Pleurocera is a genus of freshwater snails with an operculum, aquatic gastropod mollusks in the family Pleuroceridae.
Pleurocera is the type genus of that family.
All members of the genus Pleurocera are native to eastern North America.
All of the species in this genus have thick-walled high-spired shells, and some attain a length of over 4 cm. The shape of the shell is elongate-conic or cylindrical. The sculpture of the shell is often carinate or costate. The shell of larger species sometimes develops sculpturing and a small siphonal canal or siphonal notch at the base of the aperture.
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.
Species within the genus Pleurocera include: (brackets needs to be checked, authorities according to the IUCN Red List may be incorrect)
