“…Unlike otoliths, for which there are many experimental studies examining how extrinsic (environmental) and intrinsic (biological) factors affect otolith chemistry (e.g. Kalish 1989;Fowler et al 1995;Bath et al 2000;Elsdon and Gillanders 2003;Reis-Santos et al 2013;Sturrock et al 2015;Martino et al 2017;Izzo et al 2018), few studies have examined these effects on shark vertebrae. In fact, we are aware of only a single study that directly examines the effect of extrinsic and intrinsic factors on elasmobranch vertebral chemistry .…”

Reconstructing movements and environmental histories of sharks may be possible by using the element composition of vertebrae, but unlocking such possibilities requires an understanding of the effects of extrinsic and intrinsic factors on element composition. We assessed water temperature and pH effects (independently and in combination) on vertebral chemistry of Port Jackson sharks while accounting for intrinsic factors (condition and sex) using indoor aquaria and outdoor mesocosm environments, where the latter may better reflect natural field conditions. We analysed eight element:Ca ratios (7Li, 8B, 24Mg, 55Mn, 65Cu, 88Sr, 138Ba and 238U) by laser ablation inductively coupled plasma mass spectrometry and found positive temperature-dependant responses for multiple elements, including B:Ca, Mn:Ca, Sr:Ca and Ba:Ca (r2=0.43, 0.22, 0.60 and 0.35 respectively), whereas pH had a minor effect on vertebral Mg:Ca and Li:Ca (r2=0.10 and 0.31 respectively). As shown for teleost otoliths, condition affected element composition (Mn:Ca), suggesting potential physiological influences on element uptake. The suitability of vertebral chemistry as a natural tag appears to be element specific, and likely governed by a suite of potentially codependent extrinsic and intrinsic factors. Overall, variations in vertebrae chemistry show promise to reconstruct movements and habitat use of cartilaginous fishes. Yet, further research is required to understand the ubiquitous nature of the findings presented here.

“…Precipitation of calcium carbonate may occur in the form of vaterite and calcite, this change in carbonate crystallization has been attributed to chemical changes in endolymph and/or environmental stress (David & Grimes, ; Gauldie, ; Tomás, Geffen, Allen, & Berges, ). Experimental studies have pointed out that changes in physicochemical parameters such as pH and temperature of the marine environment can cause alterations in the acidity of endolymph, a liquid in which otoliths are immersed (Martino, Doubleday, Woodcock, & Gillanders, ;Munday, Hernaman, Dixson, & Thorrold, ). Due to the alkaline property of endolymph, saturation and deposition of aragonite occurs in otoliths (Payan, Pontual, Boeuf, & Mayer‐Gostan, ).…”

Sagitta otoliths are usually formed of calcium carbonate polymorphs as aragonite. The objective of this study was to verify which carbonate polymorph is predominant in the sagitta otolith of Menticirrhus americanus and check whether this pattern remains in otoliths with morphological alterations. Otoliths of M. americanus were obtained from five sites on the southeast‐south coast of Brazil (São Sebastião (SS) 23°45′S–45°24′O, n = 29; Cananéia‐Iguape Estuarine Complex (CI) 25°02′S–47°54′O, n = 30; Paranaguá Estuarine Complex (PEC) 25°28′S–48°20′O, n = 35; Itapoá (IT) 26°07′S–48°36′O, n = 31; Laguna (LA) 28°28′S–48°46′O, n = 13). The characterization of carbonate polymorphs of otoliths was performed through Raman spectroscopy, a photonic and non‐destructive technique that analyzes molecular vibrations induced by laser. We analyzed 138 pairs of M. americanus otoliths, of which eight otoliths from different pairs presented morphological alterations (SS n = 1, CEP n = 5, IT n = 1, LA n = 1). The Raman spectra show that normal otoliths, that is, without morphological alterations, presented only aragonite in their structure. Among the otoliths that presented morphological alterations, the Raman spectra allowed to identify in six otoliths the deposition of aragonite and in only two otoliths the deposition of vaterite (one specimen of the PEC and one of SS).

“…While most available studies quantified simple morphometrics to analyze pCO 2 effects on otolith morphology, the most informative among them augmented morphometrics with other analyses, including complex shape analyses (e.g., Fourier analysis) (Munday et al, 2011a; Munday et al, 2011b; Simpson et al, 2011; Martino et al, 2017; Mirasole et al, 2017); mass, volume and density analyses (Bignami, Sponaugle & Cowen, 2013; Bignami et al, 2013); and compositional analyses (e.g., LA-ICPMS) (Munday et al, 2011b; Hurst et al, 2012; Martino et al, 2017; Mirasole et al, 2017; Coll-Lladó et al, 2018). Similarly, scanning electron microscopy can be used to screen for treatment effects on aspects of otolith morphology and composition that, although typically overlooked in simple morphometric analysis, may impact ear function.…”

Ocean acidification alters morphology of all otolith types in Clark’s anemonefish (Amphiprion clarkii)

Ocean acidification, the ongoing decline of surface ocean pH and [CO] due to absorption of surplus atmospheric CO2, has far-reaching consequences for marine biota, especially calcifiers. Among these are teleost fishes, which internally calcify otoliths, critical elements of the inner ear and vestibular system. There is evidence in the literature that ocean acidification increases otolith size and alters shape, perhaps impacting otic mechanics and thus sensory perception. Here, larval Clark’s anemonefish, Amphiprion clarkii (Bennett, 1830), were reared in various seawater pCO2/pH treatments analogous to future ocean scenarios. At the onset of metamorphosis, all otoliths were removed from each individual fish and analyzed for treatment effects on morphometrics including area, perimeter, and circularity; scanning electron microscopy was used to screen for evidence of treatment effects on lateral development, surface roughness, and vaterite replacement. The results corroborate those of other experiments with other taxa that observed otolith growth with elevated pCO2, and provide evidence that lateral development and surface roughness increased as well. Both sagittae exhibited increasing area, perimeter, lateral development, and roughness; left lapilli exhibited increasing area and perimeter while right lapilli exhibited increasing lateral development and roughness; and left asterisci exhibited increasing perimeter, roughness, and ellipticity with increasing pCO2. Right lapilli and left asterisci were only impacted by the most extreme pCO2 treatment, suggesting they are resilient to any conditions short of aragonite undersaturation, while all other impacted otoliths responded to lower concentrations. Finally, fish settlement competency at 10 dph was dramatically reduced, and fish standard length marginally reduced with increasing pCO2. Increasing abnormality and asymmetry of otoliths may impact inner ear function by altering otolith-maculae interactions.
