Abstract

Proteus anguinus is endemic stygobiont found in Slovenia, sorounding area of Trieste in Italy, Croatia and Bosnia and Herzegovina. It lives in subterranean waters of the Dinaric karst. The analysis of literature data and personal communication with biospeleologists show that in Croatia here is 68 localities where olm presence was recorded at least once. Acording to recent data, there are 37 confirmed localities, 10 certain, but unavailable, 14 potential and 7 which are most likely to be incorect. In this part I listed data on first records for each of those localities and give comments. In the second part of this paper, there is an analysis of Proteus anguinus bibliography. It shows that first papers were more related to distribution, while the later studies include anatomy, behavior and biology of the species. The latest researches are dealing with genetics. Also, I want to emphasize the need for active protection of this globally, threatened species. The olm is threatened because of it's limited distribution and small population size. Negative effects of survival of this species are degradation of groundwater systems, infrastructure development, industrial pollution and illegal collection of specimens.
