They typically form compact colonies of many identical individual polyps. Coral species include the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton. Coral reefs are the most diverse of all marine ecosystems. They teem with life, with perhaps one-quarter of all ocean species depending on reefs for food and shelter. This is a remarkable statistic when you consider that reefs cover just a tiny fraction (less than one percent) of the earth’s surface and less than two percent of the ocean bottom. 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. Corals form true reefs when they grow close together and deposit layer after layer of limestone, several feet high. Many different kinds of fish depend on coral reefs for food and shelter—places to hide from voracious predators like sharks, groupers and snappers.

Coral reef, ridge or hummock formed in shallow ocean areas by algae and the calcareous skeletons of coral polyps and other coelenterates. A coral reef may grow into a permanent coral island. Often called ‘rainforests of the sea,’ coral reefs are home to a spectacular variety of organisms. The largest coral reef in the world is Australia’s Great Barrier Reef, which is over 1,000 miles long and covers around 133,000 square miles. Why are coral reefs important? Healthy coral reefs play a crucial role in providing coastal protection, habitats for marine life, and even key ingredients for potential new medicines. Coral reef diversity Because of the diversity of life found in the habitats created by corals, reefs are often called the "rainforests of the sea." About 25% of the ocean's fish depend on healthy coral reefs. Fishes and other organisms shelter, find food, reproduce, and rear their young in the many nooks and crannies formed by corals.
