The beak sculpture consists of numerous wavy ridges and the cavity is very deep. They have very heavy, well developed cardinal teeth and lateral teeth along the hinge. The thick and heavy shell is yellowish brown or green brown, becoming dark brown in older individuals.

In most cases, at least one specimen record exists for each listed natural community. For certain taxa, especially poorly collected or extirpated species of prairie and savanna habitats, natural community lists were derived from inferences from collection sites and habitat preferences in immediately adjacent states (particularly Indiana and Illinois). Natural communities are not listed for those species documented only from altered or ruderal habitats in Michigan, especially for taxa that occur in a variety of habitats outside of the state.</p> <p>Natural communities are not listed in order of frequency of occurrence, but are rather derived from the full set of natural communities, organized by Ecological Group. In many cases, the general habitat descriptions should provide greater clarity and direction to the surveyor. In future versions of the Rare Species Explorer, we hope to incorporate natural community fidelity ranks for each taxon.</p> </div> </div> <div class="description"> <h2 class="section">Management Recommendations</h2> <p>Like other mussels, threats are varied and include: habitat degradation, poor water quality, flow alterations, water temperature changes, heavy metals, organic pollution, sedimentation, and siltation. Maintenance or establishment of vegetated riparian buffers can help protect mussel habitats from many of these threats. Control of zebra mussels is critical to preserving native mussels. As with all mussels, fish host requirements also need to be considered.</p> </div> <div id="survey-methods" class="description"> <h2 class="section">Survey Methods</h2> <h3>Glass-bottom bucket less than waist deep water</h3> <p>Survey Period: From first week of June to first week of October</p> <h3>SCUBA searches</h3> <p>Survey Period: From first week of June to first week of October</p> <h3>Snorkeling searches</h3> <p>Survey Period: From first week of June to first week of October</p> </div> <div id="references" class="description"> <h2 class="section">References</h2> <h3>Survey References</h3> <ul> <li>Cummings, K.S. and C.A.
