Short description Morphology | Morphometrics

Dorsal spines (total): 10; Dorsal soft rays (total): 10; Anal spines: 3; Anal soft rays: 8 - 10.

Inhabits subtidal reef flats, lagoons, and seaward reefs (Ref. 9710). May be solitary or in groups (Ref. 90102). Sometimes forms aggregations of about a hundred or more individuals. Feeds at night on benthic invertebrates like crabs and gastropods, occasionally on small fish. Usually marketed fresh.

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01549 (0.00909 - 0.02638), b=3.02 (2.88 - 3.16), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).

Trophic Level (Ref. 69278): 3.7 ±0.57 se; Based on food items.

Resilience (Ref. 69278): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Low to moderate vulnerability (29 of 100) .

Price category (Ref. 80766): Very high.
