magnetoception
Magnetoception is the sense that allows an organism to detect magnetic fields. This ability is present in a wide range of organisms, from bacteria and insects to birds, fish, and even some mammals. The exact mechanisms by which magnetoception works are still a subject of scientific research, but several hypotheses exist.
One proposed mechanism involves specialized proteins called cryptochromes, which are light-sensitive molecules found in the eyes
Another theory suggests the involvement of magnetic crystals, such as magnetite, within the organism's tissues. These
Magnetoception is believed to play a crucial role in navigation and orientation for many species. For instance,
