Eucinostomus argenteus is a member of the family Gerreidae. The Eucinostomus genus is distinguished from other members of the family Gerreidae by the interhaemal cone, an unusual cone-shaped structure formed from the first two anal pterygiophores that encloses the posterior end of the air bladder (Matheson and McEachran 1984).The spotfin mojarra is a small to medium sized fish with a compressed body and protrusible mouth. The body depth is 32.3 to 38.5% of the standard length. It is a silvery fish that is heavily pigmented with a uniform pattern of 7 dorsal bars separated by 6 dark lateral spots. The snout has distinct V-shape pigmentation and the dorsal fin is clear with fine speckling (Matheson and McEachran 1984).
