Identification KeysThese files are all keys for the identification of various kinds of organisms. The rosy wolfsnail was introduced into Hawaii in 1955 as a biological control for the invasive . Aperture narrowly in contact or free from preceding whorl. Most inhabit fresh water, but some also occur in brackish water. (Thompson, 1968). Color of fresh shell never milky white. 2018). 75). Two occur in Florida. A Guide to Florida Bird Species. It has many colorful stripes, colors, and bands on its shell which are usually orange, light orange, dark orange, or yellow. A taxonomic revision of the feshwater snails referred to as Elimia curvicostata, and related secies. Knobby Elimia Freshwater snails (Mollusca: Gastropoda) of North America. Hyacinth Siltsnail) Floridobia floridana (Frauenfeld, 1863). Rhapinema dacryon 159). (Thompson, 1968). Aperture broadly in contact with preceding whorl. 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. 24, 27). Mantle spotted with black, shaded or unmarked; terminal lobe of penis with complex crests that cause it to look like an animals head; flagellum slender, with scattered and discontinuous glands along edge (Figs.

Marsh Sprite Is non-native to the area, in our case northwest Florida Live snails for shell studies should be preserved in 70 percent alcohol. Shell conical to elongate-conical; whorls 4.0-4.5 with a deeply impressed suture. The species are highly variable, and there is no consensus regarding the number of valid species. 200, 206). Body whorl relatively narrow, not conspicuously enlarging near aperture (Fig. 1991. (Mihalcik & Thompson, 2002). Apex in about middle of shell. Terminal lobe of penis slender. Excentric Ancylid Thiarids are found in tropical and subtropical regions of the world. 16, 25, 28). It became increasingly important to provide an identification manual of the freshwater snails of Florida for many reasons. Seminole Siltsnail Spilochlamys is most similar to the next genus, Cincinnatia, from which its shell usually differs by having a more deeply impressed suture, more strongly shouldered whorls, and a wider umbilical perforation. (Clench, 1925). Most freshwater hydrobiids in the eastern United States are annual species. 107, 108). Shell moderately elevated, over 0.25 times as high as long.

Length of shell 2.2-2.6 mm (Fig. 199). (Thompson, 1968). Shell usually corpulent, brown or green, generally opaque, but occasionally translucent in juveniles. The spire differs between bumpy and smooth but it is always elongated. Escambia Elimia The latter genus includes a single species, Cincinnatia integra (Say, 1817). Three species in Florida were introduced from Southeast Asia. Taylor recognizes twenty-three genera based on the soft anatomy. Tryonia aequicostatus Floridobia fraterna Suture relatively shallow. Opercula should be glued to cotton plugs and replaced within the aperture. Shell brightly banded and with large, wide and wavey vertical folds; robust, usually 21-25 mm long (Fig. 87). Various species of Cipangopaludina also have been introduced from the Orient into North America. Penis simple, elongate-conical, without papillae (Fig. Aperture broadly ovate in shape; parietal wall weakly in contact or solute from body whorl; whorls more prominently arched and with a deeper impressed suture. Essentially identical shells occur repeatedly among unrelated genera and subfamilies. 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. The coloration of the aperture and the embryonic shell is not consistent within single population samples, and the contour of the outer lip is highly variable within single drainage systems and with the age of the specimens examined. Operculum with about 6 slowly expanding whorls (Fig. It wasn't until 2021 the population was. Mimic Pondsnail From a distance, the snail kite generally resembles a medium-sized hawk with broad wings. 33); males without copulatory structures.

Shell light brown and frequently mottled with rust-colored spots that may form a spiral row below the suture. Pomacea canaliculata 180-182). (Thompson, 1968). Many species are secondarily modified to appear right-handed or pseudo-dextral (FIGS. By 1973, more than 18,000 snails had been found and destroyed along with thousands of eggs, and the snail was . Generally with distinct axial and spiral striations. 5: 1-140. Body whorl strongly keeled as though pinched at the periphery (Figs. 135). Oftentimes you'll see trails of mucous around these damaged sites. Snails have invaded some local areas throughout northern Santa Rosa and Escambia Counties this summer. Aperture free from, or only in slight contact with, preceding whorl. The aquatic snails of the Family Hydrobiidae of peninsular Florida. Shell cap-shaped or limpet-like with a wide, open aperture forming base of shell (Figs. Penis as illustrated (Fig. The planorbid fauna of the southeastern states is particularly poorly known. A little practice may be necessary to perfect this relaxing procedure. The snails live in the bays and mudflats, but after they die their shells wash up on the beaches. 1918. As of last . Laevapex is a North American genus. Lioplax pilsbryi choctawhatchensis Penis with papillae along both margins, or right margin only (papillae absent in some Aphaostracon). Only three widely distributed species occur in Florida. Purple-throated Campeloma Adult large, about 23-27 mm long (Figs. Shell ovate or subcircular in shape, smooth or with radial sculpture localized anteriorly. Aperture strongly oblique. This snail was twice established in southeastern Florida and was successfully eradicated both times. POMATIOPSIDAE There have been introductions of this species into Argentina, the Atlantic Islands, Australia, Chile, Haiti, Mexico, New Zealand, and . Apical whorls raised to form a point on top of spire. Gulf Coast Pebblesnail) Somatogyrus walkerianus (Aldrich, 1905). Outer lip of aperture strongly sinuous in lateral profile (Fig. Includes the limpkin, a Sunshine State specialty. Applesnails are tropical to subtropical organisms and cannot survive below 50F in the winter (Florida DOACS, 2002). 1918. Female ovoviviparous with about 50 embryos in uterus; embryos clearly evident through clean shells. Aphaostracon pachynotus The following key includes all of the species that occur in Florida and some that occur in Alabama, Georgia, and South Carolina. The Florida Department . Female shell about 4-6 mm long (Figs. Average length about 5 mm (Figs. Shell conical, thick, opaque. NERITIDAE Base of last whorl with prominent spiral ridges. Spire usually about equal to or greater than height of aperture (Figs. Base of shell when viewed from below showing about half of preceding whorl due to straight basal lip (Fig. Identify your shells using our popular photo guide to southwest Florida shells from Sanibel Island and beyond. Parietal margin of operculum slightly convex in outline (Fig. Penis with a large, blade-like flagellum with continuous heavy dermal glands along each side (Figs. Many North American snail species were described near the turn of the century by Walker (1918). The focus on most investigations was on rivers north of Florida, and little attention was given to the Florida fauna. Fingers crossed, it'll stay that way. (Fig. 128). (Thompson, 1968). Nautilus, 19: 34. Some hydrobiid snails from Georgia and Florida. Davis, G.M., M. Mazurkiewicz, & M. Mandracchia.

Shell nearly smooth, sculptured with irregularly spaced incremental striations (Figs. 203, 209). Penis with a single papilla along left margin (Fig. Walker, B. 149). For the purpose of completeness, the three parthenogenetic forms and C. geniculum are included in the key. Size small I I to medium, 8-12 mm in length. 202, 208). Shell globose with a short depressed spire; body whorl ample; umbilicus closed. 36); males with a copulatory appendage, a penis (Fig. (Say, 1829). They are commonly found on live aquatic plant stems, dead leaves and sticks, and on bottles and cans. Goldenhorn Marisa Penis with 3 papillae along right margin (Fig. Spiral or costate sculpture usually present. 171-173). Identification should conform with all data in the key and with geographic distributions. 99). Shell conical; thin and transparent; 4.0-4.5 strongly arched whorls. 15, 18).

The most recent sighting of a giant African land snail took place in 2017, meaning the species can now be considered eradicated in the state of Florida. Operculum paleomelanian, with a large sub-centrally located nucleus (Fig. Brownish-yellow in color (Fig. Average length about 4 mm (Figs. 39). Bulletin of the Environmental Protection Agency, EPA-600/3-82-026: i-vi, 1-294. Columellart margin of aperture not flat-faced; apex of shell usually entire; penis with large terminal lobe on left side and small appendage-like flagellum on right margin (Fig. Apex of shell slightly convex in outline. CLICK ON EACH PHOTO Fallen Angel Wing -Atlantic Mud Piddock Boring Angel Wing- Striate Piddock Rice Olive Clifton Spring Hydrobe It also was the first adequately illustrated faunal summary published on the Southeast. Additional surveys found four different populations all associated with the CSX railways. Outer lip of aperture with a thick callus on inner surface. In Pasco County Florida, a quarantine order was issued for people after the re-discovery of the giant African land snail, an invasive species that can harm to humans, structures, and wildlife. The reappearance of an invasive snail species forced state officials to enact a quarantine order two weeks ago for residents of Florida's Pasco County, an area north of Tampa along the gulf. Sculpture consisting of axial striations only (Fig.147).
