Morphology | Morphometrics
soft rays: 38;
Vertebrae: 66. Two terminal bulbs separated by a long interspace, 2-3 times length of distal bulb. Barbel length increasing with size from 43-60% SL. Relatively long filaments 4, arising together from distal end of distal bulb or from a short stem, with long inclusions as well as rounded bulblets. Distal bulb equal in length to proximal-bulb. Axis of stem with some pigment, but light or unpigmented before proximal bulb; between bulbs pigment noticeably darker at base of distal bulb, forming a spot or small cap. External chevron-shaped or roundish striated areas pigmented or not. Middorsal paired spots between occiput and dorsal-fin origin 8 or 9 (Ref. 11333).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [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), based on all LWR estimates for this body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.0 ±0.7 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (15 of 100) .
