Conservation
Least Concern (IUCN). They are common and face no major threats, though they are often killed by gardeners who mistake them for venomous species.
Physical Description
Small, stout snake with a small, rounded head barely distinct from the neck. Coloration is typically olive-brown to reddish-brown with a faint dark vertebral stripe and dark-edged lateral scales. Belly is usually yellowish-white with dark spots. Scales are smooth.
Size & Dimensions
Specimen appears to be an adult of approximately 25-30 cm. The species typically ranges from 20 to 35 cm, with a maximum recorded length of about 45 cm.
Habitat
Found in moist savannas, grasslands, and suburban gardens. They prefer damp areas with plenty of ground cover (leaf litter, logs, or stones) where their prey is abundant.
Diet & Feeding
Specialized feeder on terrestrial mollusks (slugs and snails). They use their teeth to grip the slippery prey and often swallow them whole or extract snails from shells.
Reproduction
Viviparous (gives birth to live young). A female can produce 6 to 22 young in late summer, usually between January and March in southern Africa.
Look-alikes
Sometimes confused with the Common Brown House Snake (Boaedon capensis) or juvenile Herald Snakes (Crotaphopeltis hotamboeia). It can be distinguished by its significantly smaller head and more robust, 'tubular' body shape.
Conservation Status
Least Concern (IUCN). They are common and face no major threats, though they are often killed by gardeners who mistake them for venomous species.
Cultural Significance
Known as a 'gardener's friend' due to its diet of garden pests (slugs). In some regions, they are wrongly feared as 'night adders' due to their dark coloration and terrestrial habits.
Notable Features
Notable for their extreme specialization in eating slugs and snails. They are one of the few snake species that are almost entirely 'bite-less' in their defensive repertoire.
