The Mexican wandering garter snake (Thamnophis errans) is a species of snake of the family Colubridae. It is endemic to Mexico.
This snake was first described as species new to science in 1942. [2] Subsequently, some authors have noted similarities between northern populations of the Mexican wandering garter snake and the southern subspecies of the western terrestrial garter snake (Thamnophis elegans vagrans), leading them to reclassify the former as another subspecies of the western terrestrial garter snake under the name Thamnophis elegans errans. [2] However, a 280 km gap of uninhabitable low desert separates the ranges of the two populations. [2] Additionally, even the closest populations of Mexican wandering and western terrestrial garter snakes are still morphologically separated by the number and arrangement of scales, as well as the color of the tongue. [2] Presently, Thamnophis errans is considered a valid taxon. [3]
The Mexican wandering garter snake is endemic to Mexico, where it has been found in the states of Chihuahua, Durango, Jalisco, Nayarit, and Zacatecas. [4] [2] It has an extensive linear range in the pine-oak forests of the Sierra Madre Occidental. [2] When conditions allow, this species is widely dispersed within its range. It can be found near streams or ponds, but may also be found around rock piles or logs some distance from permanent water. [5]
Garter snake is the common name for small to medium-sized snakes belonging to the genus Thamnophis in the family Colubridae. Native to North and Central America, species in the genus Thamnophis can be found in all of the lower 48 United States, and nearly all of the Canadian provinces south of the Northwest Territories and Nunavut—with the exception of Newfoundland and Labrador. They are found from the subarctic plains of west-central Canada east through Ontario and Quebec; from the Maritime Provinces and south to Florida, across the southern and central U.S. into the arid regions of the southwest and Mexico, Guatemala and south to the neotropics and Costa Rica.
The common garter snake is a species of snake in the subfamily Natricinae of the family Colubridae. The species is indigenous to North America and found widely across the continent. There are several recognized subspecies. Most common garter snakes have a pattern of yellow stripes on a black, brown or green background, and their average total length is about 55 cm (22 in), with a maximum total length of about 137 cm (54 in). The average body mass is 150 g (5.3 oz). The common garter snake is the state reptile of Massachusetts.

The plains garter snake is a species of garter snake native to most of the central United States as far north as Canada and as far south as Texas. It has a distinctive orange or yellow stripe from its head to tail, and the rest of its body is mainly a gray-green color. The snake is commonly found living near water sources such as streams and ponds, but can also be found in urban areas and vacant lots. Although the IUCN lists the species as "Least Concern", some states have given it their own special status. This species is mildly venomous, although the venom is not toxic to humans.
