Common name: Western Sand Darter
available through www.itis.gov
Identification: Williams (1975); Becker (1983); Page and Burr (1991) under the name Etheostoma clarum; Etnier and Starnes (1993).
Size: 7.1 cm TL
Native Range: Mississippi River basin from Wisconsin and Minnesota south to Mississippi and Sabine and Neches river drainages, Texas; also in the Green, Cumberland, and Tennessee river drainages (presumably extinct in the first two); generally sporadic and rare (Williams 1975; Page and Burr 1991).

† Populations may not be currently present.
Ecology: Inhabits medium to large streams with moderate current, over sandy areas where it will bury itself leaving only the eyes and mouth visible (Etnier and Starnes 1993).
Means of Introduction: These fish likely gained access to the Wolf system via the Wisconsin-Fox Canal (Becker 1983). Mechanism of transport to West Virginia is unknown.
Status: Established in Wisconsin and West Virginia.
Impact of Introduction: The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.
