MammalLike all dolphins, Bottle Nose Dolphins are mammals.
I don't really know what you're trying to say. Are you asking What is important about the existence of bottle nosed dolphins? Because if so, I do have an answer. They help clean the oceans from garbage, they are a form of entertainment, plus, they help scientists out by sending them updates through underwater mail. You know there is an underwater lab where scientists research things right? Well, who do u think delivers mail and stuff? The dolphins. I also read that they give company to those who are handicapped. Like children with disabilities and adults, too. They save lives as well. There are many stories of how dolphins save human lives. How? By pushing drowning people to shore. I read all of this in a children's non-fictional book by the way. =) (Dolphins are by far the best mammals in the planet...they are my favorite)
