The coral is a polyp, an organism that lives in the shallow sea. Its skeleton is composed of limestone and dolomite. The layers of deposition of the skeletons of these polyps form a shallow rock known as Coral Reef.

They thrive in tropical oceans confined between 25 degrees North and 25 degree
south latitudes, Corals are found mainly in the tropical oceans and seas because they require a high mean annual temperature above 20 degree celsius.

Most fishes lay eggs in coral colonies.

Since coral polyps cannot survive above water level, coral reets are found either up to sea level or below it

The coral reefs are more diverse than tropical rainforests because coral reefs have more than 1,000,000 species
