Subterranean freshwater bivalves discovered colonizing steel support trusses in abandoned anthracite slope mines exhibit unprecedented chemosynthetic adaptations to Acid Mine Drainage (AMD).

Unlike surface species whose calcium carbonate shells dissolve below pH 6.0, these extremophiles deposit an exterior carapace of heavy iron hydroxides (ferrihydrite & schwertmannite), producing an armored rust sheath that shields against low pH and accelerates localized girder corrosion.
