Body elongate; cylindrical anteriorly and becoming more compressed posteriorly. Snout narrowly blunt. Top of head flat. Eye diameter equal to snout length. Subterminal mouth reaches anterior margin of orbit. Teeth with slightly curved tips. Adipose eyelid present (absent in juveniles). Spiny dorsal fin situated anterior to mid-point of body. Anal fin inserted slightly forward of or even with second dorsal fin. Dorsal and anal fins densely covered with small scales. Pectoral fin high on side and not reaching dorsal fin origin. Tail forked. Body scales with minute spines.


Body whitish grading to darker dorsally. Center of scales on mid-body with dark centers forming faint stripes on body. Dorsal, pectoral, and caudal fins with dense melanophores. Second dorsal fin with a dark tip. Ventral fins generally pale with a sprinkling of melanophores. Tail margin dark. A large blotch on the pectoral base and axil. Eye color pale.


Maximum size to 40cm SL


Found inshore and in estuarine waters.


Known from the S. Caribbean Sea and South America from Panama to NE Brazil.

Other Notes

The combination of 9 branched rays in the dorsal and anal fins, dorsal fin being anterior to midpoint of body, and high relative scale counts distinguishes this from all other Mugil species in the region.
