With today's heightened awareness of the fragility in marine ecosystems, this book serves to enlighten the reader about the actual processes that keep alive one of the planet's most majestic habitat: the coral reefs. Drawing on examples at one of the world's most pristine and highly acclaimed atolls, Layang Layang, the lessons contained in this volume are nevertheless applicable to reefs worldwide, and in particular throughout the Southeast Asian region. The book explores many of the unanswered questions by divers as they explore the marine rain forest equivalents. From symbiotic relationships to rare sightings, from feeding strategies to ecological behaviour, the words and pictures clarify and explain the wonderfully complex coral reef ecosystem in a clear and understandable manner.
