Shell description

The shell can have up to 14 whorls. The shell of this species can be as long as 37 mm.^[4]

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.^[4]

This species is listed as threatened in some Midwestern states.^[4]

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.^[4]
