Indo-West Pacific: southern Japan to the Indo-Malaysian region, probably eastward to India. Has often been confused w/ the young of Gymnocranius grandoculis, hence its distributional limits are somewhat obscure. Records of Gymnocranius griseus from the Western Indian Ocean probably pertain to Gymnocranius grandoculis.

Espinhos dorsais (total) : 10; Raios dorsais (total) : 9 - 10; Espinhos anais: 3; Raios anais : 9 - 10.

In sheltered coastal bays and sand and mud slopes in depths over 20 m (Ref. 48635); also in coastal trawling grounds. Juveniles sometimes in shallow estuaries on algae reefs (Ref. 48635). Sometimes forms schools. Feeds on bottom-living invertebrates. Sexually mature upon reaching 15-17 cm SL. Sometimes caught with handlines and marketed dried (Ref. 9775) or fresh. In Hong Kong live fish markets (Ref. 27253).

Estimates based on models

Preferred temperature (Ref. 123201): 24.2 - 28.8, mean 28.1 °C (based on 445 cells).

Índice de diversidade filogenética (Ref. 82804): PD₅₀ = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01778 (0.00761 - 0.04154), b=2.97 (2.78 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nível Trófico (Ref. 69278): 3.2 ±0.44 se; based on food items.

Generation time: 5.0 ( na - na) years. Estimated as median ln(3)/K based on 1 growth studies.

Resiliência (Ref. 120179): médio(a), tempo mínimo de duplicação da população 1,4 - 4,4 anos (K=0.22).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (38 of 100).

Categoria de preço (Ref. 80766): High.

Nutrients (Ref. 124155): Calcium = 39.5 [20.2, 69.1] mg/100g; Iron = 0.519 [0.283, 0.847] mg/100g; Protein = 19.2 [17.2, 21.2] %; Omega3 = 0.128 [0.075, 0.187] g/100g; Selenium = 34.9 [21.0, 60.2] μg/100g; VitaminA = 81.5 [24.8, 238.5] μg/100g; Zinc = 1.32 [0.94, 1.79] mg/100g (wet weight);
