Cyprinella camura (Jordan & Meek 1884)

This taxon is one of a several benthopelagic species in the Arkansas River system. Benthopelagic river fish are found near the river bottom, feeding on benthos and zooplankton.The Arkansas River rises near Leadville, Colorado at an elevation of approximately 3010 meters about thirty kilometers north of Mount Elbert, Colorado's highest peak. Tthe upper reaches of the Arkansas River manifest turbulent high gradient passage through rugged volcanic terrain; the flow continues to the Royal Gorge, where one of the world's highest suspension bridges towers 320 meters above the river surface; thereafter, the river course flows generally eastward through Kansas, thence southeastward through Oklahoma and Arkansas until its discharge to the Mississippi River. The river basin also includes parts of the states of New Mexico, Texas and Missouri. Chief tributaries of the Arkansas River are Purgatoire River, Fountain Creek, Pawnee River, Salt Fork River, Illinois River,Verdigris River, Neosho River, Cimarron River and the Canadian River. The mean annual discharge at Little Rock, Arkansas is approximately 1118 cubic meters per second, a level remarkably undifferentiated from virgin flow, before the era of locks, impoundments and extraction. Water quality at the headwaters near Leadville, Colorado is quite high, consisting of cold, rapidly flowing water of pH 6.3. Concentrations of calcium, sodium, magnesium and chloride are all less than ten milligrams per liter in this pristine headwaters area. Crossing the Southern Plains below Great Bend, Kansas, the pH elevates to a level of 8.0, sodium concentrations rise to a range of 300 to 500 mg/l, with other ions rising by similar large percentages. After receiving the more pristine runoff from the Ozark Plateau, below Fort Smith, Arkansas, the pH level can be measured as low as 7.5, and sodium along with other ion concentrations are reduced by a factor of four. At the Mississippi Embayment, nitrate and phosphate levels are elevated due to row crop agricultural runoff of this region. There are 141 species of fish present in the Arkansas basin, including two near endemic benthopelagic species: slough darter (Etheostoma gracile) and speckled darter (Etheostoma stigmae). The federally threatened and near-endemic Neosho madtom (Noturus placidus) occurs in the Neosho River, a tributary that rises in the Flint Hills. Also present in the Neosho River is the endangered Topeka shiner (Notropis topeka). The cardinal shiner (Luxilus cardinalis) is a near-endemic that is now restricted to populations in the Arkansas River and Red River, and disjunctive populations in the Neosho River. In the upper Arkansas River mainstem a number of reptiles are found in the upper basin, including yellow mud turtle (Kinosternon flavescens), midland smooth softshell (Apalone mutica), western spiny softshell turtle (Apalone spinifera hartwegi) and northern water snake (Nerodia sipedon). In the downriver portions of the basin (Eastern Oklahoma and Arkansas) are found the false map turtle (Graptemys pseudogeographica) and the venomous cottonmouth (Agkistrodon piscivorus).

Inhabits sandy and rocky pools and runs of clear to turbid creeks and small to medium rivers (Ref. 5723, 86798).

The bluntface shiner (Cyprinella camura) is a species of fish in the carp family, Cyprinidae. It is native to the United States, where it occurs in two disjunct populations on either side of the Mississippi River. It is a common fish in its range, even abundant in some localities.

The fish reaches a maximum length of about 15 centimeters. It lives in creeks, rivers, and pools.
