Short description Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 9; Anal spines: 3; Anal soft rays: 5. This species is distinguished by the following characters: A III.5; rigid dorsal-fin spines; relatively long snout with length 18.0-21.2% (mean 19.6%) of SL, and is longer than postorbital length; posterior margin of maxilla just reaching to or short of vertical through the anterior margin of pupil; the distance between tips of lateral lacrimal and first suborbital spines is longer than that between tips of first and second suborbital spines; presence of supplemental preopercular spine; tentacles on supraocular and posterior lacrimal spines are poorly developed, lengths are less than orbit diameter; with few tentacles on trunk and fins; lateral lacrimal and suborbital spines are well developed, with pointed tips; membranes between last spine and fourth soft ray of dorsal fin with a large black blotch (Ref. 106976).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5625   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01259 (0.00606 - 0.02615), b=3.03 (2.86 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.5 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 (10 of 100).
