Resumo: | The larval development of Cyrtograpsus angulatus Dana, 1851 was studied in laboratory through eggs hatched from ovigerous females collected in mole of Rio Grande, Rio Grande, State of Rio Grande do Sul, Brazil. Three experiments (A, B, C) were carried out involving 250 larvae, derived from three ovigerous females. The experiments A and B, were carried in a climatically box with temperature among 22 and 25ºC, and salinity among 32 and 34‰. The experiment C in a room without controlled temperature, in a constant salinity of 30‰. The larvae were maintained individually and food consisted of rotifers Brachionus plicatillis Müller, 1786 and microscope algae Tetraselmis sp. The development of C. angulatus Dana, 1851 comprises five stages of zoea and one megalope. The main morphological characters that allow the identification of the first stages of C. angulatus, are analyzed with respect to the other Brazilian species of the family Grapsidae.
