--- In this investigation toxins of the venom of the sea anemone Anthothoe chilensis (Lesson, 1830) have been studied, from the tentacles and bodies of alive animals collected between 8 and 10 meters of depth in the Island Cabinza-San Lorenzo. Three precipitated fractions with ammonium sulfate and three precipitated fractions with acetone were used to make assays in vitro and one assay in vivo. It was observed that the proteins contained in the venom of A. chilensis have a molecular weight between 14 and 94 kDa. The presence of carbohydrates was evidenced in all the evaluated fractions and by stain PAS of gels SDS-PAGE the glycoproteins presence were detected. All the fractions showed to have hemolytic, phospholipase and proteolytic activities. The acetonic fraction I had the higher hemolytic activity, the acetonic fraction III had the greater phospholipasic activity. When the fractions were assayed on the sea urchin eggs embryonic development, they showed to have morphologic effects like lisated blastules, early exogastrulation, and abnormal prisms and pluteus larvae. Cytological effects like gastrulaes with less mitotic configurations, heteropycnotic nuclei, karyorrhexis and giant nuclei were observed. The evaluated fractions showed to produce hypersensitivity type I in mice, without getting to trigger anaphylactic shock.
