common garter snake

Also known as: Thamnophis sirtalis

Quick Summary

The common garter snake (Thamnophis sirtalis) is a nonvenomous snake native to North America, known for its striped pattern. It is one of the most widespread reptiles in North America and is generally harmless, though it may strike defensively and secrete a foul odor when handled.1

Garter snakes are small to moderate in size, typically under 100 cm (39 inches) long. They primarily feed on insects, earthworms, and amphibians. Unlike many snakes, they do not lay eggs; they give birth to live young in late summer. While most garter snakes are considered of least concern by conservation organizations, some species are threatened or endangered. It's important to note that while some snakes are venomous, garter snakes are not.12
