By law, the Republic of San Marino protects its country's wildlife. The Italian Geotriton (Speleomantes italicus), a small amphibian similar to a salamander with strange cave-like habits, is certainly one of the most interesting species in the area. Lacking lungs, it only comes out into the open on cool, wet, rainy nights, hunting for small prey with its long, everted tongue. An exclusively Apennine species that is very localised, with its mimetic colouring of brown, ochre and reddish patches, it is very difficult to observe in the wild. In San Marino, however, this unusual creature emerges from the underground meanderings of Mount Titano like nowhere else known and wanders, shrouded in mists, on the city's stone walls.
Due to its peculiarities, the Geotriton, a friendly protagonist of school books, became the mascot of the 2017 Games of the Small States of Europe and San Marino has already dedicated a postal issue to it in the past.
