Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 10 - 14; Dorsal soft rays (total): 10 - 13; Anal spines: 2; Anal soft rays: 8 - 11. This breeding male of this species (under the subgenus Doration) is distinguished by the following characters: a spinous dorsal fin with blue marginal and submedial bands, orange medial band, basal band with bright orange pigment; the soft dorsal, caudal, and pectoral fins have distinct bright orange spots on rays; soft dorsal and anal fins with blue in base of fin; anal fin sometimes with orange spots or streaks on rays; the face and lower head tangerine orange with blue on operculum, preoperculum, cheek, and suborbital bar (but not on lips and mid-gular region); quadrate lateral blue blotches extending ventrad from lateral line scale row; the basicaudal blue bar extending from dorsal to ventral margin of caudal fin; no frenum; incomplete lateral line, unpored scales modally >10 (12); cheek partially scaled; palatine teeth usually absent; present in 29% of specimens; modal counts for D XII-XIII,12, A 9, pectoral fin 15, principal caudal 15, caudal peduncle scales 16, preoperculomandibular canal pores 10; allozyme products of sIdh-A locus are characterized by relative mobilities b, e, and g (Ref. 92294).
Cross section: oval.

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=0.00676 (0.00301 - 0.01516), b=3.12 (2.94 - 3.30), in cm total length, based on LWR estimates for this Genus-body shape (Ref.

Trophic level (Ref.
69278): 3.2 ±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).
