The shortfin mojarra is of the family Gerreidae and reaches 28 cm. It lives in coastal waters and lagoons of the eastern Pacific, from Mexico to northern Peru, over mud or sand bottoms, down to 30 m. It enters brackish water and, in Mexico and Central America, goes up into freshwater rivers. It has thickened upper and lower lips, and its pectoral fin is short, reaching to the anal opening.

identification
Body with thickened upper and lower lips and a short pectoral fin, which reaches the anal opening without reaching the origin of the anal fin. It lives in lagoons and on mud or sand bottoms near the coast. Compare it with the Peruvian mojarra (Diapterus peruvianus), which has a diamond-shaped, very tall body, and with the silver mojarra (Eucinostomus dowii), which has a spindle-shaped, less tall body.
