Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 15; Dorsal soft rays (total): 15 - 17; Anal spines: 3; Anal soft rays: 17 - 19.

Inhabits shallow waters in the Red Sea; deeper in the Andaman Sea, usually at depths of 40 m or more. Caudal fin tips very long (Ref. 48636). A single male is usually seen with several females, commonly on steep slopes. Feeds on planktonic food several meters above the bottom.

Estimates based on models

Preferred temperature (Ref. 123201): 23.8 - 29.3, mean 27.3 °C (based on 348 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

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

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

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).

Price category (Ref. 80766): High.

Nutrients (Ref. 124155): Calcium = 64.7 [38.6, 100.7] mg/100g; Iron = 0.69 [0.44, 1.05] mg/100g; Protein = 18.7 [17.6, 19.6] %; Omega3 = 0.152 [0.100, 0.232] g/100g; Selenium = 27 [15, 48] μg/100g; VitaminA = 207 [76, 565] μg/100g; Zinc = 1.4 [1.0, 1.9] mg/100g (wet weight);
