The stages of differentiation of the inner ear sensory epithelia of the neotenous cave urodele, Proteus anguinus, was studied with light and electron microscopy. Comparative ultrastructural analysis among specimens of different sizes confirms that new sensory cells may be generated throughout life, particularly along the periphery of the saccular macula. The inner ear of Proteus contains at least four types of sensory cells that differ in their apical ciliary part. 
Functional morphology of the inner ear and underwater audiograms of Proteus anguinus (Amphibia, Urodela)
TLDR
Excellent underwater hearing abilities of Proteus are sensory adaptations to cave habitat and the same organ, through air cavities within the body, enables detection of underwater sound pressure changes thus acting as a hearing organ.
Bony labyrinth morphometry reveals hidden diversity in lungless salamanders (Family Plethodontidae): Structural correlates of ecology, development, and vision in the inner ear
TLDR
The morphological correlates of ecology among diverse species reveal underlying evidence of habitat specialization in the inner ear and suggest that there exists physiological variation in the function of the salamander ear even in the apparent absence of selective pressures on the auditory system to support acoustic behavior.

TLDR
The pit organs and canal neuromasts of the gummy shark Mustelus antarcticus were examined using transmission and scanning electron microscopy and both had hair cells with the `staircase' arrangement of sensory hairs characteristic of vertebrate mechanoreceptors.

Postembryonic production and aging of inner ear hair cells in sharks
TLDR
A germinal zone at the leading edge of sensory epithelium growth appears to persist into adult life in sharks, and published reports reinterpreted in light of this evidence suggest that such hair cell population growth may be expected in other anamniotes and that latent growth zones might persist in the ears of amniotes.
A Functional Interpretation of the Electron-Microscopic Structure of the Sensory Hairs in the Cristæ of the Elasmobranch Raja clavata in Terms of Directional Sensitivity
TLDR
Physiologically, the response behaviour of sensory cells in the vertebrate labyrinth has been thoroughly analysed in the semi-circular canals and otolith organs of the labyrinth of the elasmobranch fish, Raja clavata1 and of the frog4.

The ulstrastructure of the saccular and lagenar maculae were studied in 15 species of teleost fishes, using the scanning electron microscope. Particular attention was paid to hair cell orientation
Evidence concerning the morphogenesis of saccular receptors in the bullfrog (Rana catesbeiana)
TLDR
Sometimes in adults and more often in stage‐26 tadpoles one finds the presumably younger peripheral type of hair cell occurring well beyond the limits of the macula proper, and considerable evidence supports the view that one type (“peripheral”) is transformed during macular growth to the other type ( “central”).
Structure and Development of Vestibular Hair Cells in the Larval Bullfrog
TLDR
A far greater number of type A hair cells were found in high frequency sensitive sensory organs (sacculus, amphibian and basilar papillae) than low frequency sensitive vestibular sensory structures (canal cristae, utriculus and lagena), which may suggest that the time period required for the maturation of type B hair cells to their ultimate hair cell types in the low frequency Sensory organs is shorter than in the high frequency sensory structures.
Morphological and fine structural features of the basilar papilla in ambystomatid salamanders (amphibia; caudata)

TLDR
The ambystomatid basilar recess and papilla are compared to auditory end‐organs in other vertebrates, and it is suggested that a basic distinction can be made between aural neuroepithelia in amniotes versus that in nonamniotic vertebrate ears.

TLDR
It now appears that there are at least five different saccular hair cell orientation patterns among teleost fishes, and all of these patterns are found spread through many major teleost taxa.
