Short description Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 22-28; Anal spines: 0; Anal soft rays: 36 - 43. Barbel with three branches arising from stem; medial branch stout, bulbous and with distal filaments barely reaching to barbel tip; lateral branches tapering, extending well beyond end of barbel (except in small specimens); terminal bulb unpigmented and elongated, occupying most of distal barbel, tightly constricted distally into spheroidal terminal section; terminal filament or single-based group of filaments arising ventrally from constriction.

Epi- and mesopelagic (Ref. 58302).

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=0.00389 (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): 4.2 ±0.73 se; Based on food items.

Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Low to moderate vulnerability (32 of 100) .
