Short description Identification keys | Morphology | Morphometrics

Dorsal soft rays (total): 25; Anal soft rays: 38; Vertebrae: 68. A single terminal bulb 1.1-1.2% SL. Barbel length 48-49% SL at 11.2-14.8 cm; 32-37% at 19.4-21.4 cm. Short, slender terminal filaments 3, each branching complexly and with numerous small bulblets forming swellings. Axis of stem well pigmented proximally, becoming sparsely pigmented distally; a dark spot usually at the base of distal bulb. No external pigment spots proximal to bulb. External chevron-shaped or roundish striated areas unpigmented. Middorsal paired spots between occiput and dorsal-fin origin 7 (Ref. 11333).

Estimates based on models

Preferred temperature (Ref. 123201): 14 - 24.8, mean 21.1 °C (based on 38 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00302 (0.00116 - 0.00786), b=3.12 (2.89 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.3 ±0.8 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming tmax>3).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
