SPECIES DESCRIPTION

This freshwater mussel is elongated with a slightly rounded shell. The shell is relatively thin, with a size of approximately 4 inches. There are prominent growth lines. The shell is light brown and has a dull, waxy luster; it usually becomes dark brown with age. Green rays usually cover the surface often chevron shaped during the first three years of growth.
The species is an obligate riverine species preferring shallow clean flowing water in fine to medium gravel substrates. Historically found in the Marais des Cygnes, Cottonwood, Spring, Neosho, Verdigris, Fall and Caney River systems. Currently appears to be extirpated from the Caney River and much reduced in numbers and distribution in the other river systems.
