Overview
The western yellow-bellied sand snake is a slim, fast snake occupying the drier western regions of southern Africa. It belongs to the widespread Psammophis genus of active, visually hunting sand snakes adapted to open, arid landscapes.
As with related sand snakes, it possesses mild rear-fanged venom used to overpower small prey, but it presents no significant danger to humans.
How to identify it
- Slender body, tan to grayish-brown above
- Bright yellow belly, giving the species its common name
- Large eyes with round pupils suited to daytime hunting
- Smooth scales
- Long, whip-like tail
The vivid yellow ventral coloration combined with its restricted arid western range helps distinguish it from related sand snake species.

Western yellow-bellied sand snakes are active, diurnal hunters relying on speed and sharp eyesight to catch lizards and small vertebrates, subdued with mild venom.
