Brownish with dark blotches along back; faint blotches on mid side, the last on caudal base; fins usually spotted (Ref. 2798).

Spawns in caves.

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).

Dorsal spines (total): 7; Dorsal soft rays (total): 10 - 11; Analspines: 1; Analsoft rays: 10 - 11

Occurs inshore, enters lagoons (Ref. 4343). Found in muddy estuaries and coastal bays (Ref. 4833). Enters lower reaches of freshwater streams (Ref. 2847). Feeds on small fishes, crustaceans and other invertebrates (Ref. 12693).
