Maritime Garter Snake

Thamnophis sirtalis pallidulus

Maritime garter snakes are subtle, grayish or brownish reptiles known for having faint or incomplete dorsal stripes compared to other garter snake subspecies. They inhabit damp forests, meadows, stream margins, and coastal zones across eastern Canada and northern New England. Active during the day, these adaptable hunters rely on cryptic coloration as they stalk earthworms, amphibians, and small fish along freshwater edges.

Why interaction risk is low
Harmless to humans, though it may musk or nip if caught; observe quietly from a short distance.
Responsible observation
  • Observation: Look along sunny trail edges, logs, and stone piles near wetlands during cool mornings.
  • Handling: Avoid handling wild individuals, as they readily discharge a foul musk when threatened.
  • Road Awareness: Watch for slow-moving snakes warming themselves on paved surfaces on autumn afternoons.
