Leopard darter [Percina pantherina]
The leopard darter is approximately 3 inches long. This fish has dark eyes, a white belly, and a light olive back that is spotted with dark spots and saddles. This fish feeds on algae and small invertibrates and in riffles and shallow pools of fast flowing streams from mountainous or hilly terrains with rubble, boulder or bedrock bottoms. This fish is only found in the Little River basin in southeastern Oklahoma and in southwestern Arkansas.
Leopard darter habitat has been significantly altered by dam and reservoir construction on the Little River system. In addition, agricultural and industrial practices have been known to influence water quality essential for darter survival. The Fish and Wildlife Service (FWS) has designated protection ranges in the Little River in both Oklahoma and Arkansas, the Black Fork Creek, Glover Creek, including portions of east and west forks, and the main channel of the Mountain Fork Creek. Survival of this species depends on efforts to improve water quality and to protect and restore leopard darter habitat.
