Morphology, morphometry and growth rings of the otoliths: sagitta, asteriscus and lapillus of Selar crumenophthalmus in Manzanillo and Santiago bays in Manzanillo, Colima, Mexico were studied. Differences between sexes, as right and left of the three pairs of otoliths were analyzed. In all cases the growth of the otoliths is eccentric to the core. Relationship between fish length and length and/or width of the otoliths showed that these structures are useful in the growth determination. Four growth rings were identified in sagittae and asterisci.
