Confocal images of candidate magnetoreceptor cell. (A) Transmitted light (T). (B) Same cell viewed in confocal reflectance mode (R). Dashed yellow line indicates cell outline. Reflective inclusions inside the cell, with a close-up view (upper right window, scale bar: 2 μm). (C) Confocal fluorescence image showing DAPI labeling of the same cell. N: nucleus. Dashed yellow line: cell outline. (D) Composite image showing the nucleus and the reflective inclusions (red arrow). Scale bar: 10 μm.
