Calcium carbonate otoliths
The utricle and saccule are inner-ear organs that sense gravity and linear movement. It is the presence of small crystals of calcium carbonate called otoliths that allows them to function. This is a coloured scanning electron micrograph of crystals of calcium carbonate found in these inner-ear organs.
