簡短描述
檢索表 | 型態特徵 | 形態測量圖
背的軟條 (總數) : 8; 臀鰭軟條: 7 - 9. Diagnosis: Distinguished from other cyprinids except Notropis buccatus by having a modified infraorbital and preoperculomandibular canals. It differs from N. buccatus by possessing longer gill rakers (length to width average 2.2, 4.8-2.5 vs. 1.0, 0.8-1.4), absence of breast squamation (vs. with scales), and possessing 5 infraorbital ossicles (vs. 4) (Ref. 57709).
鑑別: 藉由有一個除了 頰美洲鱥〔Notropis buccatus〕 以外與其他的鯉魚區分了變異的眶下與前鰓顎管。 它藉由持有較長的鰓耙 (對寬度平均 2.2, 4.8-2.5 的長度 vs.1.0,0.8-1.4) 有別於 N. buccatus, 缺乏胸部鱗片的排列 (vs. 有鱗片), 而且持有 5個眶下的小骨 (vs.4).(參考文獻 57709)
The species occurs in small schools, often in clear, shallow (up to 50 cm) streams in slow to moderate runs; prefers sandy to sand mixed with gravel substrates (Ref. 57709).
此魚種出現形成小群魚群, 常見於緩慢到中等的小支流的清澈又水淺的 (向上到 50 公分) 溪流中; 偏愛沙的對混和著礫石底部的沙子.(參考文獻 57709)
