Short description Morphology | Morphometrics

Dorsal spines (total): 12; Dorsal soft rays (total): 14-16; Anal spines: 2; Anal soft rays: 14 - 15; Vertebrae: 26. Body bluish gray dorsally, the scale edges black to dark brown, shading to orange-yellow ventrally; a small white blotch often present in middle of body just above lateral line; pelvic, anal, and caudal fins bright orange-yellow, the margins black. Remarks: caudal fin slightly emarginate, with broadly rounded lobes.

Adults are found around atolls (Ref. 39312). Life history characteristics for the family specify that this group is oviparous, with distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02239 (0.01068 - 0.04693), b=2.99 (2.81 - 3.17), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.0 ±0.4 se; Based on size and trophs of closest relatives

Resilience (Ref. 69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Low to moderate vulnerability (27 of 100) .
