Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 13 - 14; Rückenflossenweichstrahlen (insgesamt) : 11 - 12; Afterflossenstacheln: 2; Afterflossenweichstrahlen: 9 - 10. This species is distinguished by the following set of characters: D XIII-XIV,11-12 (usually 12); A II,9-10 (usually 10); pectoral-fin rays 18-20 (usually 19); pelvic-fin rays I,5; caudal-fin rays principal 15, branched 13; procurrent spiniform caudal-fin rays 2; tubed lateral-line scales 16-19 (usually 18-19); gill rakers 7-11 + 18-23, total rakers 26-33 (usually 26-29) (Ref. 125611).

Adults inhabit lagoon and seaward coral and rocky reefs (Ref. 9710). Prefer habitat consisting of boulder substrates or mixed rock, rubble, and sand, at depths between about 3 and 30 m (Ref. 125611). Oviparous, distinct pairing during breeding; eggs demersal and adhere to the substrate, and males guard and aerate the eggs (Ref. 205). Diurnal species (Ref. 54980; 113699).

Estimates based on models

Preferred temperature (Ref. 115969): 18.8 - 28.8, mean 27.2 (based on 636 cells).

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

Bayesian length-weight: a=0.01259 (0.00579 - 0.02736), b=3.03 (2.84 - 3.22), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.45 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 (10 of 100).
