Fossaria cubensis (Thompson, 1968). Click on the link in the row that best matches your snail. 64). It should be remembered that it is only a key which emphasizes shell characters. Proc. 1905. (Lea, 1962). Outer lip straight in lateral profiles. Knobby Elimia Dipping them in a dilute solution of oxalic acid and gently scrubbing them with a fine brush can clean such specimens. In previous editions of the manual species of Floridobia were placed in the genus Cincinnatia. 86). Shell moderately large, 3.7-4.5 mm long; spire 1.00-1.35 times length of aperture; shell with 4.8-5.4 whorls. Shell with or without bands; slender; Suture deeply impressed; upper whorls with a strongly carinate periphery (Fig. The majority of these extinctions have been land snails from Pacific Islands and are the result of habitat loss the introduction of predators to isolated island groups. Female shell about 4-6 mm long (Figs. Thompson, F.G. 1968. 127); superior tubercles on penis arranged in oblique longitudinal series. Shell thin, fragile, very much depressed, less than 0.25 times as high as long. 45). Suture deeply impressed. According to the University of Florida, there are two common garden snails in the state -- the garden Zachrysia and the Banded Caracol. Shell elliptical in shape. Burch, J. Weak spiral striations present on top of growth striations (Figs. Umbilicus closed or narrowly perforate. Opercula should be glued to cotton plugs and replaced within the aperture. Adult size small, about 12-16 mm long (Fig. (Pilsbry, 1889). 1, 2). Shell small, 2.0-2.8 mm long. They also inhabit nearly all ecosystems. Fortunately in Florida, the species are relatively easy to distinguish. Clench, W.J. Umbilicus open, although very narrow in some species; occasionally closed. Earlier whorls of adult shell with vertical ribs and spiral chords. Hydrobiids are small- to medium-sized operculate snails that live primarily in brackish and fresh water. Shell conical, olivaceous in color. Over 500 species of Elimia have been described, most on the basis of shell characters. 162). Aperture rhomboid; baso-columellar angle extended as slight tonguelike projection; basal lip broadly but shallowly indented (Fig. Rock Springs Siltsnail Some tourists search for alligators, exotic birds or maybe even a ghost orchid. Dusky Ancylid Aperture elliptical and usually attached to preceding whorl; 4.1-4.5 whorls present. Evolution has proceeded primarily through reproductive and trophic specializations. Work through the questions, each time choosing the characteristic that best matches your snail from the two choices. Physella gyrina aurea Suture weakly impressed. Giant African land snails (GALS) could be devastating to Florida agriculture and natural areas because they cause extensive damage to tropical and subtropical environments. Seminole Rams-horn 180-182). Shell 2.8-3.7 mm long. Flatwood siltsnail Bayou Physa Apical whorls depressed; body whorl obtusely angular above and sharply carinated around funnel-shaped umbilicus. Florida is also home to a diverse variety of animal life, and while some species are native to the land, others are a dangerous threat to Floridaâ s delicately balanced ecosystem. Pomatiopsis lapidaria Live snails for shell studies should be preserved in 70 percent alcohol. Apex of shell slightly convex in outline. Penis with a single papilla along left margin (Fig. 37), which is important for generic and specific diagnosis. A single glandular crest present on apex of terminal lobe (Figs. (Goodrich, 1924). Even at that time, the author remarked that less was known about the land snails in Georgia than almost any other place in the eastern United States. Shell grayish-white. (Morelet, 1851). Choctaw Lioplax Brackish-water genera, Onobops and Heleobops, that are common in Florida are omitted. Indented Duskysnail Suture more deeply impressed than in 77a. Suture not as deeply impressed as in 77b. Shell unicolor brown, never mottled with reddish spots. The aquatic snail fauna of the southeastern United States has long been recognized for its richness and diversity. Definitive identifications may require anatomical dissections and reference to other literature. In 1976 in the St. Johns River 1 found Melanoides tuberculatus with population densities of 10,000/m2. 198, 205). Wm. Univ. The Wolf Snail was later introduced to many other Pacific islands in similar control efforts. The planorbid fauna of the southeastern states is particularly poorly known. Penny Sprite) Micromenetus floridensis (Baker, 1945). One to several dark growth-rest varixes usually present on last whorl. 63). Three other species occur farther north. Shell medium-sized, 3.0-3.8 mm long; thinner, translucent or transparent in life; tear-shaped; spire raised and nearly straight-sided, pointed; body whorl less conspicuously enlarged, not descending to aperture along last half whorl. As was anticipated, further work on the systematics of the southeastern freshwater snail fauna created the need for subsequent revision in 1999, and for this updated version. Color often glossy reddish brown. Haitia cubensis Body whorl rounded (Fig. The molluscan family Planorbidae. The number of subfanilies recognized in the Hydrobiida is unsettled. Sculpture consisting of fine incremental threads, and spiral striations that may become obsolete at maturity. Green Cove Springsnail Aperture relatively ample (Figs. (Fig. The Zachrysias Snail is a family of air-breathing land snails found throughout much of the tropics. 118). Floridobia petrifons In view of the inconsistency of these shell characters, these three forms may represent only a single species, Campeloma limum, which is widely distributed from the Escambia River system of Florida and Alabama east and north into North Carolina and Virginia. Shell elongate conical, spire high. Approximately 35 species have been described. 1969. 89). The HYDROBIIDAE include over 200 genera and approximately 1000 species. Thompson, F. G. 1997. Shell usually marked with red or rust-colored spots, flames, or bands (most apparent on juvenile specimens). Freshwater snails (Mollusca: Gastropoda) of North America. Outer lip nearly straight and parallel to axis of shell in adults (Fig. Conical Siltsnail 121). Shell specimens should be cleaned and air-dried. Scatter a few granulated menthol crystals on the water surface and allow the container to sit for 10-15 hours, at which time the snails should be extended from the shell and insensitive to probing with a needle. Rock Fossaria Elimia floridensis Shell unicolor, never banded. 145). 49, 50). Prominent minor spiral sculpture along periphery. Other families occur elsewhere in North America and in other continents. Surface smooth or dented with hammer marks. (Conrad, 1834). Pomacea paludosa Outer lip partially flattened in adults. Umbilicus open. Operculum with about 3 whorls (Fig. Rather stocky, adult about 15-20 mm long (Fig. Elimia dickinsoni Liguus, or Ligs, are arboreal snails occurring in southern Florida, Cuba, with a single species in western-most Haiti.The number of species involved depends on the people asked and the amount of beer consumed. (C.B. Curator of Malacology Aperture relatively shorter, about half or less the length of the shell. Bantam Hydrobe 126); accessory crest present on penis. (Pfeiffer, 1839). This subfamily includes about fifteen North American and European genera (Thompson 1979). It became increasingly important to provide an identification manual of the freshwater snails of Florida for many reasons. The specie prefer quite clear water, of lakes and backwaters of streams andsprings. Color uniform olive-green, never banded (Fig. These terrestrial mollusks vary from the size of a pinhead to wider than a quarter. Choctaw Lioplax Florida Applesnail Shell ovate, smooth or with fine raised riblets; riblets usually on the anterior slope when present. Elimia clenchi Adequate preservation begins when the specimens are collected. Last few whorls in large adults scalariform. Helisoma anceps anceps Length of shell 3.0-4.0 mm (Fig. Regal Hydrobe 62). Embryonic shell with a strong peripheral spiral chord that continues onto following whorls (Fig. Suwannee Hydrobe Operculum nearly multispiral with four large, slowly expanding whorls (Fig. Ichetucknee Siltsnail Penis without a conspicuously enlarged papilla near right base, although other papillae usually are present. Other species deposit eggs during the period of March through May, at which time the adults die and immature forms dominate the population through August or September. (Linnaeus, 1758). 1918. Shell elongate-conical; 10-40 mm long in adult specimens; apex of spire usually eroded; shell with 8-12 whorls although eroded specimens may have fewer; shell usually strongly sculptured with spiral and/or vertical ribs and threads (except in Elimia dickinsoni); central tooth of radula without basal or lateral cusps (Fig. Vernacular names are given only for species. Penis of males with papillae along sides (Figs. U-shaped superior crest not enclosing longitudinal crests. Umbilicus closed. 3). 70, 71). Three species are known from rivers entering northwest Florida from Georgia and Alabama. These snails could be devastating to Florida agriculture and natural areas as they cause extensive damage to tropical and subtropical environments. Aperture trapezoidal in shape; spire more robust, straight sided; with a shallower suture; parapical crest large (Fig. Peristome narrow to broadly ovate. Pilsbry, H. A. Last whorl not shouldered (Figs.155, 156). Formalin will corrode the shell and thereby eliminate color, delicate sculpture, and the periostracum — the thin “skin” coating present on most shells. 131). Clench, W.J., & S. L. H. Fuller. Shell sexually dimorphic in size, males about one-third as long as females. 158). Spiral or costate sculpture usually present. Shell globose with a relatively depressed spire; about 1.0- 1.2 times as high as wide. Inferior crest usually present. About 4.2-4.6 weakly arched whorls with a weakly impressed suture. This causes problems in species identification and yield an undermeasure of the actual number of species that exist in nature. Planorbella trivolvis intertexta 11). Basch (1963) revised the classification and recognized only twelve species. The giant African land snail is one of the most damaging snails in the world, consuming at least 500 different types of plants. Micromenetus dilatatus avus (Pilsbry, 1905). POMATIOPSIDAE Adult shells about 40-60 mm high (Fig. 1978. Penis with 3 – I 0 small papillae around base and 7-15 papillae along right margin in a single row (Fig. 68). 124). 16, 25, 28). Shell without conical spines, although spiral threads may be present. Zachrysia auricoma (Férussac, 1821) Southern Flatcoil. (Vanatta, 1934). The family contains many genera and numerous species in South America, Central America, Mexico, Africa, and Southeast Asia. Floridobia porterae Spire usually about equal to or greater than height of aperture (Figs. A review of the aquatic gastropod subfamily Cochliopinae (Prosobranchia, Hydrobiidae). 141). 1956. Polygyra septemvolva Say, 1818. The primary differences between the two families are based on soft anatomy. Shell elliptical-ovate in shape. Peristome incomplete around aperture. Ampullariids have been referred to as PILIDAE in earlier editions of this manual. Campeloma geniculum (Conrad, 1834) is readily recognized by its obese, solid shell; it usually has a normal proportion of males in its populations, although some populations are apomictic parthenogens. NotogiIlia wetherby Planorbula armigera wheatleyi Shell sculptured with prominent nodes overlapping suture and forming crenulations. Shell rounded at the periphery (Figs. Nuclear whorl flattened, 0.41-0.48 mm in diameter transverse to initial suture. 1982. Among the most beautiful snails are the Florida Tree Snails of the genus Liguus.Few groups of molluscs have such a storied past. 1918. 6). Gainesville, Florida 32611-7800. Base of last whorl with prominent spiral ridges. Hood Ancylid Length of shell 2.0-2.5 mm (Fig. Floridobia mica 16, 17). (Clench & Turner, 1956). 69).

Upon returning home, I photographed the snails and by way of George Holm, passed the photos along to Dr. Harry Lee, a land snail expert with the Jacksonville Shell Club. Nautilus, 19: 34. (Conrad, 1834). One species, Spilochlamys turgida (Thompson, 1969), the Pumpkin Siltsnail (Fig. Suture more deeply impressed. Most inhabit fresh water, but some also occur in brackish water. Penis simple, elongate-conical, without papillae (Fig. 140). 93). Spire raised and flat-topped. Bulletin of the Florida State Museum, Biological Sciences, 1: 97-239. Prominent vertical ribs on middle and upper whorls. Shell usually opaque in adults, with a dark red callus inside the lip (Fig. This study was a landmark contribution to the malacology of the southeast, and it summarized the known fauna of western Florida. Haitia pomilia pomilia Marginal teeth of radula trapezoidal with well-differentiated cusps. It is represented in North America by Viviparus. Native to East Africa, the giant snails were first imported to this country as pets and educational props in 1966. 169).
