Aside from using broadcast coral spawning techniques to reproduce, corals also reproduce using asexual reproduction. Similar to some plants, the coral polyps produce buds to help produce larger coral colonies. This stony coral, the mountainous star coral (Montastraea faveolata), grows at a rate of up to 5mm per year. The coral in this picture is over 500 years old!
