Morphology | Morphometrics
(total): 1. Diagnosis: adipose fin present and fully developed; inner side of pectoral fin spine weakly serrated; barbels well developed, nasal barbel at least reaching to posterior border of eye but never reaching beyond anterior border of opercle; posterior nostrils closer to each other than the anterior nostrils; medium-sized species, growing over 25 cm SL with distinct marbling, particularly in specimens smaller than 10 cm SL, larger specimens marbled and sometimes with more or less indistinct longitudinal streaks; head broad, massive and rectangular (interorbital width 62-74% HL); mouth width 61-78% HL; 39-52 branched anal fin rays; lower jaw reaching as far as upper jaw or slightly beyond snout (Ref. 81643).
Coloration: preserved specimens: body marbled (particularly in juveniles < 10 cm SL); largest individuals marbled and sometimes with lateral bands more or less distinct (Ref. 81643).
Oviparous, eggs are unguarded (Ref. 205).

Phylogenetic diversity index (Ref. 82805
= 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. 93245
Trophic Level (Ref. 69278
): 3.4 ±0.5 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Assuming fec > 10,000).
Vulnerability (Ref. 59153
