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. 1981. 1976. Mackie, G. L., D. S. White and T. W. Zdeba. This species is found in freshwater low-flow lentic streams, lakes, and ponds. This species is considered established in the waterbodies in which it introduced. Viviparus georgianus was originally discovered and described (under the name Paludina georgiana) by Isaac Lea in 1834.[1]. There is not a lot yet known about these species, however, it appears that they have a negative effect on native snail populations. Szuch. The Banded Mystery Snail Chinese mystery snails and banded mystery snails are non-native snails that have been found in numerous Wisconsin lakes. Duch T. M. (1976). 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.

[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. 2002; Mackie et al., 1980). For queries involving fish, please contact Matthew Neilson. This snail is found in lakes and slow-moving rivers with mud bottoms. It is often the dominant member of the macrofauna in its trophic level, both in number and function (Browne, 1978). Chinese mystery snail. Banded mystery snails are smaller than the Chinese mystery snail. 1976. 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). The natural history of an ovoviviparous snail Viviparus georgianus in a soft water eutrophic lake. Snails as biomonitors of oil-spill and bioremediation strategies. The species thrives in eutrophic lentic environments such as lakes, ponds and some low-flow streams. http://fwgna.blogspot.com/2007/11/ducks-snails-and-worms-when-invasive.html. 2002). 1985. Mills, E.L., J.H. Nonindigenous Aquatic Species Database. 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). [22], This article incorporates public domain text from references.[1][21]. [7][19], A recent study found that Viviparus georgianus is in fact not one species, but a species complex in North America. Remarks.—This species, in form, resembles most, perhaps, the P. vivipara. 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. Identification, occurrence and ecology of species. Viviparus georgianus (I. Lea, 1834) Common name: banded mysterysnail. Viviparus georgianus is known to be a facultative, or even obligate, filter-feeding detritivore (Browne, 1978; Lee et al., 2002). 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). Mills, E. L., J. H. Leach, J. T. Carlton and C. L. Secor. Parasite has killed thousands of scaup. The Nautilus 90(1):7-10. The only time mystery snails feed on lives plants is when other sources aren’t available. Strayer, D. 1987. Jokinen, E.H., J. Guerette, and R.W. Occasional Papers on Mollusks 2(27):261-287. 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). 1993. In more open waters, fall migration begins earlier than in smaller lakes and ponds (Lee et al., 2002). Hab. Environmental Research Laboratory, Office of Research and Development, U. S. Environmental Protection Agency, Duluth, Minnesota 55804. The banded mystery snail (Viviparus georgianus, pronounced vi-vi-PAIR-us jor-jee-AN-us) is native to the southeastern US. [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. This species is very similar to the European Viviparus viviparus. Jokinen, E. H., J. Guerette and R. W. Kortmann. A Mystery Snail is a freshwater aquarium snail often available in pet stores. 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. UNORGANIZED TERRITORY All snails found at this location, Chinese Mystery, Banded and or Faucet. This information is preliminary or provisional and is subject to revision. Variation in capsule albumen in the freshwater snail Viviparus georgianus. How did it get its name? 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). Ecology and zoogeography of the freshwater mollusks of the Hudson River Basin. comm., July 24, 2018). Other records are from 1931 near Buffalo, Lake Erie and the Niagara River. Table 1. 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). Buckley, D.E. Since then, they have spread throughout southern Ontario. There is not a lot yet known about these species, but they seem to have a negative effect on native snail populations. Banded Mystery Snail (Viviparus georgianus. 1982. 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 outer shell is light to dark olive green to brownish. The banded mysterysnail and Chinese mystersnail are both distributed from the Niagara River, flowing into the Great Lakes. Mackie, G.L., D.S. covering In the Severn Sound Banded mystery snails are small animals with a coiled spiral shell. 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). 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. Mystery Snail Tank Requirements. Clench, W.J., and S.L.H. Aspects of the feeding habits of Viviparus georgianus. A guide to freshwater mollusks of the Laurentian Great Lakes with special emphasis on the genus Pisidium. The Channeled apple snail has not yet been recorded in Ontario, but is found in southern parts of the United States. Additional species are likely within this complex (Katoh and Foltz 1994). † Populations may not be currently present. [21] It is established in the Chesapeake Bay, Maryland. 1986. Carlton, and C.L. Mystery Snail shells can be a solid color, have a color gradient, or have accents of … [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. I have 7 varieties of MYSTERY SNAILS for Freshwater Aquariums. [2] Most growth generally occurs when waters become warmer in spring and summer, although reduced growth continues in winter. [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 operculum (“trapdoor”) is concentrically marked, with uniform color throughout, and no banding. The banded mystery snail may prey on fish embryos. 1978. Pace, G.L., and E.J. This species is also similar in shell shape and distribution with Viviparus intertextus and Viviparus subpureus (K. Cummings, Illinois Natural History Survey, pers. 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. [19] The New York State Museum has records from the 1950s and 1960s from 11 counties[5] Mackie et al. Funkhouser, and A.R. Biological Journal of the Linnean Society 53(1):73-90. (Smith, 2007). Biological Journal of the Linnean Society 27(4):293-310. Japanese and banded mystery snails are only known from a few locations in Michigan, while Chinese mystery snails have been found in several inland lakes over the past few years. A catalogue of the Viviparidae of North America with notes on the distribution of Viviparus georgianus. The Japanese variety of this species is black and usually a dark green, moss-like alga covers the shell. Lea) Description: The banded mystery snail is a member of the family Viviparidae. American Malacological Bulletin 35(2):175-180. [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. It is a popular aquarium snail that’s been released in Minnesota. 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. Mystery Snails. Wade, J.Q. Kate. 1965. Ramshorn snail A Ramshorn’s whorled shell lays flat, unlike the protruding whorls of the Chinese Mystery Snail. Resistance to desiccation in aquatic invasive snails and implications for their overland dispersal. [15] Reproductive females are usually larger than 16 mm. For queries involving invertebrates, contact Amy Benson. [18] Massachusetts, Indiana and Connecticut are probably some of the states marking the northern limit of this species’ native range. Banded Mystery Snail Select Another Location: Total Locations: 536 Total Lakes and Rivers: 558 * Disclaimer: Aquatic invasive species (AIS) records are assigned statuses of "verified", "observed", or "no longer observed" based on AIS Status Guidance. Seasonal reproductive patterns in 3 viviparid gastropods. Because some populations of the banded mysterysnail are semelparous (dying off after one breeding event), this can create a large concentration of dead snails in habitats and leave behind significant shell debris (Dillon et al., 2006). 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. Hopeton, near Darien, Georgia. Banded Mystery Snail Select Another Location: Total Locations: 503 Total Lakes and Rivers: 557 * Disclaimer: Aquatic invasive species (AIS) records are assigned statuses of "verified", "observed", or "no longer observed" based on AIS Status Guidance. The bands may be hidden by algae or sediment. Proceedings of the Rochester Academy of Science 15(3):206-212. The shell of the Chinese mystery snail is large, spherical, and smooth. 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 … This invasive species is suspected to harm native snails and lab studies found it may prey on fish larvae, reducing survival rates. It is historically native to Florida and Georgia among other southeastern states. (1980) list this species as recorded from Lake Huron, but they do not give the date of establishment, or any references. Species: mattea The Pale Banded Snail (Figuladra mattea) has, as the common name suggests, a pale, yellowish shell with many strong, dark brown spiral bands. The shell is up to 1.5 inches tall, and 1-1.5 inches wide. Proceedings of the Rochester Academy of Science 13(1):17-22. 1980. Leach, J.T. The shell opening is on the right when the shell is pointed up. 2002. Jokinen, E.H., and J. Pondick. [16] Female banded mystery snails live 28 – 48 and males live 18 – 36 months. http://www.fwgna.org/species/viviparidae/v_georgianus.html. One thing’s for sure- they love areas with decomposing or dead plants. 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). The shell can have 6 to 8 whorls. [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. Bulletin of the American Malacological Union, Inc. 43:90. 1994. [2][12][13] Females generally brood eggs for 9–10 months. The banded mystery snail (Viviparus georgianus) is one non-native invasive species that receives little attention. Horizontal brown bands … 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.
