Up along the animal kingdom, amphibians also make use of the geomagnetic field. As part of their lifetime tracks, amphibians migrate between feeding sites, breeding sites, and wintering sites. Since they would preferably do this migration on moist and rainy nights, the incorporation of magnetic field in their orientation system is extremely helpful in their navigation. The use of the geomagnetic field has also been seen in turtles. They use magnetic field to aid in homing.
Marine turtles hatch on sandy beaches and then spend their lives out in the open sea.
Every two or three years, mature females return to land to deposit their eggs on the beach where they themselves were born. When we really think about this process, it is quite amazing. Stepping up to the level of more complicated animals of the living world, we still see that mammals also put magnetic field to use, even rodents, whose entire lives are spent within an area of less then 100 meters in diameter. A study on Domestic Horses indicated that these animals probably use a magnetic compass to determine the direction of displacement. Up to this point you are probably wondering how all of these animals are able to perceive the magnetic field.
