Short description Morfología | Morfometría

Espinas anales 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).

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).

Nivel trófico (Ref. 69278): 2.9 ±0.45 se; based on food items.

Resiliencia (Ref. 120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Assuming fec > 10,000).

Fishing Vulnerability (Ref. 59153): Low vulnerability (21 of 100).

Price category (Ref. 80766): Unknown.
