Linear stability analysis of the system of equations predicts that the growth of solid (coral) structures will be aligned perpendicular to flow, propagating against flow direction. Principal builders of coral reefs are stony corals (Madreporaria), but other important contributors are the hydrocorallines and alcyonarians. As the corals grow and expand, reefs take on one of three major characteristic structures fringing, barrier or atoll. The polyps reproduce either through fragmentation (when a piece breaks off and new polyps form) or sexual reproduction through spawning. Increasing CO2 has the net effect of causing the dissolution of CaCO3. The coasts may be of an island or a continent.
