Archaeonommus -> Archaoeboomus
Rather than engulfing cells they touch, some Archeonommus' explosive mitosis comes out in a line which pierce into any poor cell without a protective cell wall injecting genetic messages for forced mitosis in its victims. Larger cells which haven't got the energy to make sudden divisions tend to die quickly from the rapid mitosis leaving a meal for the new species.
