Key identifying features
The stripe-bellied sand snake is a slender, fast-moving species distinguished by its brightly marked underside, where a yellowish belly is bordered along each side by a dark, well-defined stripe running much of the body's length. Combined with its typical sand snake build and coloring, this striped ventral surface is the most diagnostic feature for confirming identification.
Coloration & pattern
Dorsally, this species shows a pale to olive-brown or grayish background, usually marked with fine dark longitudinal stripes and pale streaks running along the back. The most distinctive feature, however, lies on the underside: the belly is yellowish or cream and carries a dark, sharply defined stripe along each side, running from near the throat toward the tail and clearly visible when the snake is viewed from below or when it moves.
Head, eyes & scales
The head is narrow and elongated, blending into the neck without a pronounced constriction, and the snout is somewhat pointed. Eyes are large with round pupils, typical of an actively hunting, diurnal sand snake. Scales are smooth, giving the body an overall glossy appearance.
Size & body shape
Adults commonly reach around 60 to 100 centimeters or more in length, with a slim, whip-like body and a long tapering tail that aids rapid locomotion. The build closely resembles other sand snakes, emphasizing speed and agility over bulk.
Range & habitat where you'll see it
This species is found in savanna and bushveld regions of central and southern Africa, inhabiting open woodland, sandy flats, and scrubland with sparse vegetation. It is diurnal, actively foraging during the day for lizards and other small prey, and retreats to burrows, rock crevices, or vegetation cover when not active.
How to tell it apart from look-alikes
While many sand snakes share a similar slender build and striped dorsal coloration, the distinct dark stripe along each side of the yellowish belly is the clearest way to separate the stripe-bellied sand snake from related species that typically have a plainer or unmarked underside. When the dorsal pattern alone is ambiguous, checking the underside for these paired ventral stripes offers a reliable confirmation.
