Carphophis vermis (common name western worm snake) [5] is a species of small, nonvenomous colubrid snake native to the United States.
The specific name, vermis, is Latin for "worm". [6]
The western worm snake has a dark, black or purplish dorsal coloration, with a lighter, pink or reddish underside. [7]
Adults are usually from 19–28 cm (7.5–11 in) in total length (including tail); however, the maximum recorded total length is 37.5 cm (14.8 in). [8]
The western worm snake is found in the United States in southern Iowa, southeastern Nebraska, eastern Kansas, western Illinois, Missouri, Louisiana, eastern Oklahoma, and northeastern Texas with isolated records from southwestern Wisconsin, southeastern Arkansas and middle Tennessee. [4]
C. vermis is fossorial, and spends the vast majority of time buried in loose, rocky soil, or under damp forest leaf litter. It is abundant within its range, but rarely seen due to its secretive nature. [9]
Little is known about the mating habits of the western worm snake, but breeding likely occurs in the early spring. Eggs are laid in the early summer. Clutch size is normally 1-8 eggs, and hatching takes place in August or September. Hatchlings range in size from 3 to 4 inches (7.6 to 10.2 cm) in total length.
The western worm snake's diet consists almost entirely of earthworms, [9] but it will also consume soft-bodied insects.
If harassed, C. vermis will often release foul smelling musk from its cloaca. If handled, it may press its tail tip into the captor's hand as a defense mechanism.
Rena humilis, known commonly as the western blind snake, the western slender blind snake, or the western threadsnake, is a species of snake in the family Leptotyphlopidae.

Eleven subspecies, including the nominotypical subspecies, are recognized, which as a group are commonly referred to as the eastern racers. The species is monotypic in the genus Coluber.
Nerodia rhombifer, commonly known as the diamondback water snake, is a species of nonvenomous natricine colubrid endemic to the central United States and northern Mexico. There are three recognized subspecies of N. rhombifer, including the nominotypical subspecies.
The smooth earth snake is a species of nonvenomous natricine colubrid snake native to the eastern half of the United States.

The eastern worm snake is a subspecies of the worm snake, Carphophis amoenus, a nonvenomous colubrid endemic to the Eastern Woodlands region of North America. The species' range extends from southwest Massachusetts, south to southern Alabama, west to Louisiana and north to Illinois. This species is common in the ecotone between woodlands and wetlands. It may also be found in grasslands adjacent to woodlands. Though this snake can be abundant in parts of its range, it is rarely seen because of its fossorial lifestyle. When not underground, C. a. amoenus resides mostly under rocks, logs and leaf litter, or burrowed within rotting woody debris. This snake is perfectly safe to pick up, as it cannot bite, but may produce a foul-smelling excretion.
Thamnophis proximus, commonly known as the western ribbon snake, is a species of garter snake in the subfamily Natricinae of the family Colubridae. The species is endemic to the western United States, Mexico, and Central America. The species has six recognized subspecies.
The midwestern worm snake, Carphophis amoenus helenae, a subspecies of C. amoenus, is a nonvenomous snake in the family Colubridae. The subspecies is endemic to the Midwest and Southern United States.
Carphophis amoenus, commonly known as the worm snake, is a species of nonvenomous colubrid snake endemic to the eastern United States. C. amoenus can be found east of the Mississippi, from southwest Massachusetts south to southern Alabama west to Louisiana and then north to Illinois. This species of snake protects a large range, and normally prefers a moist habitat in the rocky woodlands, under rotten wood of logs and stumps. Though this snake is quite abundant over its range, it is rarely seen because of its dormant lifestyle and where it usually resides. This snake is most common on the edges or in the ecotonal areas of open to thick woodlands, and the borders of wetlands. It may also be found in the grasslands next to woodlands. The best chance to spot it is after heavy rains, when its small size and distinct color make it easy to spot. This species prefers moist soil inhabited by earthworms, which are its main prey, so the soil needs to be sufficiently moist. The snake's skin naturally evaporates water; so the soil needs to be moist enough to offset this. C. amoenus is mostly found under rocks and in sufficient leaf litter during the extreme daytime heat. Peak activity falls between 15:00 to 18:00.
