Conteúdo: 	Echinometra lucunter, (Pinda?) is a sea urchin encountered in the Brazilian coast and exposed to high and low temperatures related to low and high tides. Despite their great distribution and importance, few studies have been done on the biological function of their coe-lomocytes. Thus, Echinometra lucunter perivisceral coelomocytes were characterized under optical and transmission electron microscopy. Phagocytic amoebocytes in the perivisceral coelom were labelled by injecting ferritin, and ferritin labelled phagocytic amoebocytes were found in the peristomial connective tissue after injecting India ink into the tissue, indicating the amoebocytes ability to respond to an inflammatory stimulus. Results showed that the phagocytic amoebocytes were the main inflammatory cells found in the innate immune response of E. lucunter . While other works have recorded these phenomena in sea urchins found in moderate and constant temperature, this study reports on these same phenomena in a tropical sea urchin under great variation of temperature, thus providing new data to inflammatory studies in invertebrate pathology
