From the introduction: “In this book we have tried to share with you some of our underwater adventures and, through the photographs, to bring to you something of the beauty and fascination of the underwater life here in the warm waters surrounding Southern Arabia. It’s not a comprehensive field guide to the marine life of the region, nor is it intended to be a specific study of any particular group of animals. Rather we hope to introduce the reader to some of more fascinating life forms that exist above and below the tide line, where to find them and why they occur where they do.
