Scanning electron Microscopy of a small biofilm piece captured during seismic in situ experiment. In Kopanang Mine 138 pieces of biofilm were captured in the period 20–40 minutes after the borehole was reopened. Six pieces contained nematodes. All exhibited the same curled up appearance as in this picture indicating the specimens were in their survival stage (dauer stage) in suspended animation. Four of the six pieces were transferred to a petri dish and reawakened and were subsequently identified as Poikilolaimus oxycercus. Scale bar: 20 µm.
