After a two-year period we were able to identify 856 corals growing directly on the concrete blocks.Note: Although we have selected to count corals according to depth this is not really an accurate indicator since the amount of available overall surface area for the corals to settle on is not the same at each depth. Please refer to the depth limits only as indications. |
