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.
Body shape (shape guide): elongated.
Body shape (shape guide): elongated.
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
|
Phylogenetic diversity index (Ref. 82804) |
PD50 = 0.5078 [Uniqueness, from 0.5 = low to 2.0 = high]. |
| Bayesian length-weight | a=0.00363 (0.00158 - 0.00837), b=3.15 (2.95 - 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 (46 of 100). 🛈 |
