Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 18 - 19; Dorsal soft rays (total): 10 - 11. Depth of body 2.2-2.5 times in SL; head length 3.1-3.4 times in SL (Ref. 47113). Eye diameter 3.0-3.1 times in HL; interorbital width 3.4-3.8 times in HL; premaxillary pedicel 2.5-3.0 times in HL and depth of preorbital 5.7-6.4 times in HL (Ref. 47113).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

The spawning site or nest is normally constructed under and against a rock with a diameter of between 50 to 200 cm; the male excavates the sand from beneath the rock and heaps it up, building a semicircular wall around the spawning site; male spawning sites are usually at least 4 meters apart (Ref. 47113).

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=0.01514 (0.00700 - 0.03275), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.4   ±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 (10 of 100).
