Short description Morphology | Morphometrics

Dorsal spines (total): 1; Dorsal soft rays (total): 7; Anal spines: 0; Anal soft rays: 12 - 13. Maxillary barbels without basal membrane, reaching to the anterior half of the humeral process and longer than the head; mandibular barbels with short, broad branches (Ref. 81251). Snout subconical; lips moderately developed (Ref. 81251). Premaxillary teeth forming a short but wide band; 22 to 24 movable mandibular teeth (Ref. 81251). Humeral process is twice as long as wide (Ref. 81251). Dorsal spine weakly serrated along the posterior edge but not along the anterior edge; adipose fin as long or only slightly shorter than its distance from the first dorsal fin; pectoral spines are strongly serrated along both edges; pelvic fin not reaching the anal fin (Ref. 81251). Caudal peduncle longer than deep (Ref. 81251). Colour: Body brownish or blackish, marbled with white; fins are whitish marbled with black (Ref. 81251).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01380 (0.00624 - 0.03055), b=2.95 (2.77 - 3.13), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.0   ±0.4 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 (10 of 100) .
