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 Territories | 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.

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

Phylogenetic diversity index
(Ref. 82804) 		PD50 = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.01698 (0.00730 - 0.03949), b=2.98 (2.78 - 3.18), 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).
Fishing Vulnerability
(Ref. 59153) 		Moderate vulnerability (38 of 100). 🛈
Price category
(Ref. 80766) 		High.
