Asymmetry analysis was conducted on four morphometric bilateral characters and one meristic character of Leiognathus equulus (Forsskål) collected from the Sea of Oman at the city of Muscat.

Increasing asymmetry values with fish length were noted in preorbital and postorbital distances and head length. This might be the result of incomplete development.
