More Info


Distribution

Broome, (and possibly south to Exmouth Gulf) Western Australia, around the tropical north to the Hawkesbury River, New South Wales. Elsewhere the species occurs in the tropical, Indo-west Pacific: Persian Gulf east to southern China, Taiwan, New Guinea and Australia.
Inhabits shallow coastal waters, estuaries, rivers and shallow coastal waters. The River Jewfish can tolerate turbid waters.

Features

Dorsal fin X-XII, 27-32; Anal fin II, 7-8; Gill rakers (lower limb 9-15). 
Snout rounded but not swollen or projecting; mouth large, oblique; upper jaw extending backward below posterior half of eye; no barbel on chin; teeth in narrow bands, well differentiated into large and small in both jaws, but none canine-like; gill rakers slender, about half length of gill filaments at angle of arch. Second anal-fin spine moderately long, 24-42 % of head length. 
Scales on head cycloid (smooth). 
Swim bladder hammer-shaped, the first pair of arborescent appendages entering head beyond transverse septum and sending a palmate branch to the front of pectoral arch. 
Sagittal otolith (large earstone) with a tadpole-shaped impression, the head of which has its long axis lying obliquely to that of sagitta and the tail expanded and deepened as a hallow cone connected with the head by narrow groove.

Feeding

Juveniles feed mostly on crustaceans, and feed on fishes as they grow.
