From: Eye-like ocelloids are built from different endosymbiotically acquired components

Extended Data Figure 4

a, Still frame from a video of Warnowia sp. b, Erythropsidinium sp. c, Nematodinium sp. with a nematocyst (arrowhead). d, The ventral side of Nematodinium sp. showing red pigmentation of the retinal body. e, Epifluorescence image of the same cell and angle, showing red fluorescence of the retinal body excited by 505 nm light. f, Nematodinium sp. showing a bright spot of reflectivity (that is, ‘eyeshine’) (arrowhead) in the ocelloid. Scale bars, 10 μm.
