	Stygofuna play an important role in prokaryotic transport in freshwater reserves. they enhance the transport of prokaryotes through aquifers. prokaryotes associated with stygofauna may up to 5 orders of magnitude higher in abudnace and transported up to 34x faster than bulk groundflow. As a community, prokaryotes play a role in the biosphere and purifying groundwater. Stygofauna's movement and excretion in groundwater systmes are thougth to meditate transfer of organic matter through the aquifer.

	[[File:caves.jpg\|thumb\|left\|Diagram of cave showing formation of stalagmites and stalactites]] Caves are the most common environments for subterranean ecology. A cave, also called cavers, is a natural opening in the earth, formed through various types of natural processes. Most caves are formed by a chemical reaction between groundwater and bedrock composed of limestone dolomite. Rain water picks up carbon dioxide from the wait as it penetrates the soil, turning into a weak acid.[2]		[[File:caves.jpg\|thumb\|left\|Diagram of cave showing formation of stalagmites and stalactites]] Caves are the most common environments for subterranean ecology.
