The monogonont composition of two polar regions : Spitsbergen (Arctic) and King George Island (Antarctica) is compared. Four different freshwater habitats (moss banks, moraine ponds, nearshore ponds and thaw ponds) were surveyed. Twenty monogonont species on Spitsbergen and 11 species on King George Island were found. Euchlanis dilatata and Notholca salina were the most numerous monogononts in both regions respectively. The maximum number of species on Spitsbergen was observed in nearshore ponds (19), while on King George in thaw ponds (8). In each habitat species diversity was higher on Spitsbergen than on King George Island. Species composition was different because of : different sources of colonisation, longer colonisation on Spitsbergen than on King George Island, better developed tundra habitat on Spitsbergen with more abundant flora, and smaller geographical isolation of Spitsbergen from the place of colonizers origin.
