I found, after seeing MacGillivray Freeman's IMAX film Dolphins, that I wanted to know more. The book follows the basis of the film, but goes into much more detail. This book is a superb account of what it is like to study and be around dolphins in the WILD. Cahill's style of writing makes you feel as if you are with him each night as he recounts a day of activity and research. He doesn't "write down" to the reader, i.e., you feel as if you're right there with him, learning along the way. He conveys a true sense of real-life scientific adventure that is fun and intriguing. The incredible pictures alone, many from the IMAX film, are worth buying the book for. I'm a conservative and will not tolerate "tree-hugger" political agendas. This book, like the film, is far from being one that attempts to drill dolphin conservation into your head. Instead, it offers a refreshing angle that provides the reader the knowledge to draw his/her own conclusions about these fascinating animals. Even the lovely scientist, Dr. Kathleen Dudzinski, who Cahill makes the main subject of the book, lets the dolphins "sell themselves" vs. her preaching conservation. It is quite enlightening and is certainly one to keep on the coffee table.
