Conservation
IUCN Red List: Least Concern. They are highly resilient to habitat fragmentation and thrive in human-altered landscapes.
Physical Description
Small, slender snake with a base color ranging from light brown to gray or almost black (as seen in this darker specimen). It typically features two rows of small dark spots bordering a lighter central dorsal stripe. The head is relatively small with a dark spot below the eye and on the temporal region. Scales are keeled (rough to the touch).
Size & Dimensions
The specimen in the container appears to be an adult or sub-adult, roughly 8-12 inches (20-30 cm) long. Typical adult size for the species is 9 to 13 inches (23-33 cm), with a maximum record of about 20 inches.
Habitat
Highly adaptable; found in woodlands, wetlands, and grasslands. It is notably 'synanthropic,' commonly inhabiting urban and suburban areas including backyards, vacant lots, and under debris in gardens. They prefer moist soil and microhabitats under rocks or logs.
Diet & Feeding
Specialized diet consisting primarily of soft-bodied invertebrates like earthworms, slugs, and snails. They possess specialized teeth and jaw adaptations to extract snails from their shells.
Reproduction
Viviparous (gives birth to live young rather than laying eggs). Litters typically range from 3 to 40 young, born in late summer (July–September).
Conservation Status
IUCN Red List: Least Concern. They are highly resilient to habitat fragmentation and thrive in human-altered landscapes.
Cultural Significance
Crucial ecological role as natural pest control in gardens, as they consume large quantities of slugs and snails that damage ornamental plants and crops.
Notable Features
One of the most common snakes in metropolitan areas, often living entire lives in urban gardens without being detected by residents due to their secretive nature and diminutive size.
