The southeastern crown snake (Tantilla coronata) is a common species of small colubrid snake endemic to the southeastern United States.
T. coronata is a small, slender snake, greyish-brown or solid light brown in color. It has a black, pointed head with a yellowish or cream band between the head and the neck. This is followed by a black collar 3 to 5 scales wide. The remainder of the back is reddish brown. The belly is light pink or solid white. [3] It has smooth dorsal scales in 15 rows and a divided anal plate. [1] Adults average 20–25 cm (8-10 inches) in total length. [4]
The snake is found in Alabama, northwestern Florida, Georgia, extreme southern Indiana, western Kentucky, eastern Louisiana, Mississippi, North Carolina, South Carolina, Tennessee, and south-central Virginia. [4] [5] The largest populations of the species is found in areas with sandy or loose soils and plentiful organic litter. The southeastern crown snake is commonly found in both damp and dry woodland habitats. [3]
The snake is active during the day during the warmer months of the year, and can be found underneath rocks, logs and organic litter. It hibernates during the coldest months of winter, but is active beneath organic litter on warm winter days. The snake travels overland at night, generally during the hours of early evening. It is considered a skilled burrower in sandy soil, and appears to "swim" in the sand when attempting to escape capture. [3]
The snake feeds on several kinds of small prey, including termites, worms, centipedes, earth-dwelling insect larvae, and spiders. [6] In the back of the snake's jaw are small, chiseled fangs that are used to inject venom into their prey. All crowned snakes are assumed to be non-venomous to humans. [3]
The southeastern crown snake is oviparous, generally laying 1-3 eggs per clutch. Mating occurs in the months from spring through fall. Females that mate in the fall store sperm until the following spring. Females lay their eggs typically in June and July. The eggs hatch in the fall. [3] [7]
Southeastern crown snakes are preyed upon by many carnivorous vertebrates that live in forested habitats. Their most common predator is the kingsnake and coral snake. The snake will attempt to burrow in the sand when threatened, or by crawling beneath organic litter and other debris. The snake does not bite when captured, but releases a foul-smelling musk from their scent glands. [3]
In most areas of its range, the southeastern crown snake is not considered to be a conservation risk. In Indiana, the snake is listed as an endangered species. [8] Damage or destruction to their forested habitats will have an adverse effect on the future population of the species. [3]
The smooth green snake is a species of North American nonvenomous snake in the family Colubridae. The species is also referred to as the grass snake. It is a slender, "small medium" snake that measures 36–51 cm (14–20 in) as an adult. It gets its common name from its smooth dorsal scales, as opposed to the rough green snake, which has keeled dorsal scales. The smooth green snake is found in marshes, meadows, open woods, and along stream edges, and is native to regions of Canada, the United States, and northern Mexico. A non-aggressive snake, it seldom bites and usually flees when threatened. It mates in late spring to summer, and females lay their eggs from June to September. The smooth green snake will often bob its head in order to mimic vegetation blowing in the wind.
Pantherophis vulpinus, commonly known as the foxsnake or the eastern fox snake, is a species of nonvenomous rat snake in the family Colubridae. The species is native to North America.
The long-nosed snake is a species of nonvenomous snake in the family Colubridae. The species is endemic to North America. It has two recognized subspecies. The other species in the genus were previously considered subspecies.
Cemophora coccinea, commonly known as the scarlet snake, is a species of nonvenomous snake in the family Colubridae. The species is native to the southeastern United States. There are two subspecies of C. coccinea that are recognized as being valid. The Texas scarlet snake was previously considered a subspecies.
The eastern race, or North American racer, is a species of nonvenomous snake in the family Colubridae. The species is endemic to North America and Central America. 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.
Carphophis vermis is a species of small, nonvenomous colubrid snake native to the United States.
The Texas lyre snake is a species of mildly venomous, rear-fanged snake in the family Colubridae. The species is endemic to the southwestern United States and adjacent northern Mexico.
Haldea striatula, commonly called the rough earth snake, is a species of nonvenomous natricine colubrid snake native to the Southeastern United States.
Rhineura floridana, known commonly as the Florida worm lizard, graveyard snake, or thunderworm, is a species of amphisbaenian in the family Rhineuridae. The species is the only extant member of the genus Rhineura, and is found primarily in Florida but has been recorded in Lanier County, Georgia. There are no subspecies that are recognized as being valid.
Farancia erytrogramma is a species of large, nonvenomous, highly aquatic, colubrid snake, which is endemic to coastal plains of the southeastern United States. Two subspecies are recognized as being valid, one of which has been declared extinct.
The striped whipsnake is a species of nonvenomous snake in the family Colubridae. It is closely related to the California whipsnake. The striped whipsnake is native to the western United States and adjacent northern Mexico.
Diadophis punctatus edwardsii, commonly known as the northern ringneck snake, is a subspecies of Diadophis punctatus, a snake in the family Colubridae. The subspecies is endemic to North America.
The eastern glass lizard is a species of legless lizard in the family Anguidae, endemic to the Southeastern United States. The streamlined, legless species is often confused with snakes. Glass lizards differ from snakes as they possess a moveable eyelid and an external ear opening, both of which are absent in snakes. Ventralis comes from the Latin "venter" meaning belly; this is in reference to the snake-like movement.
The Florida crowned snake is a species of colubrid snake found in Florida and Georgia. It is a small, slender, non-venomous snake that is rarely seen. The species is commonly found in north and central Florida, and is most often associated with sandy habitats.
The rim rock crowned snake, named after the Miami Rim Rock land arrangement, is a non-venomous endangered species of snake belonging to the family Colubridae. The rim rock crowned snake is endemic to the United States throughout southern Florida. The specific name, oolitica, refers to the oolitic limestone area of Florida in which the species is found. All species of snakes that belong to the genus Tantilla, are relatively small and usually do not exceed 20 cm (8 in). The species T. oolitica was added to the IUCN Red List in 2007 as a result of loss in habitat and restricted range.
The southern ribbon snake(Thamnophis saurita sackenii), also known commonly as the peninsula ribbon snake and the Florida ribbon snake, is a subspecies of garter snake in the family Colubridae. It is one of four subspecies of the ribbon snake.
The midland water snake, a subspecies of the northern water snake, is a nonvenomous natricine snake, which is endemic to North America.
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.
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.
