Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 3; Dorsal soft rays (total): 24 - 25; Anal spines: 3; Anal soft rays: 12 - 13. This species distinguished by the following characters: 24-25 (usually 24) segmented dorsal-fin rays; 12-13 (usually 13) segmented anal fin rays; 18-25 anterior lateral line scales; 16-20 (usually 20) circumpeduncular scales; relatively stout and pungent anal-fin spines, the second much stouter than the third; color in alcohol consisting of pale central spots on scales of flanks behind pectoral fin base and dark central spots on breast scales (Ref. 81967).

Biology     Glossary (e.g. epibenthic)

Known from coral reefs in harbours and near mangrove areas (Ref. 81967).

Estimates based on models

Preferred temperature (Ref. 123201): 28.4 - 29.3, mean 28.9 °C (based on 597 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00490 (0.00187 - 0.01281), b=3.11 (2.88 - 3.34), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.5 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
