Morphology | Morphometrics
soft rays: 11;
Vertebrae: 26. This species is distinguished by the following characters: body oval, deep and well compressed; mouth terminal, slightly oblique ventrally and the anterior tip o upper jaw bluntly pointed; incisiform teeth; scales on interorbital region; caudal fin emarginate, shallow; D XI,12; A III,11, anterior part of anal-fin soft-rayed portion well elevated; the longest anal-fin soft ray (second) longer than the longest dorsal-fin spine (sixth); gill rakers on lower limb of first arch on the external side 5-6 upper limb, 13-16 lower limb; pectoral fin long and broad, with 18-19 (mode 18) soft rays; pelvic fin when depressed almost reaching the anus (19.3-20.8%SL); total lateral line with 67-78 scale rows, pored scales 54-63; longitudinal row with 64-68 scale rows; vertebrae: precaudal 10, caudal 16; pterygiophores: dorsal 21 and anal 12 (Ref. 95491).
Central Pacific: Hawaiian and probably in the Line Island groups (Ref. 86689).
Benthopelagic in shallow water, in the surge zone near coral and rocky reefs (Ref. 58302).

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01778 (0.00715 - 0.04425), b=3.01 (2.79 - 3.23), based on LWR estimates for this (Sub)family-body shape (Ref. 93245
Resilience (Ref. 69278
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Moderate vulnerability (37 of 100) .
