Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 7; Dorsal soft rays (total): 8 - 10; Anal spines: 1; Anal soft rays: 8. This species is distinguished by the following characters: presence of a deep trough in the bony interorbital region about half pupil-diameter in width; with a shallow trough behind the eye along the upper half of the posterodorsal margin of the eye; naked predorsal midline, sides of nape is scaled to just behind the eye; no scales on cheek and opercle; the pelvic fins is connected by a basal membrane reaching to the tips of fifth ray, forming an indented plate; central 4-11 pectoral rays are branched; 5-6 light stripes (orange to red in life) on head and with dark blue interspaces, the body light with distinct scattered oval or round spots (yellowish-orange, orange or reddish in life); the snout is mostly darkly pigmented without distinct stripes in preserved material, but with orange stripes in life; the upper lip largely dark, except posteriorly, usually with orange stripes from the eye obscured by dark pigment on the jaws; uniformly dark lower lip; lower surface of the head with a black curved stripe and with a median black bar connecting to the lower lip; branchiostegal membranes are predominantly light, except for the stripe and the inner margin of the membranes (Ref. 100726).
Common on middle and outer reefs (Ref. 100726).

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=0.00724 (0.00339 - 0.01546), b=3.10 (2.92 - 3.28), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
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).
