The Woodhouse's Toad, (Bufo woodhousii) is a medium-sized (4 inches or 10 centimetres) true toad, which is native to the United States and Mexico. There are two recognized subspecies. The epithet woodhousii is in honor of the American physician and naturalist Samuel Washington Woodhouse.B. woodhousii tends to hybridize with Bufo americanus in their overlapping ranges. less ↑

The American bullfrog (Lithobates catesbeianus), often simply known as the bullfrog in Canada and the United States, is an aquatic frog, a member of the family Ranidae, or “true frogs”. This species has traditionally been classified as Rana catesbeiana, however the classification has been changed to Lithobates due to paraphyly in Ranidae. This frog has an olive green back and sides blotched with brownish markings and a whitish belly spotted with yellow or grey. The upper... less ↑

The short-horned lizard (Phrynosoma hernandesi) is a small lizard that occurs in North America. Like other horned lizards, it is often wrongly called the "Horned Toad" or "Horny Toad," but it is not a toad at all. It is a reptile, not an amphibian. It is one of seven native species of lizards in Canada. The species name, hernandesi, honors Francisco Hernández Médico who wrote an early account in 1651 of a Horned Lizard. less ↑

The Plains garter snake (Thamnophis radix) 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... less ↑

Western Hognose snakes are relatively small, stout-bodied snakes found throughout the Great Plains states of the U.S. from Canada to Mexico. Their color and pattern is highly variable from subspecies to subspecies, although most specimens appear much like the infamous rattlesnake to the untrained eye. This optical bluff, used in conjunction with a wide array of other clever defense tactics, makes these snakes quite unique among North American serpents. less ↑

Pituophis catenifer is a species of nonvenomous colubrid snake endemic to North America. Six subspecies are currently recognized, including the nominotypical subspecies, Pituophis catenifer catenifer, described here. This snake is often mistaken for a diamondback 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. less ↑

The common snapping turtle (Chelydra serpentina) is a large freshwater turtle of the family Chelydridae. Its natural range extends from southeastern Canada, southwest to the edge of the Rocky Mountains, as far east as Nova Scotia and Florida. This species and the larger alligator snapping turtle are the only two species in this family found in North America (though the common snapping turtle, as its name implies, is much more widespread). less ↑

The painted turtle (Chrysemys picta) is the most widespread native turtle of North America. It lives in slow-moving fresh waters, from southern Canada to Louisiana and northern Mexico, and from the Atlantic to the Pacific. The turtle is the only species of the genus Chrysemys, which is part of the pond turtle family Emydidae. Fossils show that the painted turtle existed 15 million years ago. Four regionally based subspecies (the eastern, midland, southern, and western) evolved during... less ↑

The Virginia opossum (Didelphis virginiana), commonly known as the North American opossum, is the only marsupial found in North America north of Mexico. In the United States it is typically referred to simply as a possum. A solitary and nocturnal animal about the size of a domestic cat, and thus the largest opossum, it is a successful opportunist. It is familiar to many North Americans as it is often seen near towns, rummaging through garbage cans,... less ↑

The black-tailed jackrabbit (Lepus californicus), also known as the American desert hare, is a common hare of the western United States and Mexico, where it is found at elevations from sea level to up to 10,000 feet (3,000 m).

The black-tailed jackrabbits... less ↑

The black-tailed prairie dog (Cynomys ludovicianus), is a rodent of the family Sciuridae found in the Great Plains of North America from about the USA-Canada border to the USA-Mexico border. Unlike some other prairie dogs, these animals do not truly hibernate. The black-tailed prairie dog can be seen above ground in midwinter. A black-tailed prairie dog town in Texas was reported to cover 64,000 km2 (25,000 sq mi) and included 400,000,000 individuals. Prior to habitat destruction, this species may... less ↑

The North American beaver (Castor canadensis) is one of two extant beaver species. It is native to North America and introduced to Patagonia in South America and some European countries (e.g. Norway). In the United States and Canada, the species is often referred to simply as "beaver", though this causes some confusion because another distantly related rodent, Aplodontia rufa, is often called the "mountain beaver". Other vernacular names, including American beaver and Canadian beaver, distinguish this... less ↑

The plains pocket gopher (Geomys bursarius) is one of thirty-five species of pocket gopher, so named in reference to their externally located, fur-lined cheek pouches. They are burrowing animals, found in grasslands and agricultural land across the Great Plains of North America, from Manitoba to Texas. Pocket gophers are the most highly fossorial rodents found in North America. less ↑

The North American porcupine (Erethizon dorsatum), also known as the Canadian porcupine or common porcupine, is a large rodent in the New World porcupine family. The beaver is the only larger rodent in North America. The porcupine is a caviomorph rodent whose ancestors rafted across the Atlantic from Africa to Brazil over 30 million years ago, and then migrated to North America during the Great American Interchange after the Isthmus of Panama rose 3 million years... less ↑

The muskrat (Ondatra zibethicus), the only species in genus Ondatra and tribe Ondatrini, is a medium-sized semiaquatic rodent native to North America, and introduced in parts of Europe, Asia, and South America.

Although occurring at lower elevations during the Pleistocene, it generally is limited now to highlands supporting open coniferous forests or woodlands. In a few places, it occurs in lower country where lava or boulder fields occur; presumably the... less ↑

The meadow jumping mouse (Zapus hudsonius) is the most widely distributed mouse in the subfamily Zapodinae. Its range extends from the Atlantic coast in the east to the Great Plains west, and from the arctic tree lines in Canada and Alaska to the north, and Georgia, Alabama, Arizona, and New Mexico to the south. In mid-2014, the New Mexico subspecies of the meadow jumping mouse, Zapus hudsonius luteus, was listed as an endangered species under the... less ↑

The mule deer (Odocoileus hemionus) is a deer indigenous to western North America; it is named for its ears, which are large like those of the mule. There are believed to be several subspecies, including the black-tailed deer. However, some genetic studies have indicated that mule deer may have developed relatively recently through the interbreeding of white-tailed and black-tailed deer, which may have evolved from white-tailed deer thousands of years ago. Unlike the related white-tailed deer... less ↑

The elk or wapiti (Cervus canadensis) is one of the largest species of the Cervidae or deer family in the world, and one of the largest land mammals in North America and eastern Asia. It was long believed to be a subspecies of the European red deer (Cervus elaphus), but evidence from a 2004 study of the mitochondrial DNA indicates that the two are distinct species. less ↑
