Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 8; Anal spines: 1; Anal soft rays: 8. This species is distinguished by the following characters: diagonally slanting grey and yellow bars on body; nape scaled with about 5-6 predorsal scales; pectoral fin with 16-17 unbranched rays; unbranched fifth pelvic-fin ray, about half length of fourth ray; interorbital region with a U-shaped trench and no postorbital trenches (Ref. 112075).
Body shape (shape guide): fusiform / normal; Cross section: oval.

Biology     Glossary (e.g. epibenthic)

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01023 (0.00477 - 0.02194), b=3.01 (2.83 - 3.19), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
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). 🛈
