The author does a wonderful job of examining the lifestyles and mating habits of a broad range of turtles. Chelonians (turtles and tortoises) are thoroughly examined here. In fact, there is so much information packed into these pages that it can become slightly confusing as the author jumps from one species to another while discussing a single topic. As a resident of Florida and an avid scuba diver, I was extremely disappointed to discover that there were no photos of the four most common marine turtles found here. I had hoped for, and sorely needed, photos of each along with some kind of guide on how to distinguish between them. In this regard, this book falls woefully short. There are, however, plenty of photos of hard-to-find, freshwater turtles from remote places on the globe that practically no one will ever see. At least the book didn't cost much!
