The cave does not have running streams to provide a home for fish or amphibians. Microorganisms. For thousands of years, microscopic bacteria and fungi have thrived in stable, dark cave environments. In Lechuguilla Cave, over 1,000 strains of microbes from the pools, soils, speleothems, corrosion residues and sulfur deposits have been isolated. ................
