Key identifying features
The Scarlet Snake is a small, non-venomous, secretive colubrid snake known for its bold tricolor banding pattern of red, black, and cream or yellow. It is frequently confused with the venomous coral snake due to overlapping colors, but key differences in band order, head shape, and belly color allow reliable identification.
Coloration & pattern
The body shows a series of red, black, and cream, yellow, or white bands or saddles running across the back, though unlike the coral snake, the bands typically do not fully encircle the belly, and the belly itself is usually plain white or cream rather than banded. The red bands are often bordered by black, and importantly, in this species red bands typically touch black bands rather than yellow, a pattern opposite to that of the venomous coral snake in regions where both occur. The snout is often marked with red or has a reddish tint.
Head, eyes & scales
The head is small, narrow, and not distinct from the neck, quite different from the broad triangular head of pit vipers. The eyes are small with round pupils. Scales are smooth, giving the body a glossy appearance. The snout tends to be somewhat pointed, an adaptation associated with its burrowing habits.
Size & body shape
This is a small, slender snake, with adults typically reaching only about 35 to 50 centimeters in total length. The body is smooth and cylindrical, well suited to burrowing through loose soil and leaf litter.
Range & habitat where you'll see it
The Scarlet Snake is found in the southeastern and south-central United States, typically in sandy or well-drained soils within pine forests, hardwood forests, and agricultural edges. It is highly secretive and fossorial, spending most of its time underground or under surface debris, and is rarely seen above ground except at night or after rain.
How to tell it apart from look-alikes
The classic distinguishing feature between this species and the venomous coral snake is the relationship between the red and black bands: in the Scarlet Snake, red bands border black bands, whereas in the coral snake red bands border yellow bands, summarized in the well-known regional rhyme relating red and black versus red and yellow banding. Additionally, the Scarlet Snake's plain, unbanded white belly and bands that do not fully encircle the body distinguish it from the coral snake, whose bands wrap completely around the body including the belly. The Scarlet Snake's smaller size, pointed snout, and secretive burrowing habits further support identification.
