Freshwater and brackish “oasis” fauna in the deep Black Sea

摘要

Present paper reports on the possible existence of recent freshwater fauna in the Black Sea. Based on information available from malacology, ecology, paleontology, stratigraphy, hydrogeology and observations in situ, the presence of freshwater biota on the shelf and continental slope is discussed, including the existence of aerobic life forms in the Black sea deep-water cavity.
