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 most 60% of snout length; maxillary barbels broadly fringed, shorter than head, unbranched and without tubercles, but with a well visible, broad basal membrane; mandibular barbels with rather numerous, long, simple and tuberculate ramifications; mandibular teeth very long, numbering 6-10 (10 in the lectotype); denticulations on pectoral-fin spines finer and more close-set on outer than on inner margin; dorsal-fin spine finely denticulate on anterior margin; humeral process deep, granulose, its lower margin convex, ending in a blunt point and not keeled; adipose fin normally developed and distinctly separated from rayed dorsal fin, its posterior margin truncate; caudal fin strongly developed as compared to that of other species (Ref. 57223).
Coloration: general appearance greyish, ventral regions lighter; outer margins of caudal fin black-edged (Ref. 57223).
Oviparous (Ref. 205). Maximum reported size: 400mm TL, 310mm SL (Ref. 57223).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01862 (0.01079 - 0.03215), b=2.84 (2.70 - 2.98), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Nivel trófico (Ref.
69278): 2.8 ±0.3 se; based on size and trophs of closest relatives
Resiliencia (Ref.
120179): Medio, población duplicada en un tiempo mínimo de 1.4-4.4 años (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (34 of 100).
