Lobsters use their statoliths (stony structures in their balance organs) for orientation and navigation. However, if their statoliths are replaced with iron filings, they will be responsive to a magnetic field. Therefore, in the presence of a strong magnetic field at the top of the tank, the lobster will turn upside down and grip the underside of the tank lid.
