Description synthétique Clés d'identification | Morphologie | Morphométrie

Épines dorsales (Total) : 3; Rayons mous dorsaux (Total) : 24 - 25; Épines anales: 3; Rayons mous anaux: 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).

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=0.00501 (0.00193 - 0.01299), b=3.10 (2.88 - 3.32), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.3 ±0.5 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
