While doing my researchon dolphins  I found an evolutionary tree . This evolutionary tree shows the evolutionary relationship.

Evolutionary tree is  from: http://www.dolphin-way.com/dolphins-%E2%80%93-the-facts/evolution/

Did youknow?  To prevent drowning while sleeping only half of a dolphin brain goes to sleep the other half stay awake so it can breathe.

I hypothesis that dolphins have strong teeth they are carnivores, mostly eating fish and squid. if dolphins didn’t have strong teeth they would not be able to chew squid because squids have hard tentacles with sharp nails looking object.

 Bottlenose dolphins not only have individual “names,” technically signature whistles they use to identify themselves, but they also copy the whistles of companions and family members likely as a means of calling out to those specific animals just like humans call each other by their  name.  Both humans and dolphins are  mammals, so both have mammary glands, and hair on their skin, and they have 7 cervical vertebrae as humans do.Both are mammals, so both have mammary glands, and hair on their skin, and they have 7 cervical vertebrae as humans do. Dolphins have bigger brain than humans. This piece of information is form Take Part and Answers.

 I predict that dolphins  might not live for  a long time due to  the slaughter of more than 20,000 dolphins and porpoises off the coast of Japan every year, and how their meat, containing toxic levels of mercury, is sold as food in Japan and other parts of Asia, often labeled as whale meat, the hunt still goes on find out what you can do to help these poor dolphins.  The majority of the world is not aware this is happening. From The Cove a documentary.
