Query: Wonderful beautiful book!

I had already seen the IMAX movie on Dolphins and was amazed and more awed by them then before and I didn't think that was possible! Dolphins are my favorite animal and for good reason. Next to humans they are the smartest creature on earth and unfortunately us humans are killing them! The movie doesn't really go in to that neither does the book.........but had to say it. Anyways the book is large and beautifully illustrated! Covers several topics and isn't boring at all! The pictures alone make the book worth it!
