Corals are small marine animals. The “hard” type of coral grows with the help of algae, which gives it color and nutrients that help it form a sturdy, stony skeleton. Reefs, which form through the accumulation of hard coral, are a vital ecosystem, supporting an estimated 25 percent of ocean species.
Although they cover less than 0.1% of the earth’s surface, coral reefs are the most biodiverse marine ecosystem in the world. Coral reefs are home to: 4,000 species of reef fish; 840 species of corals; Over 1 million species of other animals
