Short description Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 9-10; Anal spines: 1; Anal soft rays: 8 - 9. Pectoral fin rays simple; spinous dorsal fin elongate or filamentous in both sexes, first to third (rarely fourth) longest; fifth pelvic fin ray well developed, five-tenths to nine-tenths length of fourth ray; cephalic sensory pore system lacking IT and PITO pores, and AITO pore single (except double in smallest paratype) and very large; posterior rays of second dorsal and anal fins elongate, forming a lanceolate shape; membranes of dorsal and anal fins slightly dusky; lower portion of caudal peduncle dusky and pair of vertically elongate black spots at upper and lower caudal fin base, their upper and lower edges often joined or nearly joined at middle of caudal peduncle, especially in mature adults (Ref. 44113).

Found in sheltered reef slopes (Ref. 44113). Forms aggregations of 10-20 individuals among branching coral (Ref. 44113).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00589 (0.00270 - 0.01286), b=3.10 (2.92 - 3.28), based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.1 ±0.3 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 vulnerability (10 of 100) .
