(North American freshwater catfishes)
Etymology: Noturus: Greek, noton = back + Greek, oura = tail; refred to the position of the tail over the back (Ref. 45335); elegans: elegans meaning elegant, referring to the handsome pigment pattern (Ref. 10294).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Temperate; 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).
