Short description Morphology | Morphometrics

Dorsal spines (total): 2; Dorsal soft rays (total): 5-7; Anal spines: 0. Diagnosis: adipose fin rayed in adults, 1st ray forming a spine (not visible in juveniles); adipose-fin rays becoming visible at sizes of 90-100 mm SL, and the spine at 200 mm; dentition very well developed: premaxillary tooth plate broad (38-45% of head length), palatine dentition consisting of an elongate vomerine plate and of a dermo-palatine plate in young individuals (60-70 mm SL); palatine tooth plates narrow and long with much weaker dentition; nasal barbel long, reaching at least to anterior part of orbit; maxillary barbel very long, exceeding at least the anterior part of dorsal fin and often reaching to adipose fin; caudal-fin lobes marked by a dark band; cranial bones well developed; length of occipital process usually less than 1.4 times its width (Ref. 57126).

Biology     Glossary (e.g. epibenthic)

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.7500   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01445 (0.00786 - 0.02658), b=3.04 (2.88 - 3.20), in cm total length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±0.43 se; based on food items.
Resilience (Ref. 120179):  Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  High vulnerability (59 of 100).
Price category (Ref. 80766):   Unknown.
