In Mokiev- sky's opinion the supralittoral lies above the limit of overwash, and the water impregnating it enters the beach owing to its capillarity. The bivalves Donacilla cornea and the polychaete Ophelia bicornia (Oph. taurica ?) are the mass forms of the pseudolittoral of the Crimean coast. In some cases Donacilla gives a biomass of up to 689 g/m2 and 3,100 specimens per m2, and Ophelia yields 394 g/m2 and 400 specimens per m2. Apart from these two dominant forms the following are fairly common: the amphipod Pontogammarus maeoticus, with a maximum biomass of 83 g/m2 and greatest number of specimens of 11,800 per m2; Mytilus mysid, Gastrosaccus sanctus, the isopod Euridice pulchra, and the polychaetes (Spionidae) Nerine cirratus and Nerinides cantabra. Sphaeroma serratum and Idothea baltica are much.
