More Info


Distribution

Widespread in northern Australia from Shark Bay, Western Australia, to Sydney, New South Wales. Elsewhere the species occurs in the west Pacific - Sulawesi, New Guinea and New Caledonia. 
Inhabits bays, estuaries, mangrove creeks and the lower reaches of freshwater rivers and streams. Juveniles commonly enter freshwater streams, while adults often form schools over sandy areas in estuaries and river mouths. 

Features

Dorsal fin XII, 16; Anal fin IV, 15-16; Pectoral fin 17; Pelvic fin I, 5.
Body quadrangular, strongly compressed. Dorsal head profile steep. Eye moderately large, its diameter somewhat smaller than snout length. Snout rounded. Mouth small, horizontal, not protractile. Teeth villiform, in several rows on jaws; gill membrane not forming a free fold across isthmus.
Scales small, ctenoid covering head, body, caudal fin, and soft parts of anal and dorsal fins; lateral line distinct following back profile.
First dorsal-fin spine procumbent, a deep notch between spinous and soft parts of dorsal fin. Caudal fin from rounded (in juveniles) to truncate; posterior margin of soft portions of dorsal and anal fins oblique.

Size

To around 28 cm SL.

Colour

Greenish or silvery with numerous dark, vertical bars on upper sides and spots, usually smaller than eye, more or less arranged in vertical rows on lower side; lips black; posterior edge of caudal fin and soft portions of anal and dorsal fins with a narrow black margin which disappear in specimens larger than about 6 cm standard length.

Feeding

Omnivorous, feeding on small benthic invertebrates and detritus.

Biology

Little is known of the reproductive biology of this species.

Fisheries

Often taken by recreational anglers in estuaries. 

Remarks

The fin spines are venomous and cause painful wounds.
