Identification keys | Morphology | Morphometrics
Dorsal spines (total): 7; Dorsal soft rays (total): 12; Anal spines: 1; Anal soft rays: 12. This species is distinguished by the following characters: D VI + I,12; A I,12; pectoral rays 17; cycloid scales, partially to complete embedded, nonimbricate, not in regular rows, about 120-125 in longitudinal series; naked head; elongated body, the depth at anal-fin origin 7.75-7.9 in SL, compressed; head length 3.55-3.6 in SL; eye extending little above dorsal profile of head; orbit diameter 4.35-4.45 in head length; gill opening reaching forward to below rear margin of preopercle; the first dorsal spine is longest, 3.0-3.15 in SL, twice length of longest dorsal soft ray; caudal fin slightly pointed, longer than head length; pelvic fins are fully united, nearly reaching anus, 3.45-3.5 in SL, with well developed frenum; colouration when fresh - pale grey with a series of 14 dark brown bars on body, much wider than pale interspaces and broken into one or two spots dorsally; head with irregular, close-set, dark brown spots of variable size, generally smaller anteriorly; first dorsal fin with close-set, dark brown spots, are larger posteriorly; third membrane of the first dorsal fin with a curved white mark on a large black spot near margin; second dorsal fin is whitish with a blackish margin, a middle dark brown stripe, and a row of large, dark brown, bilobed spots along its base; dorsal part of caudal fin with an oblique, blackish-edged, bluish white band (Ref. 88846).
Lives symbiotically in sand near fringing reef with an unidentified alpheid shrimp, in shallow waters. Collected b multi-pronged spears (Ref. 88846),

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.

Trophic level (Ref.
69278): 3.3 ±0.3 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.
