Short description Morphology | Morphometrics

Dorsal spines (total): 1; Anal spines: 0. Diagnosis: gill slits not extending ventrally beyond pectoral-fin insertions; post-orbital length at most 60% of snout length; maxillary barbels unbranched, not fringed or very slightly fringed at base, shorter than head, without tubercles or basilar membrane; mandibular barbels with a long simple and relatively thin ramifications; mandibular teeth numbering 10-16; dorsal-fin spine smooth anteriorly, pectoral-fin spines weakly denticulate; humeral process triangular and rather pointed posteriorly, its upper margin concave; adipose fin poorly developed, distinctly separated from rayed dorsal fin; colour uniform, sometimes with very fine punctuations (Ref. 57223). Coloration: uniformly brownish, with numerous small, rounded spots on sides and adipose fin (this colour corresponds to a stuffed specimen)(Ref. 57223).

Biology     Glossary (e.g. epibenthic)

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=0.01122 (0.00437 - 0.02882), b=2.97 (2.77 - 3.17), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.8   ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Moderate to high vulnerability (53 of 100).
Price category (Ref. 80766):   Unknown.
