Résumé :	There has been increasing concern over declining global biodiversity due to overexploitation and habitat destruction by humans who now consume 20 to 40% of the global net terrestrial primary productivity. Tropical communities are important in the global economics of biodiversity because it is here that human populations are increasing most rapidly, monetary resources will be most strained and problems of food production, pollution and environmental change will be most acute during the twenty first century. Two of the most diverse natural communities on Earth, coral reefs and rain forests, both occur in the tropics. Coral reefs resemble rain forests in their biologically-generated physical complexity, high species diversity, elaborate specializations of component species. Rain forests and coral reefs are usually considered to represent the two pinnacles of biodiversity on Earth, yet no detailed attempts to quantify the total species diversity on coral reefs have been made. This chapter describes why coral reefs are important for all societies to conserve and manage for the future, addresses the need for training specialists in the systematics of marine organisms, (particularly those who would study the rich and poorly-known tropical regions) and provides the first quantified estimate of the total biodiversity of global coral reefs as compared to rain forests.
