Identification keys | Morphology | Morphometrics
Dorsal spines (total): 6 - 7; Dorsal soft rays (total): 9 - 10; Anal spines: 1; Anal soft rays: 8; Vertebrae: 28. Diagnosis: Preoperculum without a spine, but with small flat projection adjacent to lower preopercular pore; mental fraenum low with short lateral lobes; mouth small; reaching to below anterior margin of eyes; jaws forming an angle of 40–50° with body axis; upper margin of upper jaw in line with lower margin of pupil; head robust and large, cheeks slightly bulbose and tapering; interorbital narrow, less than eye length; predorsal area scaled forward to just behind eye, with a narrow naked patch between and behind eyes; cheek naked; operculum naked; pectoral base with 1–3 vertical rows of scales; prepelvic area about 3/4 scaled in 7–8 rows, naked anteriorly; belly largely scaled, with a very small naked patch behind pelvic insertion; 1st dorsal fin spine 3–5 extending beyond other spines when fin depressed; 1st dorsal fin with black spot posteriorly on membrane surrounding 6th dorsal spine, spot faint in female; pelvic fin thin, length much greater than width, reaching anus; 2nd dorsal rays I,9–10; anal rays I,8; pectoral rays 17–18; longitudinal scale count 30–31; predorsal scale count 15–18; transverse scale count (TRB) 9.5–10.5; gill rakers on outer face of 1st arch 1+1+6–8=8–10; lower gill rakers on outer face of 2nd arch 6–7; branched caudal rays 14–15; vertebrae 12+16=28; papillae, Line 1 (before nasal pore) composed of 2 rows of papillae (sometimes incomplete); line 2 (between nasal pores) composed of a single row of papillae usually continuous across snout; line 5 (suborbital) composed of single row of papillae (double in 1 specimens on 1 side of head below infraorbital pore), joining line 7 below posterior nostril; line 6 (suborbital branch) absent; lines 7, 9, 10 (LL cheek rows) composed of a single row of papillae, but irregular anteriorly appearing double, reaching to posterior preopercular margin; lines 8 and 11 (LT row) reaching just short of posterior preopercular margin; line 12 (outer POP–mandibular) composed of single row of papillae, appearing double along lips, without gap at end of lips; line 13 (inner POP–mandibular)
composed of 2–3 rows of papillae; line 20 (opercular VT row) composed of single row of papillae dorsally, and double ventrally; line 21 (upper opercular OT) composed of single row of papillae, strongly curved ventrally meeting or almost meeting line 22; line 22 (lower opercular OT) composed of single row of papillae, curving upward along posterior opercular margin; several vertical papillae rows on belly; a single curved line anteriorly on most body scales (often obscure dorsally and posteriorly); chin with an oval patch of papillae behind mental fraenum, with a notch posteromedially without papillae (Ref. 103536).

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=0.00708 (0.00333 - 0.01504), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.5 ±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).
