The purple cat's paw pearlymussel is one of our rarest freshwater mussels and it is truly on the brink of extinction. When listed in 1990, some live adults could be found but they were too old to reproduce. We thought that the species was functionally extinct. In 1994, surveyors found a reproducing population in Killbuck Creek, Ohio.

 

The purple cat's paw is considered a medium-sized mussel. The males grow to about 2.75 inches in length and the females about half that size. The inside of their shells is purplish to deep purple.
