Description synthétique Clés d'identification | Morphologie | Morphométrie

Épines dorsales (Total) : 5; Rayons mous dorsaux (Total) : 28 - 29; Épines anales: 2; Rayons mous anaux: 27 - 28. Plain brown or olivaceous in color, paler below; subadults with black caudal rays, narrow margins and white caudal filaments; pectoral fins with white distal margins (Ref. 3145).

Juveniles occur in clear, shallow lagoon reefs at depths as little as 1 m; adults rarely seen in less than 25 m, encountered off outer reef drop-offs in small schools (Ref. 30573, 48637). Benthopelagic (Ref. 58302). Feeds on large zooplankton during the day and shelter within the reef during the night; also benthic algae (Ref. 30573, 48637).

Estimates based on models

Preferred temperature (Ref. 115969): 23.5 - 28.3, mean 27.1 (based on 335 cells).

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

Bayesian length-weight: a=0.02239 (0.01279 - 0.03918), b=2.97 (2.82 - 3.12), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 2.1 ±0.09 se; based on food items.

Résilience (Ref. 120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (K=0.213; Tmax=23).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (45 of 100).

Catégorie de prix (Ref. 80766): Medium.
