Found in Missouri, Texas, western states, and parts of Kansas, the collared lizard is the state reptile of the... less ↑

The Texas horned lizard (Phrynosoma cornutum) is one of about 14 North American species of spikey-bodied reptiles called horned lizards. P. cornutum ranges from Colorado and Kansas to northern Mexico (in the Sonoran desert), and from southeastern Arizona to Texas. There are also isolated, introduced populations in the Carolinas, Georgia, and northern Florida. Texas horned lizards may be native to Louisiana and Arkansas. 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 snake is commonly found living near water sources such as streams and ponds, but can also be found in urban... less ↑

The ring-necked snake or ringneck snake, Diadophis punctatus, is a species of colubrid snake found throughout much of the United States, central Mexico, and southeastern Canada. Ring-necked snakes are secretive, nocturnal snakes, so are rarely seen during the day time. They are slightly venomous, but their nonaggressive nature and small, rear-facing fangs pose little threat to humans who wish to handle them. They are best known for their unique defense posture of curling up their tails,... 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 ↑

Arizona elegans is a species of medium-sized colubrid snake commonly referred to as the glossy snake or the faded snake, which is endemic to the southwestern United States and Mexico. The genus Arizona has only one officially recognized species, A. elegans, with several subspecies. Some have recommended that A. elegans occidentalis be granted full species status. 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 ↑

Lampropeltis triangulum, commonly known as a milk snake or milksnake, (French: Couleuvre tachetée; Spanish: Culebra-real coralillo) is a species of king snake. There are 24 subspecies of milk snakes.

The epithet emoryi is in honor of Brigadier General... less ↑

The Red Cornsnake (Pantherophis guttatus), corn snake, or red rat snake, is a North American species of rat snake that subdues its small prey by constriction. The name "corn snake" is a holdover from the days when southern farmers stored harvested ears of corn in a wood frame or log building called a crib. Rats and mice came to the corn crib to feed on the corn, and corn snakes came to feed on the rodents.... 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 ↑

Virginia opossum tracks generally show five finger-like toes in both the fore and hind prints. The hind tracks are unusual and distinctive due to the opossum's opposable thumb, which generally prints at an angle of 90° or greater to the other fingers (sometimes near 180°). Individual adult tracks generally measure 1.9 in long by 2.0 in wide (4.8 × 5.1 cm) for the fore prints and 2.5 in long by 2.3 in wide (6.4 × 5.7 cm) for the... less ↑

The silky pocket mouse lives in low valley bottoms with soft soils, where they can live among weeds and shrubs and... 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. The muskrat is found in wetlands over a wide range of climates and habitats. It has important effects on the ecology of wetlands and is a resource of food and fur for humans. It is an introduced species in some of its present range. less ↑

The western harvest mouse (Reithrodontomys megalotis) is a small neotomine mouse native to southwest British Columbia, most of the western United States extending continuously to west Texas, northeast Arkansas, northwest Indiana, southwest Wisconsin, the interior of Mexico to Oaxaca. Many authorities consider the endangered Salt Marsh Harvest Mouse to be a subspecies, but the two are now usually treated separately. less ↑

The hispid cotton rat (Sigmodon hispidus) is a rodent species long thought to occur in parts of South America, Central America, and southern North America. However, recent taxonomic revisions, based on mitochondrial DNA sequence data, have split this widely distributed species into three separate species (S. hispidus, S. toltecus, and S. hirsutus). Carroll et al. (2004) indicate that the southern edge of the S. hispidus distribution is likely near the Rio Grande where it meets 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 white-tailed deer (Odocoileus virginianus), also known as the Virginia deer or simply as the whitetail, is a medium-sized deer native to the United States, Canada, Mexico, Central America, and South America as far south as Peru.

The stoat (Mustela erminea), also known as the short-tailed weasel, is a species of Mustelidae native to Eurasia and North America, distinguished from the least weasel by its larger size and longer tail with a prominent black tip. The name ermine is often, but not always, used for the animal in its pure white winter coat, or the fur thereof. In the late 19th century, stoats were introduced into New Zealand to control rabbits. The stoats... less ↑

The black-footed ferret (Mustela nigripes), also known as the American polecat or prairie dog hunter, is a species of mustelid native to central North America. It is listed as endangered by the IUCN, because of its very small and restricted populations. First discovered by Audubon and Bachman in 1851, the species declined throughout the 20th century, primarily as a result of decreases in prairie dog populations and sylvatic plague. It was declared extinct in 1979 until... less ↑

The American hog-nosed skunk (Conepatus leuconotus) is a species of hog-nosed skunk from Central and North America, and is one of the largest skunks in the world, growing to lengths of up to 2.7 feet (82.5 cm). Recent work has concluded the western hog-nosed skunk (formerly Conepatus mesoleucus) is the same species, and Conepatus leuconotus is the correct name of the merged populations. less ↑

The bobcat (Lynx rufus) is a North American mammal of the cat family Felidae, appearing during the Irvingtonian stage of around 1.8 million years ago (AEO). With 12 recognized subspecies, it ranges from southern Canada to northern Mexico, including most of the continental United States.
