Environment: milieu / climate zone / depth range / distribution range
生态学
; 淡水 底中水层性. 温带; 37°N - 34°N
North America: upper Green River drainage in Kentucky and Tennessee, USA; 1 record from Roaring River (Cumberland River drainage) in Tennessee (Ref. 86798). Individuals from the Duck River originally allocated to N. elegans are N. fasciatus, the latter restricted to the Duck River system and two minor tributaries of the lower arm of the Tennessee River, Tennessee (Ref. 56218).
北美洲: 在肯塔基州与美国田纳西州局限于绿色的河流域了。 (参考文献 5723) 本来分派到 N. elegans 的个体从鸭子河是 N. fasciatus, 后者局限于鸭子河流域与田纳西河,田纳西州的下面手臂的二个较小支流了。 (参考文献 56218)
