Coral are extremely ancient animals that evolved into reef-building forms over the last 25 million years. Coral reefs are among the most biologically diverse regions on Earth. Only tropical rainforests might provide homes for more species of plant and animal life. Even though they cover only a tiny fraction (less than .2 percent) of the ocean's bottom, coral reefs contain more than 25 percent of all marine life.
