- Comments:
The Ouachita kidneyshell is an Ozarkian mussel that only occurs in a small portion
of four states: Kansas, Oklahoma, Arkansas and Missouri. The shell is flattened, heavy for
its size and kidney-shaped. The greenish-yellow external shell typically has several
distinct fine-lined green rays radiating outward from the umbo. It can be mistaken for the
spike mussel, especially where the two co-exist. See pages 8-9 for a detailed account of
Ouachita Kidneyshell reproduction. This mussel is mainly found in riffles and shallow runs
within the Fall, Verdigris and Spring rivers. Relic shells only are found in the Neosho
River.

orangethroat darter and greenside darter
