ResumoJuvenils and adults of Chrysaora láctea, Aurelia aurita and Drymonema gorgo were found in Blanca Bay during summer and efirae of the two first occurred from October to January. These species are commonly found in Brazilian waters. Their occurrence in higher latitudes may be either due to the influence of warm waters coming from north or to the heating of local waters which could main tain their populations temporarily during spring and summer. In this period C. láctea and A. aurita may reproduce as it is suggested by the occurrence of their efirae in the surveyed area.
