Key identifying features
The Common Mole Snake (Pseudaspis cana) is a large, powerful, non-venomous snake found throughout southern Africa. It is identified by its robust, muscular body, small head barely distinct from the neck, and generally uniform coloration, all adaptations suited to its semi-fossorial habits and diet of burrowing rodents.
Coloration & pattern
Coloration varies considerably by region and age but is typically uniform, ranging from grayish-brown, olive-brown, reddish-brown, to black in some populations, particularly older individuals. Juveniles often show a more patterned appearance, with darker blotches or speckling that fades as the snake matures into a more solid adult coloration. The belly is usually a lighter shade of the dorsal color, sometimes with a yellowish tinge.
Head, eyes & scales
The head is small and narrow relative to the thick body, with a rounded snout suited for pushing into rodent burrows. Eyes are relatively small with round pupils. Scales are smooth, giving the body a sleek surface that helps the snake move efficiently through burrows and loose soil.
Size & body shape
The Common Mole Snake is one of the larger snake species in southern Africa, with adults commonly reaching 1.5 to 2 meters, and exceptional individuals recorded up to nearly 2.5 meters. The body is thick and muscular, notably more robust than many other snakes of similar length, reflecting its powerful burrowing lifestyle and largely rodent-based diet.
Range & habitat where you'll see it
This species is widespread across South Africa, Namibia, Botswana, and neighboring regions, occupying a wide range of habitats including fynbos, grassland, savanna, semi-desert, and agricultural land. It is often found in or near rodent burrows and is active both during the day and at dusk, frequently encountered basking or moving across open ground.
How to tell it apart from look-alikes
Its thick, muscular body and small head lacking a triangular shape distinguish it from venomous vipers and cobras, which have broader heads or hoods. The uniform coloration of adults, especially in darker individuals, can lead to confusion with other large uniformly colored snakes, but the Common Mole Snake's stout build, small eyes, and rounded, non-triangular head are reliable identification features.
