Conservation
IUCN Red List status is Least Concern due to widespread distribution, high adaptability, and large overall population size, though local populations can face threats from habitat fragmentation and urban pesticide use.
Physical Description
Light brown, grayish, or reddish-brown dorsally with a lighter mid-dorsal stripe bordered by small dark spots or dashes. The head is relatively distinct from the neck, featuring dark blotches or a collar marking behind the head. Scales are strongly keeled.
Size & Dimensions
Specimen shown appears small, likely a juvenile or a young adult approximately 20 to 25 cm. Adult typical size ranges from 23 to 33 cm, with a maximum recorded length around 52 cm.
Habitat
Highly adaptable, found in moist woodlands, fields, marshes, meadows, and heavily urbanized suburban areas. Often utilizes microhabitats offering cover such as logs, stones, leaf litter, and boards.
Diet & Feeding
Specialized diet consisting primarily of soft-bodied invertebrates such as slugs, earthworms, snails, and occasionally small amphibians. Uses an active foraging strategy in damp microhabitats.
Reproduction
Viviparous (gives birth to live young). Mating occurs in spring, and females typically give birth in late summer to a litter ranging from 3 to over 20 young, averaging around 12.
Conservation Status
IUCN Red List status is Least Concern due to widespread distribution, high adaptability, and large overall population size, though local populations can face threats from habitat fragmentation and urban pesticide use.
Cultural Significance
Acts as an important natural pest controller in suburban gardens and agricultural areas by consuming large quantities of garden pests like slugs and snails.
Notable Features
Exhibits specialized jaw adaptations allowing them to extract snails from their shells. Highly urban-tolerant, frequently appearing in suburban backyards where other snakes might be absent.
