簡短描述
檢索表 | 型態特徵 | 形態測量圖
臀鰭軟條: 12 - 17. Body slender; head flat. Adipose fin white or clear; pectoral fin short with 4-5 large sawlike teeth on rear edge; absence or presence of small teeth on front edge; rear edge of caudal fin straight or with slightly rounded corners; adipose and caudal fins broadly joined with tiny notch between. Color geographically variable. There are 2 subspecies: Noturus hildebrandi latus with shorter head and with 4 white or light yellow oval areas on uniform red-brown to black back; is strongly bicolored with brown to black upper side, white or yellow below. Noturus hildebrandi hildebrandi possesses longer head and prominently blotched color pattern above and almost to belly (Ref. 86798).
Inhabits mixed rock and sand riffles and runs of clear lowland creeks and small rivers. Often found near debris (Ref. 5723, 86798). Feeds on midge and caddis larvae, together with mayfly and stonefly nymphs (Ref. 10294).
棲息於混合岩石與有沙的急流與清潔的水流低地小溪與小河。 時常在殘礫的附近發現。 (參考文獻 5723,10294) 吃蚊與石蠶仔魚, 伴隨著孚游類與 stonefly 蛹.(參考文獻 10294)
