Maturity: Lm ?  range ? - ? cm
Max length : 13.7 cm SL male/unsexed; (Ref. 95447)

Short description Morphology | Morphometrics

Dorsal spines (total): 6; Dorsal soft rays (total): 9-10; Anal spines: 3; Anal soft rays: 38 - 45; Vertebrae: 25. This species is distinguished by the following characters: a yellow or yellowish dorsal fin with a black, distal margin along its full length, broadest on anterior rays (pupil-diameter width), gradually narrowing posteriorly, and the last ray with only a black tip; differs from its congeners by having large, deciduous cycloid scales on the flank; pectoral-fin base with a dark, oblong spot; anal fin with a dark margin along its length; 38-45 segmented anal-fin rays; 56-65 lateral-line scales; 31-35 total gill rakers on the first arch (Ref. 95447).

Biology     Glossary (e.g. epibenthic)

Collected with ichthyocide on coral or rocky reefs at depths less than 10 m in areas with ledges, caves, and surge channels (Ref. 95447).

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=0.01585 (0.00666 - 0.03770), b=2.99 (2.78 - 3.20), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.4   ±0.5 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 (25 of 100) .
