Embryonic inland silversides, Menidia beryllina, in the early blastula stage were exposed to the water-soluble fraction (WSF) of No. 2 Fuel oil and the oil dispersants Corexit 7664® and 9527®, singly and in combination. An ordinal ranking system was used to score observed daily craniofacial, cardiovascular, and skeletal responses in control embryos and those exposed to 1%, 10%, and 100% concentrations of the WSF of No. 2 Fuel oil, the dispersants Corexit 7664® and 9527® applied at the recommended field application concentrations, and the combination of No. 2 Fuel oil and respective dispersants in seawater. The non-parametric Kruskal-Wallis analysis of variance (ANOVA) and post hoc analyses were used to identify statistically significant differences for control embryos and those exposed to No. 2 Fuel oil and dispersants.
