Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 12; Dorsal soft rays (total): 13; Anal spines: 4; Anal soft rays: 10. This species is distinguished by the following characters: scales above lateral line to mid-base of spinous portion of dorsal fin 3 1/2; half-scale not present anterior to first lateral-line scale; head dorsal profile nearly uniformly convex; anterior end of each nasal bone has a sharp, forwardly directed spine; with a strong spine at corner of preopercle, significantly larger than other serrations; pectoral-fin rays 17; lateral-line scales 29; gill rakers 8 + 13; the last dorsal-fin spine is shorter than penultimate spine; body depth 2.2 in SL; HL 2.4 in SL; very short snout, 6.6 in HL; least depth of caudal peduncle 4.9 in HL. Colour when fresh: silvery head and body, re dorsally with upper sides of body red with silver spots; red eye with black pupil; rose coloured vertical fins and caudal fin; translucent fins (Ref. 121787).

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=0.01778 (0.00696 - 0.04547), b=3.02 (2.79 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 3.4 ±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.
