Coral types and communities

There are more than 500 species of coral, such as sea fan coral, hard brain coral, bubble coral, mushroom coral, staghorn coral and soft fire coral, grow together. They have a wide range of shapes, sizes and colours, yet they all have the same basic body plan- a simple sacklike stomach and a mouth that is surrounded by a ring of poison filled tentacles. They live side by side with goldfish, giant clams, surgeonfish and many other sea dwellers.
