Spiny dorsal fin situated at mid-point of body. Anal fin inserted slightly forward of second dorsal fin. Dorsal and anal fins mostly scaleless with scales only at the anterior base of fin Pectoral fin high on side and not reaching dorsal fin origin. Tail forked. Body scales with minute spines.

Other Notes

Mugil platanus is a junior synonym of this species.

Siccha-Ramirez et al. (2014) reported that records of Mugil cephalus off South America refer to M. liza. The exact northern extent of M. liza is unknown due to the confusion with M. cephalus. Scale counts are the best way to separate the two species of grey mullets.
