A coral reef is a structure in shallow ocean areas that is formed mainly by stonelike coral skeletons. Corals are small marine animals that live in all oceans of the world. Some individual corals, called polyps, are colonial, which means they grow together in large groups called colonies. As they die, they leave behind their skeletons.

Coral reefs provide a natural habitatand massive protection for different species of fish. They are not plants; they are living organisms that provide an environment for fishes to breed. Without them, fishes in the ocean are homeless. According to professor Christie’s lecture, corals are colonial organisms that need to be exposed to sun, in order f...
Coral reefs are fragile ecosystems. Because corals need warm, sunlit water to live, they often grow close to the top of the water. Being so close to land makes them often be damaged by poisons and dirt that can come from boats and the land nearby. Dirt makes the water more cloudy, which makes the sunlight less. Poisons can bleach and kill corals. A...
The building block of coral reefs are the skeletons of generations of hard corals, composed of calcium carbonate. As each polyp dies, it leaves behind its skeletal structure, upon which the next generation of polyps grow, enlarging the reef. Grazing fish (such as parrotfish), sea urchins, spongesand other organisms break down the coral skeletons in...
Most present-day coral reefs were formed after the last ice age when melting ice caused the sea level to rise and flood the continental shelves. This means they are less than 10,000 years old. As coral reef communities were established on the shelves, they built reefs that grew upwards, keeping pace with the rise in sea level. Reefs that did not ke...

Many types live together in groups called colonies. Several different types of corals together can form enormous colonies. These colonies are called coral reefs. The largest coral reef in the world is the Great Barrier Reef off the coast of Australia.
definition: a structure that rises up from the bottom of the sea and is made up of the hard skeletons of tiny sea animals called corals. Coral reefs are found in warm, shallow sea waters around the world.
