Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 1; Mjukstrålar i ryggfenan (totalt) : 5. Diagnosis: labial disk moderately developed and rounded, with thick papillae covering almost its entire surface; mandibular barbels short; auxiliary barbels absent; premaxillary teeth large, arranged in 4-5 rows; only known specimen has 7+6 mandibular teeth, but typical number for this species is probably 7+7; adipose fin short, beginning slightly ahead of anal-fin origin; caudal fin weakly forked, lower lobe longer than upper; eyes not very well developed; dorsal surface of head with longitudinal epidermic ridges forming vermiculations (Ref. 57223).
Coloration: body covered with numerous small dark spots, more or less uniformly distributed on dorsal surface (colour hardly visible on preserved holotype)(Ref. 57223).

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref.

Trofisk nivå (Ref.
69278): 3.1 ±0.4 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 (10 of 100).
