Juveniles with dark stripes on belly, becoming spots with growth; adults with or without spots on fin (Ref. 4919).

Biology:  Relatively uncommon in patch reefs and coral slopes near sandy areas of clear lagoon and seaward reefs. Juveniles occur in sandy and weedy inner reefs, adults on clear lagoons and seaward reefs (Ref. 9710). Juveniles inshore, usually on muddy substrates and often estuarine. Adults on deep slopes and range to outer reefs, sometimes swimming high above the substrate or just below the surface. Pelagic larvae may disperse over great distance and juveniles occur in subtropical zone (Ref. 48637). Enter estuaries (Ref. 4833).
