Description
The ovate clubshell is an oval or elliptical mussel that is around 5 cm (2 in) in length. The umbo is inflated, and the posterior ridge is well-developed. The shell color is yellow to dark brown, sometimes with broad green rays. The nacre is white to bluish-white.
Range & habitat
The species prefers sand and gravel substrates in riffles, runs, and shoals of creeks and rivers. Females are gravid (pregnant) in June to July. The species, like most freshwater mussels, requires a host fish for its parasitic larval phase. The host fish for Pleurobema perovatum have not been studied, but other members of the genus use minnows in the Cyprinidae family.

In human culture
The genus name Pleurobema comes from the Greek "side" and "step", referring to the well-defined posterior ridge. The species name perovatum means "very oval".
