Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 9; Dorsal soft rays (total): 12; Anal spines: 3; Anal soft rays: 11 - 13. This species can be distinguished from other congeners in having a broad band of small scale rows on the cheek; with a single small scale below the eye; the first two dorsal-fin spines are short, their length similar to those of other spines of dorsal fin; central gill-raker of lower limb of first gill arch with a single branch; greate body depth 33.5-39.2% SL; several small blotches on the anal-fin base; scale rows below lateral line 10; first upper limb of gill arch with four branches on central gill-raker; head length 32.9-36.0% (mean 34.3%); pre-pectoral-fin length 29.8-32.5% (31.2%); orbit diameter 6.1-7.3% (6.8%); postorbital length 14.9-18.4% (16.8%); small blotches on head (Ref. 127939).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = No PD50 data [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01995 (0.00906 - 0.04395), b=3.01 (2.83 - 3.19), in cm total length, based on all LWR estimates for this body shape (Ref.

Trophic level (Ref.
69278): 3.5 ±0.5 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.
