Role of Seastars in the Intertidal

What will happen to the intertidal zones if all the seastars disappear? Marine bios know seastars eat mussels and anemones. It is believed that stars keep mussel and anemone populations in check. Without seastars, mussels will probably move down lower on rock faces that look bare, but are actually covered with algae - that the limpets and chitons eat. Where will the limpets and chitons graze if those "bare" rocks are covered by mussels???
