Short description Morphology | Morphometrics

Dorsal spines (total): 12 - 13; Dorsal soft rays (total): 19-23; Anal spines: 3; Anal soft rays: 18 - 20.

Occur in small groups in reef flats, clear lagoon and seaward reefs (Ref. 48636). Benthopelagic (Ref. 58302). Feed on soft and hard corals, also on polychaetes, small crustaceans, and filamentous algae. In Indonesia, usually seen at moderate depths, usually swimming in small groups. Adults are mainly in depth 20-60 m (Ref. 48636). Oviparous (Ref. 205), monogamous (Ref. 52884). Form pairs during breeding (Ref. 205).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02818 (0.01716 - 0.04630), b=3.01 (2.87 - 3.15), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.3 ±0.3 se; Based on diet studies.

Resilience (Ref. 69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Low vulnerability (15 of 100) .

Price category (Ref. 80766): Unknown.
