Description: Adults are 18" - 49". They may have paired blotches at the back of the head running down back. There is a yellowish or cream middorsal stripe that runs down the back. Dorsal scales are keeled. In parts of its range it has obscure black body spots.
Venom: Garters were long thought to be nonvenomous, but recent discoveries have revealed that they do in fact produce a mild neurotoxic venom. Garter snakes cannot kill humans with the small amounts of venom they produce, which is comparatively mild, and they also lack an effective means of delivering it. They do have enlarged teeth in the back of their mouth, but their gums are significantly larger. The Duvernoy's gland of garters are posterior (to the rear) of the snake's eyes. The mild venom is spread into wounds through a chewing action. - Wikipedia
