Key identifying features

The Mole Viper is identified by its highly cylindrical, glossy body adapted for burrowing, a small head barely distinct from the neck, and reduced, tiny eyes that reflect its largely subterranean lifestyle. Unlike typical vipers, its head shape does not show the broad triangular flare associated with many viper species.

Coloration & pattern

The body is typically uniform in coloration, ranging from dark brown to black or purplish-black, often with little to no distinct pattern, consistent with a fossorial lifestyle where camouflage against surface predators is less relevant. Some individuals may show a slightly paler venter compared to the dorsal surface.

Head, eyes & scales

The head is small, somewhat blunt or shovel-shaped, an adaptation for pushing through soil, and is not markedly wider than the neck. Eyes are notably small and reduced, reflecting limited reliance on vision. Scales are smooth and glossy, aiding smooth movement through soil and leaf litter.

Size & body shape

This is a small to medium-sized snake with a uniformly cylindrical, worm-like or burrowing body shape, showing minimal tapering along its length and a short, blunt tail.

Range & habitat where you'll see it

Found in parts of sub-Saharan Africa, this species spends much of its time underground or under surface debris such as logs, rocks, and leaf litter, making surface encounters relatively uncommon compared to more visible viper species.

How to tell it apart from look-alikes

Because of its cylindrical, small-headed, burrowing body plan, this species can resemble certain nonvenomous burrowing snakes at a glance. Key distinguishing features include its uniform dark coloration, small reduced eyes, and shovel-like head shape adapted for digging, differing markedly from the broad triangular heads of surface-dwelling vipers.

Frequently asked questions

Why does this snake have such small eyes?

Its small, reduced eyes reflect a largely burrowing, underground lifestyle where vision is less important than in surface-dwelling species.

Does this snake have a typical triangular viper head?

No, its head is small, blunt, and shovel-shaped for burrowing, unlike the broad triangular heads seen in many surface vipers.

What color is this snake usually?

It is typically uniform dark brown to black or purplish-black, often lacking a distinct pattern.

Where is this snake most likely to be encountered?

Underground or under surface debris like logs, rocks, and leaf litter in parts of sub-Saharan Africa, making direct surface sightings uncommon.
