Coral reefs are made up of coral, the shell-like structures that the tiny sea animals build as their "houses". Each year, a living coral reef builds a new layer of coral; you might think of it as the collected skeletons of all the previous inhabitants of the reef. (Except that for coral, their "bones" are on the outside.)
