Pleurocera is a genus of freshwater snails with an operculum, aquatic gastropod molluscs in the family Pleuroceridae. [2]
Pleurocera is the type genus of that family.
All members of the genus Pleurocera are native to eastern North America. [3]
All of the species in this genus have thick-walled high-spired shells, and some attain a length of over 4 cm (1.6 in). The shape of the shell is elongate-conic or cylindrical. [3] The sculpture of the shell is often carinate or costate. [3] The shell of larger species sometimes develops sculpturing and a small siphonal canal or siphonal notch at the base of the aperture. [3]
Opercula are paucispiral and corneous, but may be vestigial in some species, not completely closing the aperture.
The soft parts of the animal usually have a gray or brown coloration, commonly speckled with orange. The similar genus Juga has a seminal receptacle, but Pleurocera has no seminal receptacle. [3]
Species within the genus Pleurocera include: [2] [4]
Pleurocera gonulaRafinesque, 1831 (nomen dubium)
Littorinimorpha is a large order of snails, gastropods, consisting primarily of sea snails, but also including some freshwater snails and land snails.
Planorbidae, common name the ramshorn snails or ram's horn snails, is a family of air-breathing freshwater snails, aquatic pulmonate gastropod molluscs. Unlike most molluscs, the blood of ram's horn snails contains iron-based hemoglobin instead of copper-based hemocyanin. As a result, planorbids are able to breathe oxygen more efficiently than other molluscs. The presence of hemoglobin gives the body a reddish colour. This is especially apparent in albino animals.
Physella is a genus of small, left-handed or sinistral, air-breathing freshwater snails, aquatic pulmonate gastropod mollusks in the family Physidae.
Physa is a genus of small, left-handed or sinistral, air-breathing freshwater snails, aquatic pulmonate gastropod mollusks in the subfamily Physinae of the family Physidae.
Campeloma is a genus of gilled operculate freshwater snails in the family Viviparidae.
Elimia is a genus of freshwater snails with an operculum, aquatic gastropod mollusks in the family Pleuroceridae. Various species are found in creeks throughout much of the eastern and central United States and the Great Lakes region of Canada. They were formerly included in the genus Goniobasis, together with the western Juga species.
Elliptio is a genus of medium- to large-sized freshwater mussels, aquatic bivalve mollusks in the family Unionidae, commonly known as the unionids, freshwater mussels or naiads.
Leptoxis is a genus of freshwater snails with a gill and an operculum, aquatic gastropod molluscs in the family Pleuroceridae.
Pleuroceridae, common name pleurocerids, is a family of small to medium-sized freshwater snails, aquatic gilled gastropod mollusks in the superfamily Cerithioidea.These snails have an operculum and typically a robust high-spired shell.
Crepidula, commonly known as the slipper snails, slipper limpets, or slipper shells, is a genus of sea snails, marine gastropod mollusks in the family Calyptraeidae. This family includes the slipper snails (Crepidula), hat snails (Calyptraea), spiny slipper snails (Bostrycapulus), and cup-and-saucer snails (Crucibulum) as well as Crepipatella, Siphopatella, Grandicrepidula, and Maoricrypta.
Pleurocera acuta, common name the sharp hornsnail, is a species of small freshwater snail with a gill and an operculum, an aquatic gastropod mollusk in the family Pleuroceridae, the hornsnails.
Fasciolariidae is a family of small to large sea snails, marine gastropod mollusks in the superfamily Buccinoidea. Species in Fasciolariidae are commonly known as tulip snails and spindle snails.
Doris is a genus of sea slugs, specifically dorid nudibranchs. These animals are marine gastropod molluscs in the family Dorididae.
Fissurella is a genus of small to medium-sized sea snails or limpets, marine gastropod mollusks in the subfamily Fissurellinae of the family Fissurellidae, the keyhole limpets.
Stomatella is a genus of small to medium-sized sea snails, marine gastropod mollusks in the family Trochidae, the top snails and their allies.
Thiara is a genus of freshwater snails, aquatic gastropod mollusks in the subfamily Thiarinae of the family Thiaridae.
Vermetus is a genus of sea snails, marine gastropod mollusks in the family Vermetidae, the worm snails or worm shells.
Polymesoda is a genus of clams in the family Cyrenidae. They were previously in the family Corbiculidae, before it was subsumed into Cyrenidae.
Rotundaria is a genus of freshwater mussels, aquatic bivalve mollusks in the family Unionidae, the river mussels.
