On Wednesday I got three postcards: one from Slovenia, one from Belarus and one from Singapore.
The card from Slovenia shows a Proteus at the Postojna Cave. The Proteus is an aquatic salamander and the only cave-dwelling chordate species found in Europe. It is endemic to the waters that flow underground through extensive limestone of karst of Central and Southeastern Europe. It is completely adapted to a life of total darkness and the largest troglodytic amphibian in the World.
