Preventing potentially fatal farm animal encounters should be a better promoted and supported public health initiative, Forrester explained. So technically killer whales are not whales at all, but in fact dolphins, meaning there is an even higher number of human fatalities caused by the dolphin community. But something didnt add up, because red tide was reportedly absent at the time and that toxin would not explain some of the lesions found on the dolphins.
