In comparison to a substiantial body of information on monogonont Rotifera, there has been relatively little work on the bdelloid biogeography in Poland. Of the 450 species known in the World only 85 were recorded in Poland and 31 - in the Tatra Mountains until 2007. Elaboration of samples taken from different habitats: water, moss, lichens and litter, and tree lichens in the Tatra National Park in July 2008 revealed 23 taxons of Bdelloidea, 14 of which had not previously been found in the rotifer fauna of Poland.
