The labyrinth includes three semicircular canals and three compartments: saculus, utriculus and lagena; each sac contains one otolith, the lapillus, the sagitta and the asteriscus, respectively (Morales-Nin 2000, Berra & Aday 2004, Popper et al.

The labyrinth is a complex structure which, amongst other components, houses three earstones or otoliths which lie in three confluent compartments, the utriculus, the sacculus and the lagena. Apart from the study of their physiological function, the sagitta, the largest of the otoliths, located in the sacculus, is studied for its variable morphology as well as for its potential as an indicator of the size and age of the fish.
