簡短描述
檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 11 - 13; 背的軟條 (總數) : 11 - 15; 臀鰭軟條: 11 - 13. Distinguished from populations of Crystallaria asprella of the Gulf Coast, Mississippi River and Wabash River by a combination of the following features: gape width larger approximately equal to or exceeding the inter-pelvic fin base width; a preorbital blotch distinctly separate from the anterior orbital rim; pelvic fins distinctly falcate in both sexes; cheek scale rows reduced (modally 2); opercle scale rows reduced (modally 2); number of midlateral blotches higher (modally 13); number of anal-fin rays lower (modally 13); number of dorsal-fin spines lower (modally 12); and scales below the lateral line higher (modally 11) (Ref. 74948).
Found mostly in waters with moderate flows over a sand, gravel and cobble mix of benthic substrate within the lower sections of riffles or upper parts of pools (Ref. 75199).
