Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Wirbelzahl: 128 - 131. Distinctive black patch mark below eye (Ref. 30404). Body brown, speckled darker; dark anus and gill opening (Ref. 3257).

Inhabits clear seaward reefs of oceanic islands to a depth over 25 m (Ref. 9710). Common on reef walls and steep slopes with holes (Ref. 30404). Inhabits porous coral rock which it shares with swarms of anthiases (Ref. 37816). Feeds on fishes and octopi (Ref. 89972). Territorial and will bite when provoked (Ref. 30404). Minimum depth reported taken from Ref. 9710.

Estimates based on models

Preferred temperature (Ref. 123201): 24.7 - 28.8, mean 27.6 °C (based on 310 cells).

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

Bayesian length-weight: a=0.00047 (0.00025 - 0.00089), b=3.28 (3.13 - 3.43), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.5 ±0.80 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): High vulnerability (60 of 100).

Preiskategorie (Ref. 80766): Medium.

Nutrients (Ref. 124155): Calcium = 27.6 [15.0, 44.0] mg/100g; Iron = 0.466 [0.276, 0.928] mg/100g; Protein = 18.8 [16.6, 21.4] %; Omega3 = 0.104 [0.047, 0.298] g/100g; Selenium = 40.7 [22.0, 81.8] μg/100g; VitaminA = 99.3 [29.0, 315.1] μg/100g; Zinc = 0.759 [0.525, 1.056] mg/100g (wet weight);
