Environment: milieu / climate zone / depth range / distribution range
Ecology
Marine; reef-associated; non-migratory; depth range 100 - 200 m (Ref. 86942). Deep-water; 35°N - 34°S
Indo-West Pacific: tropical, known only from a few scattered localities.
Length at first maturity / Size / Weight / Age
Maturity: Lm 31.0 range ? - ? cm
Max length : 55.0 cm TL male/unsexed; (Ref. 2295); common length : 35.0 cm TL male/unsexed; (Ref. 2295)
Dorsal spines (total): 10; Dorsal soft rays (total): 10; Anal spines: 3; Anal soft rays: 10. The inner surface of the pectoral fin axil without scales. Overall color is silvery-gray with yellowish suffusion; scale margins are narrowly brownish. Indistinct dark blotches or bars are sometimes apparent on the body. The lips are whitish to yellow. The fins are yellow, faint brown spotting may be present on soft dorsal, anal, and caudal fins. A narrow blackish bar runs across the base of the pectoral fin.
Inhabits the outer edge of the continental shelf. Feeds on bottom-living invertebrates and small fishes. Caught mainly with bottom longlines and bottom trawls (Ref. 9775).

Estimates based on models
Preferred temperature (Ref.
123201): 14.4 - 24.3, mean 19.9 °C (based on 186 cells).
Phylogenetic diversity index (Ref.
82804): PD
50 = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01862 (0.00668 - 0.05187), b=2.96 (2.72 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.7 ±0.52 se; based on food items.
Generation time: 3.3 ( na - na) years. Estimated as median ln(3)/K based on 2
growth studies.
Resilience (Ref.
120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low to moderate vulnerability (28 of 100).
Nutrients (Ref.
124155): Calcium = 7.76 [3.70, 20.47] mg/100g; Iron = 0.227 [0.089, 0.528] mg/100g; Protein = 18.9 [16.9, 21.2] %; Omega3 = 0.157 [0.067, 0.348] g/100g; Selenium = 11.4 [3.9, 31.1] μg/100g; VitaminA = 14.7 [2.0, 110.9] μg/100g; Zinc = 0.323 [0.185, 0.529] mg/100g (wet weight);
