Pacific Coral Reefs

Coral reefs are unique ecosystems of plants, animals, and their associated geological framework. Although they cover less than 0.5% of Earth's surface, coral reefs are home to an estimated 25% of all marine species. Of the total coral reef habitat in United States waters, about 75%, or more than 16,000 square kilometers (6,000 square miles), is located in the Pacific Ocean.
