Short description Morfología | Morfometría

Espinas dorsales (total): 1; Espinas anales 0. Diagnosis: gill slits not extending ventrally beyond pectoral-fin insertions; post-orbital length at least 60% of snout length; maxillary barbels unbranched, longer than head, without tubercles and bordered by a black basal membrane; outer mandibular barbels with short and simple ramifications; branches of inner mandibular barbels subdivided/dichotomous but not tuberculate; mandibular teeth numbering 49-82 (64 in the lectotype); denticulations of pectoral-fin spines stronger on inner than on outer margin; dorsal-fin spine smooth anteriorly; only first branched dorsal-fin ray prolonged into a filament; humeral process triangular and granulose, deep, not keeled ventrally; adipose fin normally developed, truncate posteriorly and distinctly separated from rayed dorsal fin; eyes large (Ref. 57223). Coloration: body entirely brownish (including ventral areas); numerous small black spots, particularly on head, but sometimes also on sides and fins (Ref. 57223).

Bayesian length-weight: a=0.00933 (0.00303 - 0.02871), b=3.05 (2.80 - 3.30), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nivel trófico (Ref. 69278):  2.5   ±0.31 se; based on food items.
Resiliencia (Ref. 120179):  Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (17 of 100).
Price category (Ref. 80766):   Unknown.
