In fishes, as in other vertebrates, the vestibular end-organs are divided into a gravity receptor system, with three subdivisions and an angular acceleration receptor system. The gravity receptor system on each side consists of utricular, saccular, and lagenar maculae, each covered by an otolith (reference 1); (...)considerations have led to our rethinking issues related to the origin of several aspects of vertebrate hearing, and to the view that many basic auditory functions evolved very early in vertebrate history, and that the functions observed in more `advanced' vertebrates, such as birds and mammals, are frequently modifications of themes first encountered in fishes, and perhaps even more ancestral animals (reference 2).[well established][VHOG]
