Size / Weight / Age

Max length : 35.0 cm TL male/unsexed; (Ref. 2295); common length : 25.0 cm TL male/unsexed; (Ref. 2295)

Environment

Marine; reef-associated; non-migratory; depth range 15 - 80 m (Ref. 2295)

Climate / Range

Tropical; 35°N - 9°S

Distribution

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.
