Yesterday I received 6 new postcards request to Postojna Cave and Town Hall.
That it´s a postcards about Proteus Anguinus!
It´s a salamander, is the only cave-dwelling chordate species found in Europe. In contrast to most amphibians, it is entirely aquatic; it eats, sleeps, and breeds underwater. Living in caves found in Dinaric Alps, it is endemic to the waters that flow underground through extensive limestone of karst of Central and Southeastern Europe, specifically Postojna Cave.
Thanks a lot Postojna Cave.
