Ultrastructural changes in the sagitta otolith during ontogenesis of european anchovy from Adriatic Sea

Quali-quantitative ultrastructural changes during ontogenesis of the sagitta otoliths of the inner ear European anchovy from the Adriatic Sea were analyzed by SEM. Crystalline arrangement area presented a complex modification of the crystal growth dimension (TL around 40 mm) and crystalline arrangement complexity. These changes in the ear could be related to ecological changes in mobility and feeding.
