Sea urchin gametes, embryos and larvae can be used for quick, cheap and reliable screening and testing of pharmacologically active substances and pollutants. Effects of fecal pollution of Kotor Bay water and mercury in sediments and water of Risan Bay on embryonic development of spotted sea urchin (S. granularis), were examined. The results showed malformations, blockade of adhesion blastomeras and normal embryonic development. This distortion of development is about the suppression of the normal process of cortical granule exocytosis during activation reaction that starts fertilization, response Ring wave and increased level of free calcium ions in intimately membrane layer.
