For comparing the morphology and morphometric otolith parameters in Liza aurata of Caspian Sea and Liza klunzingeri of Persian Gulf, 35 otolithes (Sagittae) of every species are extracted from under gills region. After washing, their morphometric parameters measured. These parameters include otolith length, width, thickness, ant rostrum, and rostrum, post rostrum in right and left sagittae. In addition to the otolith outline, mode position and mode opening of the sulcus acusticus were examined. Obtained results shown that otolith shape was different in two species. In both of them otolith was medium in size and long. Their thickness was thin. There was a strong correlation between right and left otolith length and right and left otolith thickness in Liza aurata (p≤0.05).but There was not a correlation between right and left otolith width, between otolith length and width and otolith length and thickness(p≥0.05) There was a strong correlation between right and left otolith length and right and left otolith width in Liza klunzingeri (p≤0.05).but There was not a correlation between right and left otolith thickness, between otolith length and width and otolith length and thickness(p≥0.05). Difference in regression relationship between morphometric characteristics of otolith in two species indicates the latitude and temperature effect on the morphometric characteristics of the two species of mullet fish.
