Postojna Cave is the pearl of Slovenia with very beautiful stalactites and stalagmites. I had the opportunity to visit this cave, but what is an attraction besides the appearance is what sets it apart from other caves is the human fish. The human fish (lat. Proteus anguinus) is a reptile amphibian from the family Proteidae. A really rare specimen that lives up to 80 depths where there is no light.
