An otolith (Greek: ὠτο-, ōto- ear + λῐ́θος, líthos, a stone), also called statoconium or otoconium or statolith, is a calcium carbonate structure in the saccule or utricle of the inner ear, specifically in the vestibular system of vertebrates. The saccule and utricle, in turn, together make the otolith organs. These organs are what allows an organism, including humans, to perceive linear acceleration, both hori… WebOct 14, 2024 · Ontogenetic otolith chemistry patterns revealed by LA-ICP-MS core-to-edge transects in this study are similar to those derived from LA-ICP-MS discrete spot analyses on PBT, as well as probe-based otolith studies of other migratory tuna species including south Pacific albacore Thunnus alalunga , skipjack tuna Katsuwanus pelamus and southern …
