They have an elongated and almost compressed body, with a generally symmetrical and streamlined appearance, one dorsal fin, falcate pectoral fins and a sizable forked caudal fin. Mouth is small and toothless. Body color is olive green, with silvery flanks and dark bordered fins. They have 13-17 dorsal soft rays, 8-10 anal soft rays and 31 caudal fin rays.

Biology
These fishes generally feed on autotrophs, algae and small invertebrates. They tend to school around coasts and islands with coral reefs. The young fry live at sea for two to three weeks and then migrate during the juvenile stage to mangrove swamps, estuaries, and sometimes lakes, and return to sea to mature sexually and reproduce. Females spawn at night up to 5 million eggs in saline shallow waters.
