| The head is analogous to a statolith, the movements of which are monitored by fields of hair sensilla located on the head, neck, and prothorax. |
|
| The combination of the statocysts and the statolith aids the mussel in maintaining equilibrium by sensing gravity. |
|
| The sagittal section contains the statolith and the internal structure of the two lens eyes. |
|
| A ctenophore does not automatically try to keep the statolith resting equally on all the balancers. |
|
| Spatial and temporal variation in statolith and protoconch trace elements as natural tags to track larval dispersal. |
