Bat
Microbats make use of magnetoreception, in that they have a high sensitivity to the Earth's magnetic field, as birds do. Microbats use a polarity-based compass, meaning that they differentiate north from south, unlike birds, which use the strength of the magnetic field to differentiate latitudes, which may be used in long-distance travel. The mechanism is unknown but may involve magnetite particles.
Magnetoreception
Some of the earliest studies of amphibian magnetoreception were conducted with cave salamanders ("Eurycea lucifuga)". Researchers housed groups of cave salamanders in corridors aligned with either magnetic North-South, or magnetic East-West. In ensuing tests, the magnetic field was experimentally rotated by 90°, and salamanders were placed in cross-shaped structures (one corridor along the new North-South axis, one along the new East-West axis). Considering these salamanders showed a significant preference for test corridors which matched the magnetic alignment of their housing corridors, researchers concluded that cave salamanders have the capacity to detect the Earth’s magnetic field, and have a preference for movement along learned magnetic axes.
