The last post I wrote was a piece on Troglobites (which can be found here: http://on.fb.me/1AnfDqN). A Troglobite is an animal that lives in a cave, which is adapted to it’s surroundings to the extent they cannot live on the surface. Today I shall discuss the other type of underground fauna, stygofauna.
Stygofauna reside in fresh groundwater systems, such as caves in the subterranean environment. There are three types of stygofauna; Stygophiles, Stygoxenes, and Stygobites. Stygophiles inhabit both the surface and subsurface aquatic environments. Stygoxenes are occasionally found in subterranean water but are generally found above the surface. Finally, Stygobites are always found in underground waters.
