Morphology | Morphometrics
Semotilus lumbee is similar to S. atromaculatus, but lacks discrete black spot at dorsal fin base (dusky spot may be present), more strongly bicolored (dark above, white below), has 9 rays on dorsal fin, larger scales (usually 18 scales around caudal). This species possesses 42-52 lateral line scales. Breeding males have red fins (Ref. 86798).
Occurs in flowing, sand-bottomed and gravel-bottomed pools and runs of headwaters, creeks, and small rivers (Ref. 5723).
