Ecology of Polydactylus sexfilis
 
Main Ref. Honebrink, R., 1990
Remarks Occurs along sandy and rocky shorelines and over sandy lagoon bottoms, often in zones of turbulence (Ref. 9685). Often encountered in river mouths or brackish mangrove estuaries. Feeds mainly on crustaceans (shrimps and crabs), polychaete worms, other benthic invertebrates; also on teleosts (Ref. 9685). Feeds during the day and at night (diurnal and nocturnal). In Hawaii, small fishes occur in schools along beaches and in sheltered coves from May through August.
