Morphology | Morphometrics
Diagnosis: Body oval, deep and well compressed. Mouth terminal, slightly oblique ventrally and the anterior tip o upper jaw bluntly pointed. 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 23-25 (mode 24). Pectoral fin long and broad, with 18-19 (mode 18) soft rays. Pelvic fin when depressed almost reaching the anus (Ref. 55727).
Central Pacific: Hawaiian and Line Island groups.

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01778 (0.00708 - 0.04465), b=3.01 (2.79 - 3.23), based on LWR estimates for this Subfamily-body shape (Ref. 93245
Resilience (Ref. 69278
): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (21 of 100) .
