Abstract : Otoconia appear to have organic substances incorporated into the calcite crystals. Numerous communicating holes are found along the otolithic striola (snowdrift) which would allow free flow of endolymph between the subcupular space and endolymph. The gelatin membrane of otoliths are anchored to the supporting cells by the veil-like gelatin mesh as described by Dohlman. Only long sensory hairs of the hair bundle are partly embedded in the gelatin layer.
