BEAUTIFUL!!! My son and I love to look at the absolutely amazing and gorgeous pictures of a world most of us will never see because (A) we are not expert scuba divers and (B) it is quickly disappearing. We turn to this book again and again to read about coral polyps, pipefish, lionfish, scorpionfish, sharks, octopus, dolfins, etc. An interview with one of the diver/photographers tells how dangerous it is to get some of the shots. For example, a stingray can bend it's tail up over its head lightning quick to sting anything coming towards it head-on, which could include photographers. My hat is off to these underwater photographers!
I got this at Barnes & Noble on clearance for $14.99. After perusing the book, I say it is probably worth 3-4 times that price.
