Distribution and morphology of choanoflagellates, collared heterotrophic flagellates bearing an extracellular siliceous lorica, were reviewed. Eleven species were reported from the Antarctic Ocean. Three of the eleven species were originally described from the Antarctic and are known to be endemic to the Antarctic. The other eight were found in various oceanic areas. Choanoflagellates had been found in both ice and water, which suggested their wide and abundant distribution in the Antarctic. Ecological significance of the choanoflagellate, Parvicorbicula socialis (MEUNIER) DEFLANDRE, most common species in the Antarctic, was stressed as the food of the Antarctic krill, Euphausia superba DANA. Morphological variation of the lorica structure of P. socialis, caused by water temperature, was discussed on specimens collected in various oceanic areas from polar to equatorial.
