"The identity of a magnetic sensor in
animals remains enigmatic. Although the use of the geomagnetic field for
orientation and navigation in animals across a broad taxonomic range has been
well established over the past five decades, the identity of the magnetic-sensing
organ and its structure and/or apparatus within such animals remains elusive—‘a
sense without a receptor’. Recently, we proposed that symbiotic magnetotactic bacteria (MTB)
may serve as the underlying mechanism behind a magnetic sense in animals—‘the symbiotic magnetic-sensing
hypothesis'. https://royalsocietypublishing.org/doi/10.1098/rstb.2019.0595
