Description synthétique Clés d'identification | Morphologie | Morphométrie

Épines dorsales (Total) : 8 - 9; Rayons mous dorsaux (Total) : 22 - 33; Épines anales: 2 - 3; Rayons mous anaux: 18 - 31; Vertèbres: 22. Body varying from light bluish grey to dark brown, without blue lines. Outer part of pectoral fins abruptly white, the demarcation curved such that pale area is broadest on central part of fin. Least depth of caudal peduncle 3.1 to 3.3 times in head length. Maximum standard length about 33 cm (Ref 9808).

Found off steep outer-reef escarpments. May be solitary but most commonly seen in small aggregations feeding on zooplankton well off the bottom.

Estimates based on models

Preferred temperature (Ref. 115969): 24.7 - 28.4, mean 26.3 (based on 333 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01413 (0.00613 - 0.03255), b=3.00 (2.79 - 3.21), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.4 ±0.45 se; based on food items.

Résilience (Ref. 120179): Milieu, temps minimum de doublement de population : 1,4 à 4,4 années (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (23 of 100).
