Etymology: Gymnocranius: Greek, gymnos = naked + Greek, kranion = skull (Ref. 45335 ) .  More on authors: Temminck & Schlegel .

Environment: milieu / climate zone / depth range / distribution range Ecology

Marine; reef-associated; non-migratory; depth range 15 - 80 m (Ref. 2295 ).   Tropical; 35°N - 9°S

Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

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 .

Size / Weight / Age

Maturity: L m   ?   range ? - ? cm
Max length : 35.0 cm TL male/unsexed; (Ref. 2295 ); common length : 25.0 cm TL male/unsexed; (Ref. 2295 )

Short description Morphology | Morphometrics

Dorsal spines (total): 10; Dorsal soft rays (total): 9-10; Anal spines : 3; Anal soft rays : 9 - 10.

Biology     Glossary (e.g. epibenthic)

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. 115969 ): 24.2 - 28.8, mean 28.1 °C (based on 445 cells). Phylogenetic diversity index (Ref. 82805 ):  PD 50 = 0.5010   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.01778 (0.00754 - 0.04192), b=2.97 (2.78 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245 ). Trophic level (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. Resilience (Ref. 120179 ):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.22). Vulnerability (Ref. 59153 ):  Moderate vulnerability (38 of 100) . Price category (Ref. 80766 ):   High . Nutrients (Ref. 124155 ):  Calcium = 44.3 [25.8, 77.5] mg/100g ; Iron = 0.539 [0.335, 0.850] mg/100g ; Protein = 19.6 [17.6, 21.4] % ; Omega3 = 0.126 [0.075, 0.187] g/100g ; Selenium = 35.7 [21.1, 57.5] μg/100g ; VitaminA = 71.3 [20.8, 201.0] μg/100g ; Zinc = 1.27 [0.85, 1.79] mg/100g (wet weight);
