Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 9; Anal spines: 2; Anal soft rays: 9 - 10. This species is characterized by the following: D VI-I; 9, A II, 9; an intermittent black stripe from the snout to the middle of the opercle; no black blotch on the caudal-fin base (Ref. 109581); semi-transparent body with yellowish sheen on head and belly; side of snout with black spot or short stripe; each caudal fin lobe with blackish submarginal band; greatest depth of body 3.8-4.3 in SL (Ref. 90102).

Biology     Glossary (e.g. epibenthic)

Forms large shoals among rocks or above corals of lagoon patch reefs (Ref. 1602). Often schools with R. gracilis (Ref. 37816). Spreads out at night, floating mid-water to catch plankton (Ref. 48635).

Estimates based on models

Preferred temperature (Ref. 123201): 26.9 - 29.3, mean 28.7 °C (based on 2354 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01096 (0.00509 - 0.02362), b=3.09 (2.91 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.5   ±0.50 se; based on food items.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
Nutrients (Ref. 124155):  Calcium = 240 [130, 589] mg/100g; Iron = 1.52 [0.75, 2.68] mg/100g; Protein = 19 [18, 20] %; Omega3 = 0.162 [0.075, 0.360] g/100g; Selenium = 33.4 [12.9, 78.3] μg/100g; VitaminA = 73.4 [20.3, 263.7] μg/100g; Zinc = 2.98 [1.77, 4.66] mg/100g (wet weight);
