Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 10; Dorsal soft rays (total): 10 - 11; Anal spines: 3; Anal soft rays: 6; Vertebrae: 24. This species is distinguished from its congeners by the following characters: the second to sixth dorsal-fin spines are distinctly long, the eighth and ninth spines distinctly short; pored lateral-line scales 35-36; scale rows between lateral line and the base of sixth dorsal-fin spine 4; lateral side of body with faint black blotches; developed gill rakers 1 (upper limb) + 7-8 (lower limb), total gill
rakers 14-17; cheek scale rows 4-5; preopercular serrae 37-50; interopercular serrae 8-14; subopercular serrae 14-22; posttemporal with a small bony crest with 2-4 serrae; interorbital scales extended to or slightly posterior to the level through the mid orbits; approximately two rows of small scales on the ventral side of the angular, dentary completely naked. Colouration: body and head orange red with four faint blotches on lateral side; the soft portion of dorsal and anal fins with several yellowish stripes; upper tip of caudal fin reddish (Ref. 125677).
Caught as by-catch of bottom-trawl fisheries (Ref. 125677).

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=0.01072 (0.00511 - 0.02246), b=3.06 (2.88 - 3.24), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trophic level (Ref.
69278): 3.4 ±0.5 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).
