Duberria Lutrix

Duberria lutrix, widely known by the common name Common Slug-eater, is a small colubrid snake distributed across sub-Saharan Africa. It is one of the best-studied members of its genus due to its distinctive dietary specialization and frequent occurrence around human dwellings and gardens.

This species is entirely non-venomous and poses no danger to people, being valued instead for its role in controlling garden mollusk populations.

• Small, cylindrical body, generally under 40 cm
• Reddish-brown to grayish dorsal color, sometimes with a faint pale stripe along the spine
• Smooth, glossy scales
• Small, blunt head not distinct from the neck
• Round pupils

Identified by its small size, smooth uniform coloration, and characteristic docile behavior, along with a jaw structure specialized for extracting snails from their shells.

Occurs across moist grassland, gardens, forest edges, and agricultural areas throughout sub-Saharan Africa, from South Africa north into East and Central Africa. Thrives in areas with abundant leaf litter, moisture, and mollusk prey.

Mostly crepuscular or nocturnal, becoming more active on damp or rainy days when slugs and snails are abundant. Extremely docile, it typically coils tightly rather than striking when disturbed.

Feeds exclusively on slugs and snails, extracting them from their shells with specialized jaws. Reproduction is live-bearing (ovoviviparous), with small litters produced annually.
