Venomous Status
Non-venomous
Danger Level
Harmless - poses no threat to humans or pets; bites are extremely rare and the teeth are too small to cause significant injury.
Geographic Range
Widely distributed across North America, ranging from Southern Canada (Ontario, Quebec) through the Eastern and Central United States, and south into Mexico and Central America as far as Honduras.
Conservation Status
Least Concern (IUCN). Extremely resilient to human disturbance and common throughout its range.
Physical Description
Small, slender snake typically brown to greyish-brown. Features a lighter central dorsal stripe bordered by two rows of small black spots. The head is relatively small with large eyes and round pupils. Scales are keeled (ridged). A diagnostic dark spot is usually present beneath each eye and on the sides of the neck.
Size & Dimensions
Currently pictured is likely an adult. Typical size range is 23 to 33 cm (9 to 13 inches), with a maximum recorded length of approximately 49 cm (19 inches).
Habitat
Generalist species found in various habitats including wetlands, grasslands, and forests, but exceptionally common in suburban and urban environments. They favor microhabitats under debris, logs, rocks, and leaf litter.
Behavior & Temperament
Docile and secretive. Primarily crepuscular or nocturnal, especially in warm weather. Defensive behaviors include flattening the body to appear larger and releasing a mild musk from the cloaca, but they rarely attempt to bite.
Diet & Feeding
Specialized feeder primarily consuming soft-bodied invertebrates like slugs and earthworms. They use their specialized teeth and jaw structure to pull snails from their shells.
Reproduction
Viviparous (gives birth to live young). Mating occurs in spring, and females give birth to 3 to 40 young in late summer. Neonates are very small, often measuring only 7-10 cm.
Venom Profile
Venom Type

Look-alikes
Often confused with the Red-bellied Snake (Storeria occipitomaculata), which has a bright red/orange belly, or juvenile Garter Snakes (Thamnophis ssp.), which typically have more prominent longitudinal stripes.
Conservation Status
Least Concern (IUCN). Extremely resilient to human disturbance and common throughout its range.
Cultural Significance
A valuable 'backyard' species that provides natural pest control by eating garden slugs and snails. They are one of the most frequently encountered snakes by urban homeowners.
Notable Features
Remarkable for its ability to thrive in dense urban centers where other snake species have been extirpated, often persisting in tiny vacant lots or container gardens.
