Description
The Exiled Garter Snake is both the smallest garter snake known (the largest specimen found was only 18 inches long) and the rarest (10 collected specimens from just three localities in northeastern Mexico). It has been found in montane meadows at high elevations.
Like North American rat snakes, the Exiled Garter Snake exhibits ontogenetic change: juveniles start out spotted; in adults the spotting becomes obscured.
