration is generally uniform across the body, ranging from pale pink and tan to purplish-brown or silvery-gray depending on the individual and light conditions. There is little to no discernible pattern, blotching, or banding; the coloration is typically even from head to tail. The scales often have an iridescent or pearly sheen that becomes more apparent in direct light, a useful field clue distinguishing it from true worms.

Head, eyes & scales

The head is small, rounded, and barely distinct from the rest of the body, ending in a blunt snout used for pushing through soil. Eyes are vestigial, appearing only as tiny dark dots beneath the head scales, functional mainly for detecting light and dark rather than forming images. Scales are smooth, small, and uniform in size all around the body (unlike most snakes, which have larger belly scales), giving the body a consistent cylindrical cross-section.

Size & body shape

Desert Blind Snakes are very small, usually 15-30 cm (6-12 inches) long, with a thread-like to pencil-thin diameter that remains nearly constant along the entire body. The tail ends in a small, blunt spine-like tip rather than tapering to a fine point, which can help distinguish the tail end from the head end on close inspection. The body shows no narrowing at the neck, appearing as a continuous tube.

Range & habitat where you'll see it

This species inhabits arid and semi-arid regions, favoring loose, sandy, or friable soils where it can burrow easily. It is almost entirely fossorial, spending the vast majority of its time underground and surfacing mainly after rain, at night, or when soil is disturbed. Encounters typically happen by chance, such as when digging, moving rocks, or after heavy rainfall drives it to the surface.

How to tell it apart from look-alikes

The most common confusion is with earthworms, but blind snakes have smooth, scaled skin with a subtle sheen, a distinct (if tiny) head, and no segmented ring pattern. Compared to other small fossorial snakes like worm snakes, blind snakes lack visible functional eyes and have a more uniformly cylindrical, less tapered body. Juvenile colubrid snakes are generally more patterned, longer, and have clearly visible eyes, distinguishing them readily from the nearly eyeless blind snake.
