Short description Morphology | Morphometrics

Dorsal spines (total): 9; Dorsal soft rays (total): 16; Anal spines: 3; Anal soft rays: 10; Vertebrae: 25. Large eyes, diameter of which about one fifth of the head length. Body scales are slightly rough to touch. Body coloration: green above and silvery below with vertical rows of golden spots on the upper sides, tips of the caudal fin are black. Juveniles have dark golden bars on their sides (Ref. 6390). Length of upper lobe of caudal fin < 29.9% SL (Ref. 9701).

Eastern Indian Ocean: endemic to the southern coasts of Australia.

Biology     Glossary (e.g. epibenthic)

Usually found inshore in bays and estuaries over seagrass beds or near areas of seaweed (e.g. kelp), on rocky reefs, and along ocean beaches. Juveniles are found in inshore coastal waters, bays and inlets (Ref. 6390). Feed on small fish and prawns (Ref. 27946).

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Both small, undeveloped ova (eggs) and larger ripe ova are present in the ovary at the same time. This phenomenon suggests that these species are either partial spawners (i.e. only some of the ova are spawned each time) or that the small ova remain in the ovary after spawning and are resorbed (Ref. 27945).
