Thamnophis elegans terrestris
Thamnophis elegans terrestrisAlso known as Coast Garter Snake, California Coast Garter Snake, Coastal Garter Snake
Coast garter snakes range along the central California shoreline, easily recognized by bright yellow or orange dorsal stripes paired with rich red spots along their sides. They forage during the day in moist environments, hunting everything from banana slugs and earthworms to amphibians and small fish. Females give birth to live young late in the summer, producing litters of up to two dozen active snakelets.

- Why interaction risk is low
- May bite defensively or emit a pungent musk if handled; observe quietly from a short distance.
Responsible observation
- Observe Quietly: Approach slowly along trail edges, as ground vibrations easily startle them into thick brush.
- Avoid Handling: Picked-up snakes frequently release a foul-smelling musk and may deliver a defensive bite.
- Check Damp Spots: Look around moist stream margins, logs, and coastal meadows on sunny mornings.
