简单描述 检索表 | 型态特徵 | 形态测量图

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).

生物学特性     字汇 (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).

偏爱较小的森林溪流，底部为岩石的地方。 主要吃陆生与水生昆虫。 (参考文献 7248)

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00589 (0.00263 - 0.01321), b=3.02 (2.83 - 3.21), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
营养阶层 (Ref. 69278):  2.9   ±0.45 se; based on food items.
回复力 (Ref. 120179):  高度, 族群倍增时间少于 15个月 (Assuming fec > 10,000).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (21 of 100).
