The early divisions of sea urchin eggs was used as a model to study the effects of static and of 60 Hz sinusoidal magnetic fields. Two species were used ( Sphaerechinus granularis and Paracentrotus lividus ). Eggs were fertilized and exposed in two separate coils to the fields (up to 8 mT). Great care was taken to control the temperature of each sample. No difference was found in the time of the first division that could not be attributed to a temperature difference between samples. Comparison is made with other published data on various species. Bioelectromagnetics 19:494–497, 1998. © 1998 Wiley‐Liss, Inc.
