Ptychobranchus occidentalis is a species of freshwater mussel in the family Unionidae, the river mussels. It is endemic to the United States,[1] where it is known from Arkansas, Kansas, Louisiana, Missouri, and Oklahoma. Its common name is Ouachita kidneyshell.[2]

This mussel packages its larvae, or glochidia, in a membranous conglutinate which resembles a small prey item. When a fish comes to investigate this lure, the glochidia attach to its gills and use it as a host during their development.[3]
