Quick Summary

The spotfin mojarra (Eucinostomus argenteus) is a species of fish belonging to the family Gerreidae. These fish are found in marine environments across most warm regions of the world, with some species occasionally entering brackish or freshwater habitats. Mojarras are characterized by their silvery, compressed bodies and a distinctive, highly protrusible mouth that forms a tube when opened. While they can reach up to 35 cm (14 inches) in length, most species, including the spotfin mojarra, typically do not exceed 25 cm (10 inches). The spotfin mojarra is widely distributed along the Atlantic, Gulf of Mexico, and Pacific coasts of North America, and it can be found in freshwater areas of river systems.1
