Short description Morphology | Morphometrics

Dorsal spines (total): 12 - 13; Dorsal soft rays (total): 23-25; Anal spines: 3; Anal soft rays: 17 - 19.

Occur primarily along outer reef slopes, in current channels. Juveniles in aggregations around isolated patch reefs, adults in large schools well above the bottom (Ref. 9710). In Indonesia, adults most common in depth 40-50 m, reported to 200 m (Ref. 48636). Benthopelagic (Ref. 58302). Feed on plankton. Juveniles may act as cleaners (Ref. 9710); also observed in adults (Ref. 48636). Oviparous (Ref. 205). Form pairs during breeding (Ref. 205).

Estimates based on models

Preferred temperature (Ref. 115969): 19.1 - 28.1, mean 26.1 °C (based on 501 cells).

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5039 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02188 (0.01082 - 0.04423), b=3.01 (2.84 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.4 ±0.45 se; based on food items.

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Low vulnerability (16 of 100) .

Nutrients (Ref. 124155): Calcium = 47.9 [24.9, 95.4] mg/100g ; Iron = 1.3 [0.7, 2.3] mg/100g ; Protein = 19.6 [18.4, 20.7] % ; Omega3 = 0.217 [0.120, 0.404] g/100g ; Selenium = 14.3 [6.6, 30.1] μg/100g ; VitaminA = 44.8 [11.3, 170.9] μg/100g ; Zinc = 0.88 [0.54, 1.46] mg/100g (wet weight);
