Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 5 - 7; Dorsal soft rays (total): 8 - 9; Anal spines: 1; Anal soft rays: 10 - 12; Vertebrae: 38 - 43. This species is distinguished by the following set of characters: premaxillary ascending process long and slender, widest point at the distal half; maxilla curved downward posteriorly with a rounded posterodorsal edge; anus located slightly anterior to appressed tip of pelvic fin (holotype and 35 paratypes) or just at the appressed tip (12 paratypes) (distance between pelvic-fin insertion and anus ca. four-fifths of pelvic-fin length or longer); with a distinct black crescent marking in front of eye in preserved specimens; eye large with diameter 9.5-11.9 % SL or 36-44 % HL; interorbital somewhat wide, width 9.8-11.8 % SL or 36-43 % HL; posterior margin of lateral and predorsal scales entire; no distinct projection on posterior margin of axillary scale (Ref. 92894).
Body shape (shape guide): elongated; Cross section: compressed.
Usually found along the open coast or sometimes in the inner parts of bays (Ref. 92894).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00562 (0.00240 - 0.01320), b=3.15 (2.95 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 3.3 ±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.
