Peppered chub
The peppered chub, also known as the Arkansas River speckled chub, is a species of freshwater ray-finned fish belonging to the family Leuciscidae, the shiners, daces and minnows. It historically occurred throughout the Arkansas River drainage, but today is found in the Ninnescah River, a small portion of the Arkansas River in Kansas and the South [Canadian River] between Ute and Meredith reservoirs in New Mexico and Texas. Its preferred habitat is shallow channels of large, permanently flowing, sandy streams, and prefers currents over a substrate of clean, fine sand.
