Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 10; Dorsal soft rays (total): 9 - 10; Anal spines: 3; Anal soft rays: 7 - 8. This species is distinguished from its congeners by the following set of characters: absence of paired spines on chin; proximal-middle radial of FAP curved, with cone-shaped hollow divided by lamellar septum; hollow shallow, its lower part of the hollow terminates at the midway between the upper part and the base of the first anal-spine; lateral wing well developed, extending from the upper part of hollow to the base of the anal-spine; anterior surface roundly convex; vane long, extending from the level of lateral wing to the base of anal-spine; membranous edge of opercle winth a prominent triangular tip; pectoral-fi tip not reaching the vertical level of anus; and lateral-line scales 53-56 (Ref. 138192)
Body shape (shape guide): elongated; Cross section: compressed.

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=0.01148 (0.00472 - 0.02793), b=3.03 (2.82 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.5 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100). 🛈
