Habitat, feeding, spawning, and nursery grounds for over 1 million aquatic species are provided by healthy coral reefs. Coral reefs are also home to many of the world’s rarest and most endangered species.
These include the critically endangered coral reef shark (Carcharhinus novaeangliae), which is listed as “vulnerable” by the U.S. Fish and Wildlife Service (FWS) and the World Conservation Union (WCO), and is threatened by overfishing, pollution, climate change and over-harvesting for the pet trade.
Coral reefs also play an important role in maintaining the health of marine ecosystems by providing food and shelter for fish and other marine life, as well as providing habitat for marine mammals and seabirds.

Smith, a professor of ecology and evolutionary biology at the University of California, Santa Cruz.
