Overview

The stripe-bellied sand snake is a slender, fast-moving snake distributed widely across savanna regions of southern and East Africa. It is one of the more commonly encountered members of the Psammophis genus, known collectively for their speed and active hunting style.

This species carries mild rear-fanged venom for subduing prey, but it is not considered dangerous to humans and typically flees rather than confronts when encountered.

How to identify it

  • Slender body, olive to grayish-brown above with pale lateral stripes
  • Distinctive dark stripes running along a yellowish or cream-colored belly, giving rise to its common name
  • Large eyes with round pupils
  • Smooth scales
  • Long, tapering tail

The striped belly pattern, visible from below, is the most distinguishing trait among sand snakes.

Habitat & range

This species is widespread across savanna, open woodland, and grassland habitats of southern and East Africa, often found in areas with scattered cover such as termite mounds, rock piles, and low vegetation.

Behavior, diet & reproduction

Stripe-bellied sand snakes are highly active by day, using speed and sharp eyesight to hunt lizards, small mammals, and occasionally birds, which they subdue with mild venom. They are quick to flee at high speed when disturbed, rarely standing their ground. Reproduction is oviparous, with clutches of eggs laid in warm, sheltered locations.
