A combination of federal, state and private funds has been spent on the investigation so far, with almost all of it earmarked for the increases in staff needed to perform necropsies or process the dead samples (including about $200,000 in federal emergency grant funds). Previous studies determined that the majority deaths associated with other mammals occur on farms and that horses and cattle account for 90% of farm accidents. While we're not sure whether or not this sexually arouses the dolphin, we do know that dolphins get sexually aroused. Dolphins, other marine mammals weakened by pollution, scientists say.

Because of the potential danger, officials at the Commerce Department's National Marine Fisheries Service have even released fliers with warnings that "dozens of bites have been reported" and "people have been pulled underwater" by the animals. Perhaps porpoises and dolphins competed for food, the scientists reasoned, or perhaps the porpoises were seen as a threat to young or ill dolphins. Preventing potentially fatal farm animal encounters should be a better promoted and supported public health initiative, Forrester explained.
