Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 75.0 cm TL male/unsexed; (Ref. 34024)

Short description Morphology | Morphometrics

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

Biology     Glossary (e.g. epibenthic)

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 of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00380 (0.00152 - 0.00950), 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. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (49 of 100) .
