Description

The slender mojarra is a silvery coastal fish of the family Gerreidae from the western Atlantic. The species reaches about 20 cm and has a slender, silvery body and a highly protrusible, downward-pointing mouth with which it searches sand for prey. Unlike many related mojarras it does not enter estuaries or fresh water and stays in slightly deeper water and on banks farther offshore. The diet consists of small bottom invertebrates that it sifts from the sediment. The species regularly occurs in schools over sandy bottoms.
