Description
The spotfin mojarra is a small, mirror-silver fish of the family Gerreidae (mojarras) reaching about 21 cm. The laterally compressed body stands out for its far downward-protrusible, tube-shaped mouth, with which the fish sucks prey from the soft bottom. The species forms schools over sand and mud bottoms of coastal water, estuaries and lagoons along the western Atlantic coast from the USA to Brazil and tolerates brackish water. On the bottom it searches for worms, small crustaceans and molluscs. Through its great numbers it is an important prey fish for larger fish and seabirds and is also used as bait.
