Campeloma limum 115a, 115b). Shell with darker colored spiral chords that may be smooth or wavy. Lip of adult shell usually with a thick crest externally and an internal callus. Spire long, 1.3-1.7 times length of aperture, convex in outline; shell relatively large and nearly cylindrical; 4.0-4.9 mm long; whorls 5.0-5.7, strongly rounded with a deeply impressed suture (Fig. Four species currently are recognized, but the genus has received very little study over most of its range. Shell cylindric-conical with 4.5-5.0 whorls. Some recent additions to the British list which are still very rare are mentioned as a note next to the species as which they would probably key out. One of the largest and most damaging snails on Earth, giant African land snails (GALS) first invaded southern Florida in the 1960s. One species, C. chinensis malleatus (Reeve, 1863) (Fig. The aquatic snail fauna of the southeastern United States has long been recognized for its richness and diversity. (Pilsbry and Beacher, 1892). Color of fresh shell never milky white. Nat. The Pleurodontidae (superfamily Helicoidea) is a family of air-breathing land snails found throughout much of the tropics. POMATIOPSIDAE Sexes strongly dimorphic in size, males about half as long as females. 169, 172). (Dall, 1885). 151, 152). Acad. Three other species occur farther north. dalli Shell cylindric-conical, solid opaque; 4.5-4.9 moderately rounded whorls. 4, 5). Terminal lobe of penis slender. Thompson, F. G. 1969. Snails were brought to the U.S. from Europe in the 1850, with the idea that they would be a … The radula can be studied by dissecting out the buccal mass and macerating it in clorox or sodium hydroxide. Floridobia vanhyningi Shell ovate, smooth or with fine raised riblets; riblets usually on the anterior slope when present. Shell elongate. Penis with 7-50 papillae along right margin and 1-4 papillae along distal third of left margin (Figs. 99). (Linnaeus, 1758). (Thompson, 1968). Whorls of spire pointed and scalariform (steplike with nearly flat shoulders and deep sutures). Rotund Mysterysnail Shell with prominent ribs and spiral chords on all whorls. Newborn young about 4.5 mm in diameter (this can be determined by removing juveniles from brood pouch). Outer lip nearly straight and parallel to axis of shell in adults (Fig. 1980. Penis with large papilla on right margin near base and one or two papillae on left margin near distal end (Figs. Mesa Rams-horn Prominent vertical ribs on middle and upper whorls. 141). Some hydrobiid snails from Georgia and Florida. Magic cone sea snail poison has roughly 50,000 different components, referred to as conotoxics. Never preserve shell specimens in formalin. Apex with fine radial striations (Figs. Penis with 4-6 papillae along right margin (Fig. One species occurs naturally in Florida, and three others have been introduced. After the shells are thoroughly rinsed, they can be air-dried in cardboard trays. Elimia annae Shell more slender, about 0.30-0.35 times as wide as high. Newborn shells white. Outer lip less sinuous. Average length about 4 mm (Figs. Adams, 1841). (Thompson, 1968). Shell with 5.0-6.5 whorls; about 3-5 mm long (Fig. (Weatherby, 1879). About fifteen species have been described from North America. The bodies of large snails, such as viviparids and pilids, should be pulled from the shell. Dipping them in a dilute solution of oxalic acid and gently scrubbing them with a fine brush can clean such specimens. (Gould, 1841). 1979b. 204-207), often eroded in older specimens. Shell glossy. B. Apex of shell slightly convex in outline. Size smaller than last species, seldom exceeding 10 mm in width (Figs.194-196). Aperture without serrate denticles on parietal wall. 80). Conus magus. 174-176). It became increasingly important to provide an identification manual of the freshwater snails of Florida for many reasons. Peristome complete around aperture. Adult shells about 40 – 70 mm high (Fig. One of the most infamous examples of this is the introduction of Florida’s Rosy Wolf Snail, a predator of other snails, brought from Florida to the Hawaiian Islands to try and control populations of the Giant African Snail that had been accidentally brought to Hawaii in the 1940s. Lymnaeids are a nearly cosmopolitan family of freshwater snails. Aperture elliptical and usually attached to preceding whorl; 4.1-4.5 whorls present. Armored Siltsnail The family contains numerous genera and species, some of which are important medically as intermediate hosts for trematode parasites. 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. In 1976 in the St. Johns River 1 found Melanoides tuberculatus with population densities of 10,000/m2. Incremental striations uniformly weak. Elimia dickinsoni 19-21). Eight species have been proposed. Female ovoviviparous with about 50 embryos in uterus; embryos clearly evident through clean shells. Shell globose with a relatively depressed spire; about 1.0- 1.2 times as high as wide. Vertical sculpture reduced to irregularly spaced and uneven growth striations or low undulating ribs. (Mihalcik & Thompson, 2002). 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. 10-12). Shell elliptical-ovate in shape. Snails and Slugs. Malacological Review, 24: 55-72. Shell unicolor, with distinct vertical sculpture in addition to strong spiral sculpture. (Thompson, 1968). However, this appears to be an over reduction, and several southern species were synonymized that appear worthy of recognition. Basal lip of peristome deeply receded. J. Clench and Ruth P. Turner (1956) published a survey of the fauna from the Suwannee River west to the Escambia River. (Lamark, 1822). 146). Conical with relatively obese whorls. Amnicola dalli. Black-crested Elimia) Elimia albanyensis (Lea, 1864). Click on images to enlarge them. Mantle diffusely pigmented with melanophores (Fig. Vertical ribs smooth along the periphery, strongly developed (Fig. Penis with 0-6 papillae confined to right margin (Figs. Shell sculpture with incremental striations only. Shell coiled to the right, with the aperture on the right side (Figs. Shell unicolor, never banded. Adults 9-15 mm wide (Figs. Earlier whorls of adult shell with heavy vertical ribs crossed by knobby folds or a strong spiral chord; sides of spire straight or weakly convex in lateral profile; embryonic shell with a single spiral chord on periphery and heavy vertical ribs, but without basal spiral chord (Fig. The LIOPLACINAE is endemic and include Campeloma, Lioplax, and Tulotoma. Fossaria modicella Small- or medium-sized snails need to be identified with the aid of a binocular dissecting microscope that is equipped with an ocular micrometer calibrated to 0.1 mm accuracy so that precise measurements can be made. The family attains its greatest diversity in Southeast Asia. It should be remembered that it is only a key which emphasizes shell characters. Penis with a few simple scattered superior tubercles on outer surface; parapical crest on a low ridge; accessory crest and inferior crest absent (Fig. Widely umbilicate. (Walker, 1908). 116a, 116b). They also inhabit nearly all ecosystems. 56). 1918. The Pleuroceridae of the Atlantic Coastal Plain. (Clench & Turner, 1956). 37), which is important for generic and specific diagnosis. With continuous heavy dermal glands ( Fig egg-laying groove or sinus on right margin and 1-4 papillae along third., 1864 ) a manual for identification, but that is unimportant for anatomical purposes lip of adult shell prominent.
