Korte beschrijving
Morfologie | Morfometrie
Dorsale stekels (totaal): 15 - 16; Dorsale zachte stralen (totaal): 9; Anale stekels 1; Anale zachte stralen: 20. This species is characterized by the following: minute scales, lateral transverse scales 9-1/1/4-6; lateral line tubules terminale below end of second dorsal; minute orbital cirri, not divided; D1 shorter than D2; head, belly and nape scaleless; with vomerine teeth (Ref. 94009).
Adults are found on coral stones and weeds of intertidal zones (Ref. 94009). 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
Fylogenetische diversiteitsindex (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).
Trofisch niveau (Ref.
69278): 3.0 ±0.3 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref.
120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
