It boasts remarkable biodiversity and is home to 60 aquatic and 40 land species. Among them is the endemic cave-dwelling aquatic salamander known as the olm or “human fish” (Proteus anguinus). Planina Cave has the largest population of these bizarrely beautiful creatures roaming its depths. Spectacular!
