| Description: An internal row of iron-rich magnetite crystals, each enclosed by a membrane, functions like a compass needle, allowing this bacterium to detect Earth's magnetic field. This feature allows M. magnetotacticum to locate its preferred habitat, low-oxygen sediment, since it is hypothesized that the magnetosome guides the bacterium downward, where the direction of Earth's magnetic fields point downward. Cells use their flagellum to move from less favourable to more attractive locations.
