Description

The strongspine silverbiddy is a fish of the mojarra family (Gerreidae) from the Indo-West Pacific. The species has an elongate, silvery body with a highly protrusible mouth that it can extend downward as a tube to sift the bottom. Adults live in clear coastal waters to about 50 m deep; juveniles often stay in freshwater-influenced estuaries and lagoons. On the bottom it sifts small invertebrates from the sediment. The species is harmless to humans.
