The habitat of Proteus anguinus ("human fish") is very limited. It lives in the subterranean fresh waters of the Dinaric Alps. It prefers underground water systems in Karst formations, with calm, well oxygenated water and a constant low water temperature. Proteus anguinus was first discovered and described in Slovenian Karst, and most researches were made on animals found in the Slovenian territory as well.Apart from its unique cave morphology, the image and the recognition of the Postojna cave is, in the big part, build on "human fish". Even more, Postojna Cave is the cradle of speleobiology, the branch of biological science, which studies the living world underground. It was in Postojna Cave that the first specimens of most groups of cave fauna were found. In terms of variety and number of species of cave fauna, the Postojna-Planina cave system is the richest cave system in the world. Postojna cave is very near Ljubljana and you are very welcome to visit. Here is some pictures (you can move the cursor on the cave pictures for detailed information, the last one is interesting):
