Kentrophoros sp. (2 of 2) (IMAGE) Max Planck Institute for Marine Microbiology Caption The same species of Kentrophoros stained with a fluorescent dye that stains its DNA green. The three bright spots in the middle are the three cell nuclei of the eukaryotic host. The green 'haze' elsewhere are the tightly-packed bacterial symbiont cells, too small to be individually distinguished in this image.
