Magnetotactic bacteria use magnetic crystals for orientation along geomagnetic field lines
the verdict
SUPPORTED
the evidence backs this
confidence 84/100
Multiple scientific studies confirm that magnetotactic bacteria synthesize intracellular magnetic crystals (magnetosomes) that act as compasses, allowing the organisms to orient and navigate along geomagnetic field lines.
