How to Identify the Slender Blind Snake (Identification Guide)

Key identifying features

The slender blind snake is identified by its very thin, cylindrical, worm-like body, smooth and glossy scales, and tiny, barely visible eyes covered by translucent scales, reflecting its almost entirely underground lifestyle.

Coloration & pattern

The body is typically a uniform brown, tan, gray, or pinkish color with a glossy sheen, and generally lacks any bold pattern. The belly may be slightly paler than the back, but overall coloration is fairly uniform along the length of the body.

Head, eyes & scales

The head is small, rounded, and blunt, not clearly wider than the neck, with tiny vestigial eyes visible only as small dark spots beneath the skin. Scales are smooth, glossy, and arranged in uniform rings around the body, giving it a polished, worm-like texture that helps it move through soil.

Size & body shape

This is a very slender, small snake, typically ranging from about 15 to 30 cm (6 to 12 inches) in length, with a nearly uniform diameter from head to tail and a short, blunt tail often ending in a tiny spine.

Range & habitat where you'll see it

Slender blind snakes are found in a variety of warm regions worldwide, typically living underground in loose soil, under rocks and logs, or within termite and ant nests, and are rarely encountered above ground except after heavy rain.

How to tell it apart from look-alikes

This species can be distinguished from earthworms by its scaled body and tiny head with vestigial eyes, and from other blind or thread snakes mainly by subtle scale row counts and precise geographic range, since general body form and coloration are very similar across the group.
