These organisms can be found living in subterranean water-filled karst cavities and in water bodies in above-ground caves. This life comprises many ancient species of crustaceans, such as Microcharon, Microcerberus, Stygctsellus and the archiannelid, Troglochaetus. To strengthen the data and information management system for biodiversity conservation, Romania participated in the UNDP/GEF project entitled Support to Alignment of the National Biodiversity Strategy and Action Plan (NBSAP) with the CBD and Development of a Clearing House Mechanism.
