 It is home to olms ("Proteus anguinus"), an amphibian who can live about 90 to 110 years.This animal is endemic in the Triestine Karst and along the Croatian coast, and was bought from Postojna Caves in Slovenia by Alberto Parolini in 1830.Parolini aimed to test whether the animal was able to adapt to the slightly different living conditions, but never discovered the results as the olms were forgotten, until they were rediscovered by cave divers in 1967.
