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

ABSTRACT: Ocean acidification, the ongoing decline of surface ocean pH and [CO 3 2 - ] 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 morpho
