The oxeye tarpon is a bright silver fish with very large eyes, big scales and an upturned mouth, the last ray of its dorsal fin drawn out into a trailing filament. It is a subtropical species found in KwaZulu-Natal estuaries, lagoons and coastal shallows, tolerating brackish and even fresh water.

It has a modified swim bladder that lets it gulp air and survive in poorly oxygenated estuarine water, and it feeds on small fish and crustaceans. A prized light-tackle sport fish that leaps spectacularly when hooked, it is bony and generally released rather than eaten.
