Viviparus georgianus was originally discovered and described (under the name Paludina georgiana) by Isaac Lea in 1834.[1]. Lee, L. E. J., J. Stassen, A. McDonald, C. Culshaw, A. D. Venosa and K. Lee. The lifespan of the female banded mysterysnails is typically between 28–48 months, while males live between 18–36 months (Jokinen et al., 1982; Lee et al., 2002). Unit Name. Breeding takes place in the spring (Pace and Szuch, 1985). Journal of Great Lakes Research 19(1):1-54. It is not quite so large, nor has it bands. [2][12][13] Females generally brood eggs for 9–10 months. Wade, J.Q., and C.E. The only time mystery snails feed on lives plants is when other sources aren’t available. 2002. Mystery Snail shells can be a solid color, have a color gradient, or have accents of … The Banded Mystery Snail (Viviparus georgianus) a non-native species to the Adirondacks was introduced in 1867 into the Hudson River. [2] It is usually absent from larger, faster flowing rivers;[3] however, it is able to survive conditions of high water velocity in the St. Lawrence River, and in the United States it may even be better adapted than the introduced species Bithynia tentaculata to such habitats. “With Bass Lake being a smaller lake, they just did well. The smaller ones might be faucet? Banded mystery snails are small animals with a coiled spiral shell. Gainesville, Florida. Jokinen, E.H., J. Guerette, and R.W. An exceptional stream population of the banded apple snail Viviparus georgianus in Michigan, USA. Shealy, Jr. 1972. Natively, mystery snails have been residing in ponds, rivers, and swamps around Bolivia, Paraguay, and Brazil. [2][10], Viviparus georgianus is known to be a facultative or even obligate filter-feeding detritivore. Snails in this family give birth to live young, complete with shells. Carlton, and C.L. This information is preliminary or provisional and is subject to revision. The natural history of an ovoviviparous snail Viviparus georgianus in a soft water eutrophic lake. Minneapolis, MN. Mystery Snail Appearance: Blue, Black, Gold and Purple. This species is found in freshwater low-flow lentic streams, lakes, and ponds. [21], In the Great Lakes Region: The first record of this introduced species in the Great Lakes basin is from the Hudson River drainage, connected to the Erie Canal and Mohawk River, in 1867. Need help identifying snails bagged during Starry Trek Other. This species is known to be the intermediate host for trematodes and has, as a result, been involved in spreading parasites to aquatic birds, resulting in large avian die-offs. Citation information: U.S. Geological Survey. 1962. I have 7 varieties of MYSTERY SNAILS for Freshwater Aquariums. The historic range of the banded mystery snail (BMS) is the southeastern U.S., primarily in the Mississippi River system up to Illinois. Lea) Description: The banded mystery snail is a member of the family Viviparidae. Banded mystery BANDED MYSTERY SNAIL (Viviparus cf. Secor. Duch T. M. (1976). The banded mysterysnail is native to North America, generally found in waterbodies of the southeastern and midwestern United States, from Central Florida up to northern Illinois, and throughout the eastern part of the Mississippi Drainage (Clench 1962). [7][19], A recent study found that Viviparus georgianus is in fact not one species, but a species complex in North America. Most growth generally occurs when waters become warmer in spring and summer, although reduced growth continues in winter (Browne, 1978; Jokinen et al., 1982). The species thrives in eutrophic lentic environments such as lakes, ponds and some low-flow streams. The shell of the Chinese mystery snail is large, spherical, and smooth. Vail, V.A. Strayer, D. 1987. It was determined that Viviparus limi is native to the Ochlockonee River and southwestern Georgia, while Viviparus goodrichi lives in the Florida panhandle and southwestern Georgia, and Viviparus georgianus defined sensu stricto is found in eastern and southern Florida as well as the Altamaha River in Georgia. A Mystery Snail is a freshwater aquarium snail often available in pet stores. Kortmann. Mystery Snails. New York State Museum Bulletin 482:vi -112. The banded mysterysnail and Chinese mystersnail are both distributed from the Niagara River, flowing into the Great Lakes. Leach, J.T. Pace, G.L., and E.J. The Nautilus 90(1):7-10. 1978. Clench, W.J. Viviparus georgianus, common name the banded mystery snail, is a species of large freshwater snail with gills and an operculum, an aquatic gastropod mollusk in the family Viviparidae, the river snails. The shell is up to 1.5 inches tall, and 1-1.5 inches wide. [6], The banded mystery snail often lives at high densities, sometimes up to around 864/m². 1986. Vincent, B. [18] Massachusetts, Indiana and Connecticut are probably some of the states marking the northern limit of this species’ native range. How did it get its name? It is rather more elevated, and the body whorl is smaller and rounder than the P. decisa (Say).

The Japanese variety of this species is black and usually a dark green, moss-like alga covers the shell. Because of this, it can be used as a bioindicator of sediment contamination by oil and fertilizer, because its growth, survival and histology are significantly affected by the ingestion of contaminated sediments. [17], The banded mystery snail is native to North America, generally found from the northeastern United States to Florida and the Gulf of Mexico[5] primarily in south central Florida, Georgia, Alabama and north, mainly in the Mississippi River system, to Illinois and northwestern Indiana. Szuch. Lee, L.E.J., J. Stassen, A. McDonald, C. Culshaw, A.D. Venosa, and K. Lee. [3], This species has invaded the northern part of the United States: Ohio, Michigan, Wisconsin, Virginia, Pennsylvania, New York, New Jersey, New England, as well as Quebec[18] and Ontario in Canada. Hydrobiologia 741(1):89-100. One-year old snails are 12–17 mm; at 2 years, 17–21 mm; and at 3 years, 21–30 mm (Lee et al. Piles of dead snail shells litter beaches making them unpleasant, much like zebra mussels. The operculum (“trapdoor”) is concentrically marked, with uniform color throughout, and no banding. Fuller. 1993. This species grazes on diatom clusters found on silt and mud substrates, but may require the ingestion of some grit to break down algae (Duch, 1976). 1982. Three distinct species were found to be in the Georgia-Florida drainages, each grouping by drainage: V. georgianus formed a western group in the Choctawhatchee and Apalachicola River Drainages, V. limi formed a central group in the Ochlockonee River Drainage and southwestern Georgia, while V. goodrichi was found to be present in the most eastern rivers extending into the Florida Peninsula. A guide to freshwater mollusks of the Laurentian Great Lakes with special emphasis on the genus Pisidium. It inhabits shallow waters, often amongst macrophytes, in spring to fall, before moving out to deeper areas to overwinter away from shore (Jokinen et al., 1982; Lee et al., 2002; Wade, 1985a), where it will burrow under the substrate for a period of inactivity (Pace and Szuch, 1985). Impacts: Both snails can form dense aggregations. Native to parts of the Mississippi River basin, Georgia, and Florida, this species was first reported in New York in 1854 in the Erie Canal. Ecology and zoogeography of the freshwater mollusks of the Hudson River Basin. Mystery Snail Tank Requirements. Professor Shepard. The data represented on this site vary in accuracy, scale, completeness, extent of coverage and origin. Since then, they have spread throughout southern Ontario. Snails as biomonitors of oil-spill and bioremediation strategies. The specific epithet georgianus is a reference to the southern State of Georgia, where the type locality is situated. Accessed [12/2/2020]. Freshwater Invertebrate Biology 1(4):2-17. The group is sexually dimorphic with females growing larger and faster than males, and reproductive females usually larger than 16 mm (Browne, 1978; Buckley, 1986). The Nonindigenous Occurrences section of the NAS species profiles has a new structure. [21] It is established in the Chesapeake Bay, Maryland. For queries involving invertebrates, contact Amy Benson. More individuals were released in 1867, resulting in an established population in the Hudson Drainage (Clench,1962; Strayer, 1987). Other records are from 1931 near Buffalo, Lake Erie and the Niagara River. [16] Female banded mystery snails live 28 – 48 and males live 18 – 36 months. [2][8], This snail is host to many parasites in its native habitat, including cercaria, metacercaria, ciliated protozoans, annelids, and chironomid larvae. The aperture at the base recedes more than is usual with this genus.

This species is also similar in shell shape and distribution with Viviparus intertextus and Viviparus subpureus (K. Cummings, Illinois Natural History Survey, pers. Chinese mystery snails are a source of food in Asia. Viviparus georgianus has been shown to significantly reduce survival of largemouth bass eggs in guarded nests both in the laboratory and in ponds, and may contribute to high incubation mortality seen in natural field settings (Eckblad and Shealy, 1972). It is the user's responsibility to use these data consistent with their intended purpose and within stated limitations. In Central Europe there are four species of the genus Cepaea (H eld 1838). A later genetic study found populations introduced in New York to group with the western complex, Viviparus georginaus (David et al., 2017). Aspects of the feeding habits of Viviparus georgianus. References to specimens that were not obtained through sighting reports and personal communications are found through the hyperlink in the Table 1 caption or through the individual specimens linked in the collections tables. Banded Mystery Snail (Viviparus georgianus. 1980. georgianus) In 1867, the Banded mystery snail made its way into the waterways of North America when it was released into the Hudson River. The most distinctive feature of the banded mystery snails (and where they get their name) are the red bands that run horizontally on the greenish-yellow colored shell. Rivest, B.R., and R. Vanderpool. The historic range of the banded mystery snail (BMS) is the southeastern U.S., primarily in the Mississippi River system up to Illinois. http://www.fwgna.org/species/viviparidae/v_georgianus.html. “(The banded mystery snails) are thick up there, but no one’s ever mentioned swimmer’s itch,” he said. The species is known as the Banded Mystery Snail and this was the first recorded sighting in the watershed to date. The inner shell is white to pale blue. This snail is found in lakes and slow-moving rivers with mud bottoms. They will grow to about 2 inches in diameter at most. Names and dates are hyperlinked to their relevant specimen records. Seasonal reproductive patterns in 3 viviparid gastropods. Rare and endangered species: freshwater gastropods of southern New England. The genetic identities of some populations remain undetermined, such as those of the Altamaha, Mississippi and St. Lawrence River drainages, and are therefore named as part of the V. georgianus species complex (Katoh and Foltz 1994). (1980) list this species as recorded from Lake Huron, but they do not give the date of establishment, or any references. 'Viviparus georgianus' ('Banded Mystery Snails)' in the southeastern United States appears to be a species complex. Jokinen, E. H., J. Guerette and R. W. Kortmann. With a variable diet, it will readily consume a herbivorous diet of algae and diatoms, but will also consume fish eggs (Duch, 1976; Eckblad and Shealy, 1972; Jokinen et al., 1982; Lee et al. Canadian Journal of Zoology 57(11):1271-2182. The bands may be hidden by algae or sediment. The outer shell is light to dark olive green to brownish. 1981.

Contact us if you are using data from this site for a publication to make sure the data are being used appropriately and for potential co-authorship if warranted. 1985. Why is the banded mystery snail a problem? Mackie, G.L., D.S. It is a … A study of the gastropods of Conesus Lake, Livingston County, New York. There was more reproduction,” he said. Wade, J.Q. The freshwater gastropods of North America. [2][12], This species grazes on diatom clusters found on silt and mud substrates, but it may also require the ingestion of some grit, in order to be able to break down algae. The snails grow to about the size of a golf ball, reproduce rapidly, and compete with imperiled native snails. Table 1. The Banded mystery snail is smaller than the Chinese mystery snail at 0.75 to 1.75 inches long and has 0-4 dark red spiral bands on its shell. Identification, occurrence and ecology of species. It is historically native to Florida and Georgia among other southeastern states. The Bulletin of the American Malacological Union, Inc. 50:52-53. Genetic subdivision and morphological variation in a freshwater snail species complex formerly referred to as Viviparus georgianus (Lea). David, A.A., Zhou, H., Lewis, A., Yhann, A., and S. Verra. It is dioecious (distinctly male or female) and ovoviviparous, with females laying eggs singly in albumen-filled capsules and brooding them for 9-10 months; this species is one of very few gastropods to give birth to live young (Browne, 1978; Jokinen et al., 1982; Lee et al. 1982. 1993. Studies of the gastropods of Conesus Lake, Livingston County, New York, USA II. Females can brood more than one clutch of young at a time and the number of young in one brood is positively related to the size of the female (Vail, 1977). Stewart, and W.K Reeves. We highly recommend reviewing metadata files prior to interpreting these data. 1976. 2002; Rivest and Vanderpool, 1986). It is often the dominant member of the macrofauna in its trophic level, both in number and function (Browne, 1978). Fecundity ranges from  4-81 young per female, but on average, is closer to 11 young per female (Jokinen, 1992; Vail, 1978). North Cass Unit Type. Banded mystery snails are non-native snails that are found in an increasing number of Wisconsin lakes. It is unclear whether the native range of this species includes the Tennessee River Drainage, but it is likely introduced to the drainage given the absence of the species from very extensive surveys from shell collectors in the area during mid-late 1800s (Clench 1962). Because it is a filter-feeding detritivore, Viviparus georgianus is a bioindicator of sediment contamination by oil and fertilizer, because growth, survival and histology are significantly affected by ingestion of contaminated sediments (Browne, 1978; Lee et al., 2002). [5][14] Females can brood more than one batch of young at a time, and the number of young in one brood is positively related to the size of the female. (Duch, 1976; Wade and Vasey, 1976; Vincent, 1979; Jokinen and Pondick, 1981; Pace and Szuch, 1985; Jokinen, 1992; Lee et al., 2002). (Smith, 2007). Shell ventricoso-conical, thin, dark horn coloured, smooth; sutures very much impressed; whorls about five, convex; aperture nearly round, white. This species is very similar to the European Viviparus viviparus. The list of references for all nonindigenous occurrences of Viviparus georgianus are found here. Where they might be: All three species are probably more widespread in Michigan than anyone realizes. The banded mystery snail (Viviparus georgianus) is one non-native invasive species that receives little attention. [22], This article incorporates public domain text from references.[1][21]. 2006. Lea's original text (the type description) reads as follows: Testa ventricoso-conoided, tenui, tenebroso-cornea, lævi; suturis valde iinpressis; anfractibus instar quinis, convexis; aperturâ subrotundatâ, albâ. The banded mystery snail (Viviparus georgianus, pronounced vi-vi-PAIR-us jor-jee-AN-us) is native to the southeastern US. A catalogue of the Viviparidae of North America with notes on the distribution of Viviparus georgianus. The table contains hyperlinks to collections tables of specimens based on the states, years, and drainages selected. The New Zealand mudsnail can be found in the Welland canal and the Great Lakes, including, Lake Ontario, Erie, Superior and Michigan. They grow up to one and a half inches tall and are light brown with red/brown horizontal bands that follow the spiral of the shell. [3], Other populations in the Altamaha, Mississippi and St. Lawrence River basins have not been studied yet with respect to their specific genetic make-up, and so they are simply named as being part of the Viviparus georgianus species complex. Although it takes much longer to grow, These guys have been raised in a calcium rich lower temp tank to … The Chinese mystery snail, black snail, or trapdoor snail (Cipangopaludina chinensis), is a large freshwater snail with gills and an operculum, an aquatic gastropod mollusk in the family Viviparidae. They have also been found in Lake Ontario, Lake Erie, and Kawartha Lakes, Trent River drainages and the Crowe and Moira River watershed. Bulletin of the American Malacological Union, Inc. 43:90. Mackie, G. L., D. S. White and T. W. Zdeba. This species is considered established in the waterbodies in which it introduced. The earliest introduction of this species to the Hudson River drainage was made by an amateur conchologist who purposefully released around 200 of these snails simultaneously into the river in the 1850s (Jokinen, 1992; Mills et al., 1993). comm., July 24, 2018). The maximum height is 45 mm (Jokinen, 1992). Horizontal brown bands … The “mystery” of these snails comes from their … [2][4][5][6][7][8][9], Viviparus georgianus breeds and lives in shallow waters, often amongst macrophytes, in spring to fall, then moves out to deeper areas in the fall in order to overwinter away from shore. One thing’s for sure- they love areas with decomposing or dead plants. Havel, J.E., L.A. Bruckerhoff, M.A. Eckblad, J.W., and M.H. 1976. 11/6. It was later reported from the Lake Michigan watershed by 1906 and Lake Erie by 1914. [4], Individuals are generally found in a range of habitats, including: regions with silt and mud substrate; communities dominated by diatoms and filamentous algae (not blue-green algae); shallow waters with sand or gravel substrate; soft and hard water; water with pH between 6.3 and 8.5; freshwater habitats only; river reaches more than meanders. Shells of the banded mystery snail can be as big as 1.75 inches long and have a right handed opening. Clench, W.J., and S.L.H. Biological Journal of the Linnean Society 53(1):73-90. It also has a dark brown patch behind the outer lip and on the umbilical region on the base of the shell. The shell opening is on the right when the shell is pointed up. White, and T.W. Where are mystery snails from and how did they get here? This snail is native to the southeastern United States. Duch, T.M. Accessed on 04/12/2018. This invasive species is suspected to harm native snails and lab studies found it may prey on fish larvae, reducing survival rates. The species was historically absent from most of the Atlantic coast drainages, and is known to have become established in the northeastern and midwestern United States as far back as the early 1900’s due to intentional releases, many from the aquarium trade (Clench, 1962; Mills et al., 1993; Dillon et al., 2006). It was brought to California in 1892 as a food source, and found in Massachusetts in 1915 — likely an aquarium release. Proceedings of the Rochester Academy of Science 15(3):206-212. CMS are originally from Asia. Ramshorn snail A Ramshorn’s whorled shell lays flat, unlike the protruding whorls of the Chinese Mystery Snail. The banded mystery snail is native to the southeastern part of the United States, from Florida and the Gulf of Mexico to the Mississippi River to Illinois. Mills, E. L., J. H. Leach, J. T. Carlton and C. L. Secor. Genetic and morphometric studies have established at least two new species, Viviparus limi (Ochlockonee Mystery Snail) and Viviparus goodrichi (Globose Mystery Snail), in FL and GA Atlantic drainages. Additional species are likely within this complex (Katoh and Foltz 1994). [10][13] Fecundity is generally between 4 and 81 young per female, but on average is closer to 11 young/female. EPA-600/3-80-068: 144 pp. [15] Reproductive females are usually larger than 16 mm. [2][10][11] In more open waters, fall migration begins earlier than in smaller lakes and ponds. [19] The New York State Museum has records from the 1950s and 1960s from 11 counties[5] Mackie et al. Funkhouser, and A.R. Freshwater Invertebrate Biology 1(4):2-17. Chinese mystery snail. It is often present with soft, silty and/or rocky substrates, but is present in a variety of habitats, including sand and detritus bottoms (Duch, 1976; Browne, 1978). It is a popular aquarium snail that’s been released in Minnesota. [20], In the Mid-Atlantic Region it is found in the Niagara River, Erie Canal, Hudson River drainage in New York, and possibly Lake Champlain. 1965. Later introductions were likely made via release from aquaria (Mills et al., 1993), but a one study found that this species is very resistant to desiccation, making it very capable of being dispersed over land via boat or other means (Havel et al., 2014). Nautilus 99(2-3):48-53. Individuals are generally found in waters with pH between 6.3 and 8.5. It is possible that some introduced populations could actually be V. viviparus, which is a European species that is indistinguishable from V. georgianus (Mills et al., 1993). There is not a lot yet known about these species, however, it appears that they have a negative effect on native snail populations. [2] Most growth generally occurs when waters become warmer in spring and summer, although reduced growth continues in winter.

Buckley, D.E. 1980. The freshwater snails (Mollusca: Gastropoda) of New York State. [10][12], It is dioecious (it has two distinct sexes), iteroparous (reproducing more than once in a lifetime) and ovoviviparous, laying eggs singly in albumen-filled capsules. The section is now dynamically updated from the NAS database to ensure that it contains the most current and accurate information. Viviparus georgianus often lives at high densities, sometimes up to 864/m2 (Lee et al., 2002; Pace and Szuch, 1985). Viviparus georgianus is a freshwater prosobranch (gills in front of heart) snail species complex with a thin and smooth shell, yellow-green in color with a straight outer lip, often with four distinctive brown bands present on the body whorl (Clench, 1962; Mackie et al., 1980). The shell can have 6 to 8 whorls. The species complex has a very variable shell morphology, and the shell bands are sometimes absent (Clench and Fuller, 1965), but, it always has an adextral (right-handed) shell with 3-5 inflated whorls separated by deeply indented incisions. banded applesnail, pondsnail, Vivipara contectoides. Watson, T.W. This species has been documented in high densities where present, and to be more successful in the north, further from its known native range (Dillon et al., 2006). Kate. 2002). Vail, V.A. In 2007, over 3,000 scaup and coots died in a Northern Wisconsin lake as a result of ingesting the infected, non-native snails, with many more birds unable to fly because of the infection. It is usually absent from larger, faster-flowing rivers (Katoh and Foltz, 1994); however, it can survive conditions of high water velocity in the St. Lawrence River, and may even be better adapted than the introduced Bithynia tentaculata (mud bithynia) to such habitat (Vincent, 1979). Bioremediation Journal 6(4):373-386. About Banded Mystery Snails Chinese mystery snails and banded mystery snails are non-native snails that have been found in numerous Wisconsin lakes.
