Heterotrophic flagellates, centrohelid heliozoa and filose amoebae wer e recorded from cultures derived from water collected at marine and fr eshwater sites in the Antarctic. Marine samples were collected in the vicinity of Prydz Bay, southeast Antarctica and freshwater samples fro m Sombre Lake on Signy Island and Crooked and Druzhby Lakes in the Ves tfold Hills.
