Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 100 - 105; Anal spines: 0; Anal soft rays: 71 - 84. SL to 18 cm.

Inhabit shallow reefs (Ref. 1602). Benthic (Ref. 58302). Uncommon species (Ref. 34024). Oviparous, with oval pelagic eggs floating in a gelatinous mass (Ref. 205). Mature at 46 cm SL (Ref. 34024). Size of 18 cm SL given by Ref. 37816 seems in error.

Estimates based on models

Preferred temperature (Ref. 123201): 24.5 - 29, mean 25.4 °C (based on 56 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00380 (0.00153 - 0.00942), b=3.13 (2.91 - 3.35), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.6 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (50 of 100).
