Diagnoses of all species of these groups within Ukraine are specified. Malacofauna of the Sea of Azov revised as well as the fresh-water waters of Northwest Azov Sea Shore. The zoogeographic structure of the Miocene Sarmatian Basin updated - 161 species of gastropod mollusks, from which 55 % are endemic for the new Sarmatian biogerm provinces are discovered. Actual borders of viviparid area in reservoirs of Eurasia are outlined, the biogeographical changes which have occurred for last 40 years are marked. The basic features of morphological variability радулы Viviparus and Contectiana in ontogenetic aspect are established. It is established, that in the left inflows of Dnepr sponges of the family Spongillidae show certain selectivity to quality and resistance of a substratum on which the colony develops. The analysis of features of their spatial distribution on polytypic reservoirs testifies that the least tolerant in conditions of inflows of Dnepr is Spongilla lacustris while the greatest conservatism in a choice of a substratum show Ephydatia muelleri and Eunapius fragilis. The catalogue of Mysidacea of the investigated region, detailed on places of distribution and ecological preferences of these animals is made. It is determined, that mysids in conditions of Black Sea Coast is inherent severe being to the certain type of bottom. Modern changes of development Mysidacea and Cumacea testifies to deterioration of a natural condition of the investigated reservoirs of the Black-Azov Sea Coast.
