Ptychobranchus

Ptychobranchus is a genus of freshwater mussels in the family Unionidae.

Species of this genus package their larvae, known as glochidia, in conglutinates that resemble prey items such as fish fry. As fish come to investigate these lures there is a better chance the glochidia will contact them, attach, and use them as hosts during development.

Species include:
 * Ptychobranchus fasciolaris – kidneyshell
 * Ptychobranchus foremanianus
 * Ptychobranchus greenii – triangular kidneyshell
 * Ptychobranchus jonesi – southern kidneyshell
 * Ptychobranchus occidentalis – Ouachita kidneyshell
 * Ptychobranchus subtentum – fluted kidneyshell
