簡短描述 型態特徵 | 形態測量圖

臀棘 0. Diagnosis: adipose fin always present; anterior nostrils closer to each other or at same distance as posterior ones; barbels well developed, nasal barbel at least reaching to anterior border of opercle; snout reaching beyond lower jaw, upper lips slightly surrounding lower jaw when mouth is closed; inner side of pectoral spine feebly serrated; striking brownish colour pattern, often irregularly marbled and characterized by the presence of a very dark blotch above pectoral spine, where swim-bladder lies close below skin; eyes rather small (Ref. 43912).

生物學特性     字彙 (例如 epibenthic)

Prefer smaller forest streams with rocky (Ref. 7248, 43912) or sandy bottom (Ref. 43912). Nocturnal (Ref. 43912). Probably carnivorous (Ref. 43912), with a preference for terrestrial and aquatic insects (Ref. 7248, 43912). Oviparous, eggs are unguarded (Ref. 205).
