#213 Common Garter Snake (Thamnophis sirtalis)

27 September

A species of natricine snake, which is indigenous to North America and found widely across the continent. Most common garter snakes have a pattern of yellow stripes on a black, brown or green background, and their average total length (including tail) is about 55 cm (22 in), with a maximum total length of about 137 cm (54 in).

The saliva of a common garter snake may be toxic to amphibians and other small animals. Garter snakes have a mild venom in their saliva.[10] For humans, a bite is not dangerous, though it may cause slight itching, burning, and/or swelling. Most common garter snakes also secrete a foul-smelling fluid from postanal glands when handled or harmed.

Common garter snakes are resistant to naturally found poisons such as that of the American toad and rough-skinned newt, the latter of which can kill a human if ingested. They have the ability to absorb the toxin from the newts into their bodies, making them poisonous, which can deter potential predators.
