Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 11; Rückenflossenweichstrahlen (insgesamt) : 12; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 8. Snout profile low, sloping very gently. Preorbital bone narrow, its width less than half of eye diameter. Preopercular notch and knob poorly developed. Scale rows on back rising obliquely above lateral line. Generally dark brown of the upper part of the head and body with a broad white horizontal band immediately below. The lower part of the head and body dusky brown with a suffusion of yellow. A pair of white spots is on the back just below the dorsal fin base (Ref. 469).

Adults inhabit coral reefs (Ref. 9710, 48635) and outer reef slopes (Ref. 37816, 48635). They sometimes form large schools of more than 100 individuals. Often solitary (Ref. 48635). Feed mainly on small fishes and crustaceans. Generally uncommon (Ref. 9710).

Estimates based on models

Preferred temperature (Ref. 115969): 27.5 - 29.2, mean 28.6 (based on 602 cells).

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

Bayesian length-weight: a=0.01479 (0.00706 - 0.03101), b=2.97 (2.81 - 3.13), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 4.0 ±0.65 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): hoch, Verdopplung der Population dauert weniger als 15 Monate. (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (15 of 100).

Preiskategorie (Ref. 80766): High.
