| Abstract: | We exposed the bat starfish, Patiria miniata, to the water-soluble fraction (WSF) of oil from a natural seep near Santa Barbara, California, during the first 48 hours of embryological growth. There were no consistent differences among populations whose parents were from areas with differing levels of hydrocarbon exposure. In a second experiment, the order of decreasing toxicity of crude oils to the embryos was: Monterey Zone > Rincon Zone > Prudhoe Bay > Isla Vista Seep. The results are discussed in relation to the effects of natural seeps and oil characteristics. |
