SPECIES DESCRIPTION

This freshwater mussel is moderate to thin shelled, elongate to quadrate in shape with a size of approximately 6 inches. The interior color is white to iridescent and external color ranges from tan to black with indistinct broad green rays. The shell is covered by small ridges. The species is an obligate riverine species preferring clear water riffles with moderate current on substrate of medium to small sized gravel. Historically occurred in the Fall, Elk, Verdigris, Cottonwood, Spring and Marais des Cygnes Rivers. It still occurs in the same watersheds, but at greatly reduced numbers and distribution.

SPECIES PROTECTION AND CRITICAL HABITATS:
