Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 7; Dorsal soft rays (total): 8; Anal spines: 1; Anal soft rays: 8. This species is distinguished by the following set of characters: D VI + I,7- 8, the second and third spines are the longest, with short filamentous tips reaching to between bases of first two segmented rays of second dorsal fin when adpressed; A I,8; pectoral rays 16, all are unbranched; pelvic fin I,5 with the fifth pelvic ray unbranched, 48-55% length of fourth pelvic ray; bony interorbital 53-65% pupil diameter; nape fully scaled with 12-13 scales on midline of predorsal; cheek and opercle covered with scales; scales ctenoid on breast (prepelvic); a prominent dark bar at caudal-fin base and scale pockets are strongly outlined with melanophores (Ref. 100512).
Found in caves and ledges in 107 m depth at the baseof a steep outer reef slope (Ref. 100512).

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).
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).
