Although most otoliths of teleost fishes contain aragonite, a detailed survey of the otoliths of serveral species confirms that other crystalline forms of calcium carbonate occur. Otoliths of Hoplostethus atlanticus, Pagrus major, Macruronus novaezelandiae, Merluccius australis, Congiopodus coriaceus, Kathetostoma giganteum, Argentina elongata, Rhomobosolea tapirina, Neophrynichthys latus, Coelorinchus aspercephalus, Paranothothenia microlepidota, and Gonorhynchus gonorhynchus contained the…

TLDR
Comparison of the orientations of lamellae to templates based on the Bragg unit cell structure of twinned aragonite indicated that the lamella widths were in the size range that has been described for sub-daily and daily microincrements in otoliths and provide a potential diffusion sink correction for the radionuclide method of ageing Otoliths.

Fusion of Otoconia: a Stage in the Development of the Otolith in the Evolution of Fishes

TLDR
Three physical chemical processes, Ostwald ripening, Keith-Padden spherulitic growth and carbonate cementation are significant in the chemistry of fusion of otoconia in the evolution of the aragonite teleost otolith.

First record of anomalous otoliths of Menticirrhus americanus in the South Atlantic

TLDR
The Raman spectra show that normal otoliths, that is, without morphological alterations, presented only aragonite in their structure.

Significance of otolith calcium carbonate crystal structure diversity to microchemistry studies

TLDR
Examination of the CaCO3 polymorph composition of otoliths should become more common particularly in studies where results will or may be used to inform management decisions, and future research should work to attribute controls on otolith Ca CO3 polymorph expression using a combination of -omics and material characterization approaches.

Morphology and evolutionary significance of phosphatic otoliths within the inner ears of cartilaginous fishes (Chondrichthyes)

TLDR
IR spectroscopy identified the material to be composed of carbonate/collagen-bearing apatite in all taxa, contradict previous hypotheses suggesting these otoconial structures were composed of calcium carbonate in chondrichthyans.

Mineralogy of the otoliths of naked carp Gymnocypris przewalskii (Kessler) from Lake Qinghai and its Sr/Ca potential implications for migratory pattern

Otoliths are biogenic carbonate minerals whose microstructure and microchemistry have been used for age determination, stock identification, life history and environmental tracing. Using X-ray

Mineralogy and geochemistry of otoliths in freshwater fish from Northern Italy

Asteriscus, sagitta and lapillus otoliths of freshwater fishes (Cyprinids) from the Friuli Plain were mineralogically and chemically analyzed. All the analyzed fish showed that sagitta and lapillus

High incidence of otolith abnormality in juvenile European flounder Platichthys flesus from a tidal freshwater area

TLDR
The sagittal otolith morphology and mineralogy of juvenile European flounder were examined to describe the incidence and types of structural deformities in this species and the morphometry and the mineral polymorph composition of abnormal otoliths did not differ from normal ones.

Otolith crystals (in Carapidae): growth and habit.

Morphometry and composition of aragonite and vaterite otoliths of deformed laboratory reared juvenile herring from two populations

TLDR
Vaterite is less dense than aragonite, yet the concentrations of Ca analysed with wavelengthdispersive spectrometry (WDS) were the same between the two polymorphs, indicating that Ca concentrations measured with WDS are not a good indicator of hypermineralized zones with high mineral density.

Vaterite Otoliths from the Opah, Lampris immaculatus, and Two Species of Sunfish, Mola mola and M. ramsayi

TLDR
It is argued that, based on their otolith mineralogy and morphology, the opah and the sunfish are each side of one of the biochemical and anatomical boundaries involved in the separation of the teleosts from other actinopterygian fish (sturgeons, paddle fish, gars and bowfins).

A CRYSTALLOGRAPHIC STUDY OF VERTEBRATE OTOLITHS

TLDR
The distribution of statoliths and/or statoconia, their texture and their composition within the vertebrate series, show remarkable consistencies; within each class the same kind of static bodies is usually present.

The Morphology and Periodic Structures of the Otolith of the Chinook Salmon (Oncorhynchus tshawytscha), and Temperature-dependent Variation in Otolith Microscopic Growth Increment Width

TLDR
The otolith (sagitta) of the chinook salmon has a variable external crystalline morphology which is related to differences in the growth rate of crystals in different parts of the otolith, resulting in a well-defined series of microscopic growth increments.

Molecular structure and composition of fish otoliths

TLDR
Oxygen and carbon isotope data indicate that the aragonite is formed close to isotopic equilibrium with the sea, which is surprising, because seawater has no direct access to the inner ear where the otolith orginates.

Regional Differences in Otolith Morphology of the Deep Slope Red Snapper Etelis carbunculus

TLDR
Interregional otolith shape affinities for the stocks examined parallel similarities in maximum size and growth rate from the literature, suggesting that growth rate may influence Otolith shape.

The Biological Significance of the Variation in Crystalline Morph and Habit of Otoconia in Elasmobranchs

TLDR
The relationship of exogenous (mostly sand leaked in through the ductus endolymphaticus) to endogenous crystalline calcium carbonate otoconia (Stewart, 1906; Nishio, 1926; Iseltager, 1941) is dwelt on and particles in the inner ear of Torpedo nibilana and T. marmorata are described as grains of quartz and feldspar.
