Abstract
The data on the composition and distribution of freshwater sponges in Western Siberia was presented. Four species were found in present-day’s lakes and rivers, and one species was found during the palynological and archaeological researches. It was shown that freshwater sponges lived mainly in small rivers and lakes of the forest-steppe and southern taiga zones. One hundred taxons of aquatic invertebrates were registered together with sponges. It was detected that the biomass of sponges in zooperiрhyton was veraciously decreasing northwards.
