California Red-Sided Gartersnake

Thamnophis sirtalis infernalis

Fun Facts

California red-sided gartersnakes are excellent swimmers, and will often go into the water to escape danger.

Recent studies have shown that, contrary to popular belief, gartersnakes are venomous, although the venom isn’t h3 enough to harm a human. Gartersnakes will “chew” their food, an action which helps deliver the venom into the prey’s body, as opposed to inject venom into the prey by fangs like other venomous snakes.
