Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 2 - 3; Dorsal soft rays (total): 10 - 12; Anal spines: 1; Anal soft rays: 8 - 10; Vertebrae: 28 - 29. The species has a spinulated posterior and lower margins of praeoperculum, posterior margin of the praeoperculum is usualy unspinulated or in a small number of fish there can be one spinule; insertion of ventral fins is in front of the vertical of the posterior margin of pectoral fin insertion; upper jaw in most fish does not reach the vertical of the posterior eye margin; usually 3 (seldom 2) spiny and 10–12 soft rays in dorsal fin; 8–10 soft rays in anal fin; 23–25 rakers at the first branchial arch; vertebrae 28–29; and pyloric caeca 4–6.

Specimens seined with unclosing fishing gear (Ref. 84090).

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=0.01096 (0.00451 - 0.02668), b=3.10 (2.89 - 3.31), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.2 ±0.3 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
