簡短描述 型態特徵 | 形態測量圖

背棘 (總數): 7; 背的軟條 (總數): 8; 臀棘 1; 臀鰭軟條: 8; 脊椎骨: 26. This species is distinguished from its congeners by the following set of characters: D2 I,8; A I,8; pectoral-fin rays fin rays 36-40 (modally 19); longitudinal scale rows 32-35; transverse scale rows 9-10; predorsal scales 11-13 with a trifurcate anterior margin of which point 3 lies above the upper gill opening; vertebrae 10 + 16 = 26; gill opening extending ventrally to the vertical midline of the opercle. Coloration of males and females: males' basal region of body scale pockets with a bright orange spot, somewhat indistinct in females; the lateral side of females with a middle longitudinal row of discontinuous brownish black spots or bars and their dorsal lateral region with 3-4 longitudinal rows of black spots and the caudal fin base with 2 separate, vertical black bars; males with second dorsal fin with 4 longitudinal rows of reddish brown bars or spots and caudal fin with 8-10 waving vertical orange to brown stripes; pectoral fin base with a basal distinct, oblique deep brown stripe; cheek scattered with 16-25 small, orange red spots, brighter in males; the pectoral fin base of the species with a basal distinct, oblique deep brown stripe, followed by a parallel shorter, lighter stripe or waving mark (Ref. 104792).

生物學特性     字彙 (例如 epibenthic)

Adults inhabit lakes and rivers. Juveniles move into the sea and return to rivers after several months. This species has several types differentiated according to shape, coloration, and life history. Each type is isolated by habitat in the same stream.

棲息於湖與河。 稚魚移進海洋中而且好幾個月之後回到河川。 這種有好幾個類型依據區別形狀,顏色與生活歷史。 每個類型被在同一條溪流中的棲息地隔離。
