Short description
Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt): 1; Mjukstrålar i ryggfenan (totalt): 7; Taggstrålar i analfenan 0; Mjukstrålar i analfenan: 11 - 12. Diagnosis: gill slits not extending ventrally beyond pectoral-fin insertions; post-orbital length at least 60% of snout length; maxillary barbels longer than head, unbranched, without tubercles and bordered by a distinct black basal membrane; outer mandibular barbels with numerous short and simple ramifications, branches of inner mandibular barbels short, simple, but thick and sometimes tuberculate; mandibular teeth long, numbering 33-50; dorsal-fin spine and branched dorsal-fin rays prolonged into short filaments, the spine smooth anteriorly; denticulations of pectoral-fin spines finer on outer than on inner margin; humeral process rather slender, granulose, pointed and ventrally keeled; adipose fin well developed and rather close to rayed dorsal fin; colour uniformly dark, without spots on body or fins (Ref. 57223).
Coloration: rather dark, slightly lighter on belly; fins blackish, sometimes faintly spotted (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=0.01622 (0.00874 - 0.03010), b=2.82 (2.66 - 2.98), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref.
93245).
Trofisk nivå (Ref.
69278): 2.9 ±0.3 se; based on size and trophs of closest relatives
Resiliens (Ref.
120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (13 of 100).
