Description synthétique Clés d'identification | Morphologie | Morphométrie

Vertèbres: 128 - 142. Adults pale with small black spots on face; black spots proportionally much larger in young (Ref. 30404).

Occurs in lagoons, reef flats and seaward reefs (Ref. 1602, 48635). Prefers protected inshore waters among dead corals, common in harbors and small caves (Ref. 30404). Probably nocturnal (Ref. 1602). Feeds on fishes and crustaceans (Ref. 9710). Possibly a protogynous hermaphrodite (Ref. 32169). Current age of a captive individual is 18 years, which exceeds 100 cm and approximately 10 lbs (owner Mark Palermo, pers. comm. 07/12). Minimum depth reported taken from Ref. 86942.

Estimates based on models

Preferred temperature (Ref. 115969): 24.9 - 29, mean 28 (based on 774 cells).

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

Bayesian length-weight: a=0.00040 (0.00027 - 0.00059), b=3.31 (3.20 - 3.42), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 4.0 ±0.67 se; based on food items.

Résilience (Ref. 120179): Faible, temps minimum de doublement de population : 4,5 à 14 années (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): High vulnerability (57 of 100).
