fluorescence micrograph of prokaryotes and viruses stained with SYBR Green I. The smallest dots are viruses and larger ones are bacteria or archaea. The bacteria are approximately 0.5 micrometers in diameter.
Epifluorescence photomicrograph of bacteria and viruses like the one above, but with a large pennate diatom in the middle of the field.
Transmission electron micrograph of viruses (dark items) and other similar-sized material concentrated from seawater. The viruses are approximately 50 nanometers in diameter.
