 | | Like all Garter Snakes, these snakes have lateral stripes or rows of spots (usually white, yellow, can be greenish, bluish, orange, or red), against a darker background (fl, dark green, greenish-brown, olive). |
 | | Sirtalis can be distinguished from other Thamnophis species by the location of the lateral strip. |
 | | One subspecies, the San Francisco garter snake, Thamnophis sirtalis tetrataenia, is considered endangered, and placed on the US and California Endangered Species list in 1967. |
