The timing and location of this spill resulted in crude oil exposure of many commercially and ecologically important fish species, such as mahi-mahi (</span><span style="font-size:11pt;font-family:Arial;color:#222222;background-color:transparent;font-weight:400;font-style:italic;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">Coryphaena hippurus</span><span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">), during their sensitive early life stages (ELS). Mahi produce positively buoyant and rapidly developing embryos. Therefore, ELS mahi may have been directly exposed to the cardiotoxic tricyclic PAHs dominating oil slicks in surface waters for a significant portion of their developmental period. Further, these embryos are transparent and are likely also exposed to simultaneous stressors occurring in surface waters, known to act synergistically in the presence of oil, such as ultraviolet radiation and increased temperatures.</span></p>

Impacts were exacerbated when mahi were exposed to multiple stressors at once, emphasizing the importance of including additional environmentally realistic stressors/variables in future toxicity tests. Buoyancy change as a means of altering vertical distribution provides evidence that marine organisms once presumed immobile, such as embryos, may assert more control over their immediate environment than previously thought.</span></p>
