    Doomed dolphins Doomed dolphins Presentation Transcript

    • Shawna Tankersley Period 2
    • Mass death in dolphins Isn’t because of BP’s massive oil spill The cause remains a mystery. No evidence indicating worldwide multi-species crash. Localized areas, stranding and death increased.
    • • Unusual high counts of illnesses & death in bottlenose dolphins towards the gulf.• Bottlenose dolphins in the northern part of the gulf are dying at a higher rate than bottlenose dolphins elsewhere.• No reason found for the issue yet.• We know for a fact humans impact the dolphins life everyday.
    • • When a mass death happens the whole group could be wiped out.• Not only are “ocean-going” dolphins suffering from the mass deaths, the Chinese river dolphin (baiji) was declared extinct in 2006.• This probably happened because of humans.. Fishing gear, underwater explosions or excessive noise that would harm them.
    • Other possible causes Dolphins cant handle abnormal weather. Toxic algae blooms in the water are very harmful. Parasites or pollution can easily kill the food they eat. Disorientation from ships or oil spills can physically hurt the dolphins
