Carphophis (common name worm snakes) is a genus of small colubrid snakes endemic to the United States. The genus consists of two species, one of which has two subspecies. [2]
Worm snakes are small snakes, 35 cm (14 in) or less in total length (including tail). The males are shorter than the females. [2] Both sexes are usually a dark brown in color on the upperside, with a lighter-colored, pink or orange underside. Both species are cylindrical and unpatterned, with a pointed head and small black eyes. [2] They are easily mistaken for other similar species, such as the earth snakes (genus Virginia ) and the brown snakes (genus Storeria ). Worm snakes have narrow heads, sharp tail tips, and are not venomous.
Worm snakes are fossorial snakes, and spend the vast majority of their time buried in loose, rocky soil, or under forest leaf litter. They predominantly reside in cool, moist soils next to streams, hilly woodlands, pine forest stands, partially grassy woodsides, and farmland bordering woodlands. [3] These species have fairly small home ranges (253 square meters) and the daily activity is from 3-6pm. [4] It was seen that most periods of activity were for less than 12 hours, while the periods of inactivity can range from a few minutes to over two weeks. [5] Worm snakes are abundant within their ranges, but rarely seen due to their secretive nature. Studies have shown that if these species are displaced, there is no homing ability that is exhibited. [6]
Little is known about the mating habits of worm snakes, but breeding likely occurs in early spring. The eggs are laid in early summer. Clutch size is normally two to five eggs, and hatching takes place in August or September. Hatchlings range in size from 7 to 12 cm (about 3-5 inches). The young can mature within three years. [7]
Worm snakes eat almost entirely earthworms, and other annelids. Studies have shown that they have consumed soft-bodied insects and other invertebrate prey. [8]
Worm snakes are a common food source for ophiophagous snake species, such as the coral snakes, Micrurus fulvius and Micrurus tener , in areas in which they are sympatric. They can also be threatened by opossums, shrews, and moles, as well as birds. [9]
Nota bene : A binomial authority or trinomial authority in parentheses indicates that the species or subspecies was originally described in a genus other than Carphophis.
Kingsnakes are colubrid New World members of the genus Lampropeltis, which includes 26 species. Among these, about 45 subspecies are recognized. They are nonvenomous and ophiophagous in diet.
The scarlet kingsnake or scarlet milk snake is a species of kingsnake found in the southeastern and eastern portions of the United States. Like all kingsnakes, they are nonvenomous. They are found in pine flatwoods, hydric hammocks, pine savannas, mesic pine-oak forests, prairies, cultivated fields, and a variety of suburban habitats; not unusually, people find scarlet kingsnakes in their swimming pools, especially during the spring. Until recently, and for much of the 20th century, scarlet kingsnakes were considered a subspecies of the milk snake; however, Pyron and Bubrink demonstrated the phylogenetic distinction of this species and its closer relationship to the mountain kingsnakes of the southwestern United States. These largely fossorial snakes are the smallest of all the species within the genus Lampropeltis, usually ranging from 40 to 50 cm at maturity. The maximum recorded length is in Jonesboro, AR 76.2 cm (30.0 in). Hatchlings range in size from 8 to 18 cm .
Coral snakes are a large group of elapid snakes that can be divided into two distinct groups, the Old World coral snakes and New World coral snakes. There are 27 species of Old World coral snakes, in three genera, and 83 recognized species of New World coral snakes, in two genera. Genetic studies have found that the most basal lineages have origins in Asia, suggesting that the group originated in the Old World. While new world species of both genera are venomous, their bites are seldom lethal; only two confirmed fatalities have been documented in the past 100 years from the genus Micrurus. Meanwhile, snakes of the genus Micruroides have never caused a medically significant bite.
Robert Kennicott was an American naturalist and herpetologist. Chronic illness kept Kennicott out of school as a child. Instead, Kennicott spent most of his time outdoors, collecting plants and animals. His father schooled him at home and convinced naturalist Jared Potter Kirtland to take him as an understudy. Soon, Kennicott was providing specimens for the Smithsonian Institution via assistant secretary Spencer Fullerton Baird.
Nerodia is a genus of nonvenomous colubrid snakes commonly referred to as water snakes due to their aquatic behavior. The genus includes nine species, all native to North America. Five of the species have recognized subspecies.
Carphophis vermis is a species of small, nonvenomous colubrid snake native to the United States.
Micrurus tener, commonly known as the Texas coral snake, is a species of venomous snake in the family Elapidae. The species is native to the southern United States and adjacent northeastern and central Mexico. Six subspecies are recognized as being valid, including the nominotypical subspecies, Micrurus tener tener The species Micrurus tener was once considered to be a subspecies of the eastern coral snake.
Virginia striatula, commonly called the rough earth snake, is a species of nonvenomous natricine colubrid snake native to the Southeastern United States.
Micrurus fulvius, commonly known as the eastern coral snake, common coral snake, American cobra, and more, is a species of highly venomous coral snake in the family Elapidae.The Elapidae family also contains the cobras and sea snakes. The species is endemic to the southeastern United States. It should not be confused with the scarlet snake or scarlet kingsnake, which are harmless mimics. No subspecies are currently recognized.
Kirtland's snake is a threatened or endangered North American species of nonvenomous snake of the subfamily Natricinae, of the family Colubridae. It is the only species in the genus Clonophis.
Lampropeltis getula, commonly known as the eastern kingsnake, common kingsnake, or chain kingsnake, is a harmless colubrid species endemic to the United States. It has long been a favorite among collectors. Four subspecies are currently recognized, including the nominate subspecies described here. All of these taxa had originally been described as distinct species and recognized as such for up to 101 years.
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.
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.
Micruroides is a genus of venomous coral snake in the family Elapidae. The genus is monotypic, containing only the species Micruroides euryxanthus.
Lampropeltis triangulum triangulum, commonly known as the eastern milk snake or eastern milksnake, is a subspecies of the milk snake. The nonvenomous, colubrid snake is indigenous to eastern and central North America.
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.
