Potholing features of this cave are large halls, chamber, sedimentations of stalactites and stalagmites, many lakes, few waterfalls, number of streams, and also often fog in the parts of “Absolon channel”. It has rich cave′ s world with almost 200 different animal species, of which 91 troglobionate and 37 of them were found and described on this place, which makes this cave one of its kind according to bio-differences.
