Wonderful Corals and Coral reefs

Coral reefs represent some of the oldest and most complex communities of plants and animals on Earth. The primary structure of a coral reef is a calcareous skeleton formed by marine invertebrate organisms known as cnidarians, which are relatives of sea anemones.
There are essentially three types of coral reefs – fringing reefs, barrier reefs, and atolls. Fringing reefs form borders along the shoreline. Barrier reefs also parallel the shoreline but are found further offshore and are separated from the coast by a lagoon. The atoll is typically a ring-shaped reef.
About 33% of all of the fishes of the world live and depend on coral reefs. Within the reef, there are hiding places for fish and other marine organisms.
The largest coral reef in the world is the Great Barrier Reef near Australia. It is more than 1,250 miles long.
