Vivarium Proteus

Southwestern Slovenia


Just near the entrance to the Postojna Cave is the Vivarium, the cradle of a special branch of biology: speleobiology. Postojna provides shelter to dozens of cave-dwelling animal species – visitors can get to know some of the most interesting ones in more detail here, including the 'human fish', as well as the slenderneck beetle, cave squid and cave centipede.
