Western Blackneck Garter Snake

Other Names: Garden Snake, Gardener Snake, Grass Snake
Description: The top of the head is uniform gray with a light yellow to orange middorsal stripe separates 2 large blotches at the back of the neck. Olive gray to olive brown above, with 2 alternating rows of black or brown spots. Belly light greenish white or bluish white. Scales are keeled. Adults are 16"-46" in length.
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
