Marine sponges are well-known as a rich source of bioactive substances. This study aimed on screening the hydroethanolic extracts of 22 sponge species colleted at the Pedra da Risca do Meio Marine State Park, Ceará, off the Northeast coast of Brazil, for antiproliferative, antimitotic and hemolytic activity. After collection, the species were immediately immersed in ethanol and stored at low temperatures (-20°C) until use. The hydroethanolic extracts (HEEs) were obtained by evaporation of the immersion solvent and its residue was reconstituted at a concentration of 20 mg/mL in sterile dimethylsulphoxide (DMSO) to be used in the bioassays. Geodia corticostylifera and Monanchora arbuscula were highly active on all performed assays, followed by Amphimedon compressa, which showed a strong inhibitory activity on cultured cell growth and sea-urchin eggs division, but exhibited only a moderate hemolytic activity.
