簡短描述
檢索表 | 型態特徵 | 形態測量圖
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).
Body shape (shape guide): elongated.
Adults occur in flowing, sand-bottomed and gravel-bottomed pools and runs of headwaters, creeks, and small rivers (Ref. 5723). Migratory behaviour is undetermined (Ref. 126106).
出現於河川源頭,小溪與小的河流動的﹐砂質底的與礫石底水潭與急流。 (參考文獻 5723)
