The mojarras are a family, Gerreidae, of fishes in the order Perciformes.
Mojarras are a common prey and bait fish in many parts of the Caribbean including the South American Coast and Caribbean islands. These species tend to be difficult to identify in the field and often require microscopic examination. Most species exhibit a schooling behavior and tend to exploit the shallow water refugia associated with coastal areas presumably to avoid large-bodied predators.
Mojarra is also commonly used in Latin American countries as a name for various species of the Cichlid family.
