Conservation
IUCN Red List status is Least Concern. Widely distributed and adaptable to human-altered environments, though local populations can be threatened by habitat destruction and intentional killing.
Physical Description
Small-bodied snake with brown, gray, or reddish-brown dorsal coloration, typically featuring a lighter mid-dorsal stripe bordered by small dark spots or dashes. The head is relatively small and distinct from the neck, with dark markings on the side of the head, and the scales are keeled.
Size & Dimensions
The pictured specimen appears to be around 25 to 30 cm long. Adults typically range from 20 to 38 cm (8 to 15 inches) in total length, with a maximum recorded length of about 52 cm.
Habitat
Found in a wide variety of habitats including deciduous forests, open fields, wetlands, and heavily urbanized areas like suburban gardens and parks. Prefers moist microhabitats under rocks, logs, bark, and debris.
Diet & Feeding
Specialized feeder focusing primarily on soft-bodied invertebrates, with a strong dietary preference for slugs, snails, and earthworms. Hunts actively by foraging through leaf litter and under cover objects.
Reproduction
Viviparous (gives birth to live young rather than laying eggs). Mating occurs in the spring, and females typically give birth in late summer to a litter ranging from 3 to 20 or more young.
Conservation Status
IUCN Red List status is Least Concern. Widely distributed and adaptable to human-altered environments, though local populations can be threatened by habitat destruction and intentional killing.
Cultural Significance
Acts as an important natural pest controller in gardens and urban ecosystems by consuming large numbers of slugs, snails, and insects that can damage plants.
Notable Features
Remarkably tolerant of urban environments, often thriving in city parks and suburban backyards where larger snakes have been extirpated. Specialized jaw structure allows them to extract snails efficiently from their shells.
