Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 9; Rückenflossenweichstrahlen (insgesamt) : 25 - 27; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 24 - 26. Pale brown body; broader, irregular lines on head; orange band between eyes, continued behind each eye to gill cover. Each side of caudal peduncle with single, sharp, forward-pointing erectile spine; spine largely covered by cream sheath; groove surrounded by a black area. Dorsal fin with soft part having longer base than spinous part. Minute scales. Gill rakers 22-26 in anterior row, 23-27 in posterior row. Caudal fin lunate in adults (Ref. 1602).

Schooling species, usually occurring in seaward reefs at depths greater than 9 m (Ref. 1602). Adults mainly on deep coastal reef slopes and outer reef walls, often on deep shipwrecks. Juveniles found on algae-rocky reef (Ref. 48637). Benthopelagic (Ref. 58302). Occur singly or in groups (Ref. 37816). Feed on surface film of fine green and blue-green algae, diatoms, and detritus covering sand (Ref. 1602). Pair-spawner (Ref. 37816). Mainly diurnal. (Ref. 1602). Utilized as a food fish (Ref. 3146).

Estimates based on models

Preferred temperature (Ref. 115969): 20.3 - 28.9, mean 27.2 (based on 2904 cells).

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

Bayesian length-weight: a=0.03020 (0.01872 - 0.04873), b=2.94 (2.80 - 3.08), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.0 ±0.00 se; based on food items.

Widerstandsfähigkeit (Ref. 120179): niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (tmax=28; K=0.29).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (36 of 100).

Preiskategorie (Ref. 80766): Medium.
