Inhabits coastal waters and estuaries, but very few data based on reliable identifications (Ref. 189, 11230). Occurs in river (Ref. 12218).

Western Pacific: East China Sea from Hainan north to Port Arthur (Lu-shun) and perhaps to Korea, although the more northerly records could apply to Coila nasus. A single specimen from Phuket Island, Thailand but the provenance seems doubtful. The four specimens from Kerala, India refer to Coila grayii.

Dorsal spines (total): 0; Analspines: 0; Analsoft rays: 80

Maximum size: 200 mm SL

20.0 cm SL (male/unsexed; (Ref. 189))

Body tapering, belly rounded before pelvic fins, with 16 to 19 + 24 to 32 = 41 to 50 keeled scutes from isthmus to anus. Maxilla long, reaching to or almost to base of first pectoral fin ray. Pectoral fin with 6 filaments; rarely 13 or 14 branched fin rays which are longer than those of pelvic fin.

Amphidromous. Refers to fishes that regularly migrate between freshwater and the sea (in both directions), but not for the purpose of breeding, as in anadromous and catadromous species. Sub-division of diadromous. Migrations should be cyclical and predictable and cover more than 100 km.Characteristic elements in amphidromy are: reproduction in fresh water, passage to sea by newly hatched larvae, a period of feeding and growing at sea usually a few months long, return to fresh water of well-grown juveniles, a further period of feeding and growing in fresh water, followed by reproduction there (Ref. 82692).

Inhabits coastal waters and estuaries, but very few data based on reliable identifications (Ref. 189, 11230). Occurs in river (Ref. 12218); also coral reefs (Ref. 58534).
