Shell description

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

Distribution

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]

Ecology

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

gollark: Or, well, very genetic.
gollark: Also, <@341618941317349376>, just because intelligence is somewhat *heritable*, doesn't mean it's *genetic*.
