Macrozoobenthos Soft Soils of the Far Eastern Marine Biosphere Reserve

Abstract

This study analyzed the composition and distribution of the macrozoobenthos of the soft soils of the Far Eastern Marine Biosphere Reserve. Found 176 species, classified in six groups: Polychaeta, Bivalvia, Gastropoda, Cumacea, Isopoda, Echinodermata. The greatest variety of typical for polychaete worms (67 species) and bivalves (48 species). Found that the coefficient of variation in the ratio of the number of major taxonomic groups for soft ground of sublittoral reserve (1.02) is slightly higher than for water areas with domination of the soft soils in northern latitudes (area of Spitsbergen and the North Sea), and is closer to that of the bays and coves of the South China Sea and the North-East coast of Australia.
