Adult shell about 4-5 mm high; umbilicus wide; columellar margin of the aperture concave in outline (Fig. Wm. The snails identified in Pasco County look different from the ones previously seen in Miami-Dade County: Their flesh is creamy white, rather than grayish brown. Planorbid snails are restricted to fresh water and occur worldwide, being found on all continental landmasses and many oceanic islands. It is represented in North America by Viviparus. Pomatiopsis lapidaria (Sowerby, 1878). (Thompson, 2000). Snails in wild populations range in shell color from yellow to brownish-black, and may contain stripes or dimpling. This causes problems in species identification and yield an undermeasure of the actual number of species that exist in nature. Campeloma geniculum Operculum calcareous with two pegs on inner surface (Figs. Burch, J. Freshwater mollusks of Alabama, Georgia and Florida from the Escambia to the Suwannee River. 200, 206).

Seminole Rams-horn Banded Mysterysnail It is hoped that this manual will stimulate other biologists to contribute to our knowledge of freshwater mollusks. 98). Quarterly Journal of the Florida Acaemy of Sciences, 32: 241-65. This will lead you to the final choice which identifies the snail. In others they are deposited in the water in gelatinous clusters. Black-crested Elimia) Elimia albanyensis (Lea, 1864). Biochemical studies show that in Elimia shell characters are conservative indicators of genetic divergence (Mihalcik & Thompson, 2002). Newborn shells white. 197-209). Physella gyrina aurea Shell usually opaque in adults, with a dark red callus inside the lip (Fig. Fossaria cubensis 92). 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. Shell short and stocky. This revision follows the classification proposed by Taylor. It could take years to fully rid the state of the species, officials say. Marsh Rams-horn Is non-native to the area, in our case northwest Florida Vertical ribs relatively strong and more widely spaced. (Thompson, 1968). 35). (Thompson, 1968). Outer lip nearly straight and parallel to axis of shell in adults (Fig. Aphaostracon asthenes Choctawhatchee Pebblesnail) Somatogyrus sp. Penis with 3 papillae along right margin (Fig. Aperture broadly attached to preceding whorl across parietal wall. Evolution has proceeded primarily through reproductive and trophic specializations. Click on the link in the row that best matches your snail. Another variety, with cream-colored flesh and mottled brown shells, was detected in 2022. Credit: Craig Pittman. 180-182). Color often glossy reddish brown. Graphite Elimia Subspecies bear the same name as the nominate subspecies, as is consistent with the standard used by the American Fisheries Society for fishes, and by other societies for other classes of animals. 19-21). Outer lip of aperture arched forward (Figs. Height of shell about 14-16 mm; width, 10-12 mm (Figs. In Florida, the African land snail existed largely in Miami-Dade County, although hundreds of the pests were found in Broward County, specifically western Davie, in 2014. . (Fig. Some species are dioecious with a normal representation of males and females. Pomacea paludosa 1-69. Shell usually with raised spiral threads around periphery, frequently the uppermost thread has conical or triangular spines (Figs. Click on images to enlarge them. NotogiIlia wetherby Taylor (2003) monographed the family Physidae. 87). Approximately 35 species have been described. 118). Shell dark brown. Penis with a single papilla along left margin (Fig. Ph.D. thesis, University of Michigan, i-xii, 1-324. Ferrissia is widely distributed in the northern hemisphere. They're different than the ones found previously. Only genera that enter fresh water are treated. In others, some or all populations may be parthenogenetic, consisting only of females, or they may have a disproportionately small number of males. In 2011, a population of the pests was discovered in Miami-Dade County. Florida authorities believe that the snail, native to eastern Africa, was reintroduced to the state when someone brought it home as a pet. 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. 180-193). Penis with 2 or 3 papillae on left margin (Fig. (Thompson, 1968). 109a, 109b).

The shells should be rinsed frequently in tap water during the cleaning process to prevent etching by the acid. (Say, 1829).

The best times to look for shells are after a high tide, after a storm, in the morning, and during the winter months. 1992. This family includes four North American genera, Amnicola, Dasyscia, Colligyrus and Lyogyrus, and the European genus Marstoniopsis and some Asian genera. The snails live in the bays and mudflats, but after they die their shells wash up on the beaches. Shell keeled or strongly angular at the periphery (Figs.

Operculum spiral, consisting of two or more rapidly increasing whorls (Fig. Apex fairly prominent as a rounded knob in the right posterior quadrant (Figs. Since then a great amount of fieldwork has taken place throughout Florida, and many additions to the fauna have come to light. Shell usually marked with red or rust-colored spots, flames, or bands (most apparent on juvenile specimens). 151, 152). Mantle mottled with black spots and blotches. Whorls of spire less rounded. Thompson, F. G. 1982. Until recently the entire knowledge of the Florida freshwater snail fauna was based on miscellaneous papers dealing with single species, groups of closely related species or single river systems. Most other genera have received relatively minor attention, and their systematics are in flux. Shell relatively thin. 129). 38). Clench, W.J., & R. D. Turner. (Fmr.)
