What are ‘Coral polyps’? What are its kinds? State with an example.
Coral polyps are short lived microscopic organisms which live in colonies. They flourish in shallow, mud free and warm waters. They secrete calcium carbonate. The coral secretion ’ and their skeleton form coral deposits in form of reefs.
They are mainly of three kinds :
