The fauna of Spartina alterniflora from upper and lower shore levels has been monthly studied, from August 1981 to July 1982, in the Cananeia estuarine region, southern coast of São Paulo State, Brazil (25º02'S - 47º56'W). Biological samples were obtained by quadrats from two transects parallel to the water level. The mean density for the upper transect was 3,230 ind/m² and 2,403 ind/m² for the lower transect. Isopoda was the dominant group at both belts, Polychaeta was present consistently at lower transect and Gastropoda was at upper one. Monthly fluctuations of densities of several groups was related to plant biomass.
