Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 8; Dorsal soft rays (total): 9; Anal spines: 2; Anal soft rays: 8; Vertebrae: 24. Generally smooth to crenulate preopercle edge, one predorsal scale, 13 well-developed gill rakers on first arch, fourth dorsal spine the longest, and a single dark spot, perhaps appearing as an ocellus in life, on the body just behind the opercle flap.

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±0.6 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).
