Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 12; Dorsal soft rays (total): 13 - 14; Anal spines: 2; Anal soft rays: 15 - 16. Six vertical pairs of dark spots on body posterior to a vertical from the base of the first segmented dorsal fin ray; the posteriormost pair of dark spots posteriorly elongated and attenuating onto the base of the caudal fin (Ref. 50537).
Body shape (shape guide): fusiform / normal.
Adults occur in coral reefs (Ref. 50537). Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01047 (0.00461 - 0.02381), b=2.98 (2.79 - 3.17), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 2.0 ±0.00 se; based on food items.
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
