The formation of R. venosa metapopulation in the Black Seaand its spreading dynamics on the benthal biocoenoses has been analyzed. The results show that the settling of R. venosa coincided in time with a period favorable for the development of mussel Mytilus galloprovincialis – its main food object in the Black Sea. Further adverse change in the ecosystem has led to a change in diet and as a result the formation of dwarf R. venosa ecoforms and complexly structured local populations. The analysis
