Etymology: Gymnocranius: Greek, gymnos = naked + Greek, kranion = skull (Ref. 45335). More on authors: Temminck & Schlegel.
Environment: milieu / climate zone / depth range / distribution range
Ökologie
; seewasser riff-verbunden; standorttreu; tiefenbereich 15 - 80 m (Ref. 2295). Tropical; 35°N - 9°S
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.

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.
