| Main | Types of Reefs | Primary Producers | Damage to Reefs


A coral reef is a huge mass of calcium carbonate produced entirely from biological activity. It is the most productive marine system and has the greatest amount of diversity per unit square. Coral reefs occupy 0.17% of the earth's surface. Coral Reefs are distributed along the equator in tropical areas. The greatest number of coral reefs occur along the shore line of Indonesia in the Indian Ocean. Distribution of coral can be split up into three basic areas:

coral reef and fish

Western Atlantic-Caribbean

Approximately 60 species
