Abstract
The gametes and embryos of Paracentrotus lividus were exposed to vario us dilutions of water-soluble fractions (wsf) of oil prepared at two d ifferent temperatures (18 degrees C and 24 degrees C) to observe devel opmental defects during fertilization and larval stages up to pluteus. Emulsions at 24 degrees C have yielded better fertilization rates and development of larvae against emulsions at 18 degrees C. In general, developmental defects were increased with increasing wsf of oil and it s toxicity decreased with increasing temperature.
