world's smallest living organism

Biologists Jill Banfield and Brett Baker discovered what could be the world’s smallest living thing, the enigmatic Archaea microbes found in a slime pool in a deep underground mine:

Once Baker had found gene segments (ribosomal RNA) from three Archaea, he was able to fish the microbes out of the slime soup and found that they were extremely small, around 200 nanometers in diameter, the size of large viruses. Bacteria average about five times this diameter.
