Short description Morfologia | Morfometria

Raggi dorsali molli (totale): 5-6; Raggi anali molli: 8 - 10; Vertebre: 32 - 33. Distinguished from all its congeners by possessing tubercles with poorly-demarcated, indistinct margins (versus tubercles with well-demarcated and distinct margins) and the following combination of characters: head width 20.3-25.0% SL; body depth at anus 11.3-14.7% SL; depth of caudal peduncle 5.7-7.3% SL; pectoral-fin length 23.1-28.9% SL; interorbital distance 34-39% HL; eye diameter 7-11% HL; length of nasal barbel 29-65% HL; length of maxillary barbel 122-144% HL; length of outer mandibular barbel 88-134% HL; color pattern of dark-colored patches on a predominantly light-colored body (versus predominantly dark-colored body with light-colored patches in its congeners); and caudal fin strongly forked (Ref. 30226).

Biologia     Glossario (es. epibenthic)

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5001   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.6 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
