Short description
Chiavi di identificazione | Morfologia | Morfometria
Spine dorsali (totale) : 16 - 18; Raggi dorsali molli (totale) : 10 - 12; Spine anali: 1; Raggi anali molli: 19 - 21. Males are dark-headed (Ref. 37816).
Adults inhabit surge-swept reef margins (Ref. 1602). Found on rock surfaces under ledges (Ref. 13227) of coral reefs covered with algae (Ref. 90102). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114).

Estimates based on models
Preferred temperature (Ref.
123201): 26.6 - 29.4, mean 28.6 °C (based on 1341 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00562 (0.00258 - 0.01228), b=3.08 (2.89 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.1 ±0.3 se; based on size and trophs of closest relatives
Resilienza (Ref.
120179): Alto, tempo minimo di raddoppiamento della popolazione meno di 15 mesi (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
