Short description Morphology | Morphometrics

Dorsal spines (total): 14 - 15; Dorsal soft rays (total): 8-10; Anal spines: 1; Anal soft rays: 16 - 17. Diagnosis: Dorsal fins III + XI-XIII + 8-10 (usually III + XII + 9); anal fin I, 16-17 (usually 16 rays); pectoral fin 15: 2-3 + 5-6 + 7 (usually 2+6+7).

Dentary pores 3 + 2 + 3 ; head 3.3-3.9 in SL; eye 2.8-3.6 in head length; orbital margin serrated finely; orbital cirrus minute, about half the diameter of pupil, may be rounded or divided; supratemporal sensory canal crescent-shaped; first dorsal fin about equal in height to second in females, higher in males. Key features are: Body stripes 4-5 diagonal dark brown, dorsal and caudal fins reddish, caudal peduncle with dark bar (Ref. 5497, 57774, 88983).

Biology     Glossary (e.g. epibenthic)

This species is uncommon (Ref. 57774) and very secretive. Adults live in sheltered lagoons with many nooks and crannies, in close association with hard corals (Ref. 88983). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).

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=0.00550 (0.00251 - 0.01205), b=3.08 (2.89 - 3.27), 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) .
