Painted turtles can be found in rivers and lakes along the northern edge of the park.
The bullsnake (Pituophis catenifer sayi) is a large non-venomous colubrid snake, widespread in the part of the United States, northern Mexico, and southern Canada. It is a subspecies of the gopher snake (Pituophis catenifer). The epithet sayi is in honor of zoologist Thomas Say.
In Yellowstone, it is the park's largest reptile ranging from 50 to 72 inches long. It is found at lower elevations, drier, warmer climates, and open areas such as near Mammoth Hot Springs. The bullsnake lives in burrows and eats small rodents. It is often mistaken for a rattlesnake because of its appearance and its defensive behavior; when disturbed it will coil up, hiss loudly, and vibrate its tail against the ground, producing a rattling sound. [1]
The prairie rattlesnake (Crotalus viridis viridis) is a venomous pitviper species native to the western United States, southwestern Canada, and northern Mexico.
In Yellowstone, this is the only dangerously venomous snake in the park. It lives in the lower Yellowstone River areas of the park, including Reese Creek, Stephens Creek, and Rattlesnake Butte, where the habitat is drier and warmer than elsewhere in the park. Its behavior is usually defensive rather than aggressive. There have been only two rattlesnake bites reported during the history of the park. [2]
The rubber boa (Charina bottae) is a snake in the family Boidae and genus Charina. The Boidae consists of the nonvenomous snakes commonly called boas and consists of 43 species. The genus Charina consists of four species, three of which are found in North America, and one species found in Africa.
In Yellowstone this snake is infrequently encountered in due to its nocturnal and burrowing habits. It eats rodents and may spend a great deal of time partially buried under leaves and soil, and in rodent burrows. It is usually found in rocky areas near streams or rivers, with shrubs or trees nearby. The most recent occurrences in the park have been in the Bechler region and Gibbon Meadows. [3]
The sagebrush lizard (Sceloporus graciosus graciosus) is a common lizard found in mid to high latitudes in the Western United States of America. It belongs to the genus Sceloporus (spiny lizards) in the Phrynosomatidae family of reptiles. Named after the sagebrush plants near which it is commonly found, the sagebrush lizard has keeled and spiny scales running along its dorsal surface.
In Yellowstone, this is the only lizard found in the park. It is usually found below 6,000 feet elevation, but in Yellowstone it can live up to 8,300 feet. Populations living in thermally influenced areas are possibly isolated from others. It is most common along the lower portions of the Yellowstone River near Gardiner, Montana and upstream to the mouth of Bear Creek. It also occurs in Norris Geyser Basin, Shoshone and Heart Lake geyser basins, and other hydrothermal areas. [4]
The valley garter snake (Thamnophis sirtalis fitchi) is a subspecies of the common garter snake. It is a snake indigenous to North America. Most garter snakes have a pattern of yellow stripes on a brown background and their average length is about 1 metre (3.3 ft) to 1.5 metres (4.9 ft). The common garter snake is a diurnal snake. In summer, it is most active in the morning and late afternoon; in cooler seasons or climates, it restricts its activity to the warm afternoons.
In Yellowstone, it was once thought to be common, but is now in decline for no apparent reason. In Yellowstone, it is only observed in the Fall River drainage in the Bechler region. [5]
The wandering garter snake (Thamnophis elegans vagrans) is a subspecies of the western terrestrial garter snake, a species of colubrid snake residing only in Southwestern Canada, and Western United States. Seven subspecies are currently recognized. Most snakes have a yellow, light orange, or white dorsal stripe, accompanied by two stripes on its side of the same color. Some varieties have red or black spots between the dorsal stripe and the side stripes. This snake often inhabits coniferous forests, and is relatively aquatic.
In Yellowstone, this is the most common reptile in the park. It is usually found near water in all areas of the park. It eats small rodents, fish, frogs, tadpoles, salamanders, earthworms, slugs, snails, and leeches. [6]
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 Calabar python is a species of non-venomous snake in the family Boidae. The species is endemic to West and Central Africa. It is the only species in its genus.
Pituophis catenifer is a species of nonvenomous colubrid snake endemic to North America. Nine subspecies are currently recognized, including the nominotypical subspecies, Pituophis catenifer catenifer, described here. This snake is often mistaken for the prairie rattlesnake, but can be easily distinguished from a rattlesnake by the lack of black and white banding on its tail and by the shape of its head, which is narrower than a rattlesnake's.
The rubber boa is a species of snake in the family Boidae and is native to western North America. It is sometimes known as the coastal rubber boa or the northern rubber boa and is not to be confused with the southern rubber boa.
The western terrestrial garter snake is a western North American species of colubrid snake. At least five subspecies are recognized.
Pituophis catenifer deserticola, commonly known by its standardized English name since the 1950s, the Great Basin gophersnake, is a subspecies of nonvenomous colubrid snake ranging in parts of western United States and adjacent southwestern Canada.
The bullsnake is a large, nonvenomous, colubrid snake. It is a subspecies of the gopher snake. The bullsnake is one of the largest/longest snakes of North America and the United States, reaching lengths up to 8 ft.
Wyoming is home to 12 amphibian species and 22 species of reptiles.
There are 14 species of amphibians and 5 species of reptiles known to occur in Mount Rainier National Park.
