Iron-Eater

Excavation has uncovered fresher samples of the bizarre, membranous tissue covering the planet-spanning machinery on …! Through careful analysis, our researchers have concluded this organic substance appears to be the byproduct of a vicious, iron-eating bacteriophage, or ferrophage! This alien virus infects a unique species of bacteria, co-opting the bacterium's biological processes in order to dissolve the surface of ferrous metal alloys. After this intense chemical disintegration, the virus then absorbs the iron atoms needed to sustain its continued replication! In a bizarre example of xenological parasitism, the ferrophage spreads further and deeper along the old machinery, leaving a trail of biofilm, comprised of dead bacteria and slough matter, in its wake.
