Descrição breve Chaves de identificação | Morfologia | Morfometria

Espinhos anais: 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).

Biologia     Glossário (ex. 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).

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).
Nível Trófico (Ref. 69278):  2.9   ±0.45 se; based on food items.
Resiliência (Ref. 120179):  Elevada, tempo mínimo de duplicação da população menor que 15 meses (Assuming fec > 10,000).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (21 of 100).
