Abstract
    A few examples are taken from the literature (mainly the author's own studies) to illustrate the use of sea urchin (Strongylocentrotus pallidus and Echinocyamus pusillus) gametes and embryos as test material in oil pollution studies: Fertilization (rate, effect on nucleus and cytoplasm); Development (effects on skeleton and invagination of the intestine). In general, oil dispersants seem to be much more harmful than crude oil.
