It is shown that the distribution of species composition of malacofauna of the coastal zone is uneven. The species diversity of malacofauna of the coastal zone of the Novorossiysk Bay includes 17 species of mollusks: 11 species (65% of all species found) belong to the class Gastropoda , 5 species (29%) to the class Bivalvia , and 1 species (6%) to the class Polyplacophora . The basis of abundance throughout the studied coastal part is created by bivalve mollusks, predominantly of the genus Mytilaster , and gastropods of the genus Rissoa . The Black Sea is inhabited by representatives of 3 classes of mollusks: gastropods, bivalve mollusks and shell mollusks. Species composition of coastal mollusks by status consists of 3 groups: mass (5 species), common (4 species) and rare (8 species).
