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.

Shell description[edit]

The shell can have up to 14 whorls. The shell of this species can be as long as 37 mm.[1]


Pleurocera acuta is native to the United States. It occurs in the Ohio River and Great Lakes drainages; the Mississippi River west to Kansas and Nebraska.[1]

This species is listed as threatened in some Midwestern states.[1]

The nonindigenous distribution of Pleurocera acuta includes the Lower Hudson River drainage and Oneida Lake in New York State. It was introduced there, probably via the Erie Canal.[1]


This species is found in freshwater rivers and streams where it burrows in sand and mud. Eggs are laid in the spring.[1]
