Unique Characters: Black stripe on side, anterior to eye, but not on snout. Caudal spot disconnected from lateral stripe. Pointed snout and horizontal mouth. Anal fin base heavily pigmented. Usually 7 anal fin rays. Usually unscaled breast. Complete lateral line. Dash (smudge) of black pigment at base of dorsal fin. Very white sides below lateral line and venter; melanophores absent along the sides and above the anal fin. In life, it has two light dashes along the back before and after dorsal fin. Straw yellow-colored during spawning season. The population(s) in the lower Catawba appear “different” from their eastern counterparts in terms of overall body color and physical appearance. In some respects they appear to resemble Sand Shiner, Notropis stramineus.
