Examination of the structures within the cell body revealed comparable features with those found in the inner ear hair cells from bony fish species, although in <jats:italic>P.\u00a0spathula<\/jats:italic> the afferent cell body is almost twice the size. This is the first time that the inner ear hair cells from an Acipenseriform fish have been studied using transmission microscopy, thus providing benchmark anatomical information in relation to the cellular morphology of the afferent receptors from a \u2018healthy\u2019<jats:italic>P.\u00a0spathula<\/jats:italic> ear. Structural information is of assistance in the study of aquatic animal hearing for environmental monitoring purposes, as morphological data can be used to confirm if evidence of raised hearing thresholds from animals exposed to intense anthropogenic noise or other destructive agents (determined using electrophysiological or behavioural techniques) are a direct result of damage to the ultrastructure of the inner ear.<\/jats:p>","DOI":"10.1111\/j.1365-2818.2006.01566.x","type":"journal-article","created":{"date-parts":[[2006,5,22]],"date-time":"2006-05-22T15:47:27Z","timestamp":1148312847000},"page":"36-41","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["The inner ear ultrastructure from the paddlefish (<i>Polyodon spathula<\/i>) using transmission electron microscopy"],"prefix":"10.1111","volume":"222","author":[{"given":"J.
