Description

The mud snake usually grows to a total length (including tail) of 40 to 54 inches (1-1.4 m), [4] with the record total length being slightly over 80 inches (2 m). [5]

This species is sexually dimorphic in size. Female adults are larger than males in total length. [6]

The upperside of the mud snake is glossy black. The underside is red and black, and the red extends up the sides to form bars of reddish-pink. Although, some have a completely black body with slightly lighter black spots instead of the common reddish colors.

The heavy body is cylindrical in cross section, and the short tail has a terminal spine.

The head scalation is distinctive in that there is only one internasal scale, no preocular scale, and one anterior temporal scale. The dorsal scales are smooth, and are arranged in 19 rows at midbody. There are 168–208 ventral scales and 31–55 subcaudal scales. The anal plate is divided. [7]

Farancia abacura is the only species that belongs to the Farancia genus, with two different subspecies within itself. [8]

Habitat

F. abacura inhabits the edges of streams and cypress swamps, among dense vegetation or under ground debris, using wet conditions to burrow itself into the mud. It is almost fully aquatic and rarely leaves the water, except to lay eggs, hibernate, or during drought to escape drying wetlands. [9] [10] After heavy rain fall, its home range may increase to take advantage of new food sources. [11] It occupies aquatic habitats with freshwater or brackish waters. [12] For hibernation, they commonly use cavities in soil or old tree stumps.

Behavior

The mud snake is mostly aquatic and nocturnal. It preys mostly on giant aquatic salamanders in the genera Siren and Amphiuma , but it also eats other amphibians. [13] They are known to use their sharply pointed tails to prod prey items, leading to the nickname "stinging snake", although their tail is not a stinger and cannot sting. Enlarged teeth occur at the rear of the upper jaw, which presumably help to hold slippery prey. Upon being disturbed, mud snakes will sometimes tuck their head beneath their coils and expose the red underside on the tail as a warning display. [14]

Reproduction

Breeding of F. abacura takes place in the spring, mostly in the months of April and May. During copulation, the female will wind itself around the male. They can stay in this position for over a day. [15] Eight weeks after mating, the female lays 4 to 111 [16] eggs in a nest dug out of moist soil, sometimes in alligator nests. [17] The nests of this species can commonly be found in the ground under debris, but it is not limited to those areas. These nests are cavities in sandy soil with the eggs laid within. Some eggs can even be embedded into the wall. [18] There is a positive correlation between body length and clutch size, with larger females having larger clutch sizes. [6] She will remain with her eggs until they hatch, [19] in the fall, usually September or October. Although unhatched eggs have not been found in the winter or spring, many juvenile mudsnakes are captured entering wetlands in the spring, most likely from clutches deposited and hatched in the preceding late summer or autumn. It is thought that mudsnake hatchlings either enter aquatic habitats in the autumn or delay entering them until the spring, but it is not known if they remain in a terrestrial nest or disperse into terrestrial habitats during this time. [20]

Geographic range

The mud snake is found in the southeastern United States, in the states of Alabama, Arkansas, Florida, Georgia, Illinois, Kentucky, Louisiana, Mississippi, Missouri, North Carolina, Oklahoma, South Carolina, Tennessee, Texas, and Virginia. [3]

Cultural significance

The mud snake is one of a few animals which may be the origin of the hoop snake myth. J.D. Willson writes:

Mud snakes are sometimes known as “hoop snakes” because of the myth that they will bite their own tail and roll after people. [3]

The hoop snake myth has also been attributed to the coachwhip snake.

Subspecies

There are two recognized subspecies of Farancia abacura, including the nominotypical subspecies:

<i>Amphiuma</i> Genus of amphibians

Amphiuma is a genus of aquatic salamanders from the United States, the only extant genus within the family Amphiumidae. They are colloquially known as amphiumas. They are also known to fishermen as "conger eels" or "Congo snakes", which are zoologically incorrect designations or misnomers, since amphiumas are actually salamanders, and not fish, nor reptiles and are not from Congo. Amphiuma exhibits one of the largest complements of DNA in the living world, around 25 times more than a human.

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.

<span class="mw-page-title-main">Eastern worm snake</span> Subspecies of snake

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.

<span class="mw-page-title-main">Eastern milk snake</span> Subspecies of snake

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.

<i>Carphophis amoenus</i> Species of snake

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.
