Definitions

The spiral-shaped bony canal in the inner ear containing the hair cells that transduce sound. Its core component is the Organ of Corti, the sensory organ of hearing, which is distributed along the partition separating fluid chambers in the coiled tapered tube of the cochlea. [WP,modified].

homology_notes

Because achieving high sensitivity is generally advantageous for auditory organs, it is not surprising that evidence for cochlear amplification is also seen in nonmammals. Spontaneous otoacoustic emissions (SOAEs) are narrow-band sound signals emitted from the inner ear, and it is generally assumed that their energy derives from the hair-cell molecular motors underlying cochlear amplification. However, all terrestrial vertebrates studied so far (including amphibians) show very similar SOAEs. The most parsimonious explanation for the universality of this phenomena is that some kind of amplifying mechanism is at least as old as land vertebrates themselves.[well established][VHOG]

taxon_notes

The association with 'lagena' in frog and fish comes from HOG, although HOG is inconsistent here, associating lagena with XAO cochlea and ZFA cochlear duct. NBK53175 says: 'In contrast, the ventrally located auditory chambers have undergone more extensive evolutionary modifications. The saccule and lagena are prominent auditory organs in fish but the saccule has a vestibular role in mammals and birds, and the lagena is absent in mammals. The primary au- ditory organ in mammals and birds is the cochlea, which has no known counterpart in amphibians and fish (Riley and Phillips, 2003)'

the cochlea is coiled in most mammals, monotremes being the exceptions.
