Etymology: Leiognathus: Greek, leios = smooth + Greek, gnathos = jaw (Ref. 45335);  robustus: Named for the robust nature and large size of the species when compared to all congeners except L. equulus and L. fasciatus; an adjective..

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 8; Dorsal soft rays (total): 16; Anal spines: 3; Anal soft rays: 14. This species is distinguished from Leiognathus equulus (the only other species of leiognathid known to possess a non-sexually dimorphic light organ system) by the having no occipital hump (vs. pronounced hump); with a mildly sloping predorsal profile (vs. strongly curved, creating the image of an arched back); with frontal and lateral ethmoid ossifications that project anterodorsally and extend well anterior of the orbit to form a distinct preorbital protuberance (vs. slight bulge above orbit); and unexposed nuchal spine in lateral view (vs. exposed and projecting, particularly distally) (Ref. 76780).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5039   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01820 (0.00790 - 0.04194), b=3.01 (2.81 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.0   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (12 of 100).
