ТАКСОНОМИЧЕСКОЕ И ВИДОВОЕ РАЗНООБРАЗИЕ МАКРОЗООБЕНТОСА В ОНЕЖСКОМ ЗАЛИВЕ БЕЛОГО МОРЯ
THE TAXONOMIC AND SPECIES DIVERSITY OF MACROZOOBENTHOS IN THE ONEGA BAY OF THE WHITE SEA

Summary/Abstract: The article describes qualitative (species) composition of macrozoobenthos in the Onega Bay of the White Sea. We have discovered that the composition of macrozoobenthos is characterized by multiple species and taxonomic diversity. It includes more than 140 taxa related to 11 types and 22 classes (subclasses). The single instances of protozoa, sponges, and primrosites were observed in the zoobenthos samples. Tentaculata are represented by four species in two classes, sipunculida and chordates – by one class each, coelenterates – by six species in two classes. The subdominant group was represented by echinoderms, among which ophiuroids (7 taxa) and arthropods (18 taxa) prevailed in terms of species diversity; among the arthropods, the most numerous one proved to be the crustacea class (16 taxa).
