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.

3. • 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.

4. • 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.

5. 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
