If you love dolphins, you will love this book. It is very informative, and describes all aspects of dolphins. It describes sounds dolphins make, and what those sounds mean. Where do dolphins live, how they breath, and how they help each other. As a grown-up I learned something new about dolphins. The book also provides some background about the author and why the author wrote the book. It used real pictures for illustration which I think is a good idea to help children learn about animals.
