Other forms of asexual reproduction
Corals may reproduce by fragmentation. This method is most common within fast growing branching corals like Acropora. Sections of branch that break off due to mechanical forces such as wave action or cyclone damage may settle on the bottom and continue to grow, producing new colonies that are genetically identical to the parent.
Some genera may reproduce through fragmentation where the breakup of the colony is controlled internally, by the coral itself. This is termed autotomy. One of the best known examples is that of Diaseris, which may split into a number of sections producing genetically identical, smaller, daughter colonies.
